Pre-Stage Magnetic Coil to Enhance Helicon Mode Excitation on a Small Helicon Plasma Experiment (HPX)  

NASA Astrophysics Data System (ADS)

Small helicon plasmas have been employed in various capacities from industry to spacecraft propulsion. At the Coast Guard Academy Plasma Lab (CGAPL), a small Helicon Plasma Experiment (HPX) is being developed to utilize the reputed high density (10^13 cm-3 and higher) at low pressure (.01 T) [1] Helicon Mode Plasmas. HPX will become a high temperature and density diagnostic development test-bed for future laboratory investigations in addition to becoming a tool for future spacecraft propulsion devices. HPX Plasmas are created by imparting directed energy into a Pyrex tube preloaded with Ar gas with fill pressures on the order of 10^4 mTorr utalizing a power supply and matching box can deliver up 250 W of power in a 20 MHz to 100 MHz frequency range. It has been demonstrated [1] that a uniform magnetic field in lower energy level plasmas can facilitate a decrease in inertial effects, which promotes energy conservation within the plasma and provids the necessary external energy in the plasma's magnetic field to reach the Helicon Mode. HPX employes an electromagnet to establish this uniform field. An acceleration coil, currently under construction, will be used to increase the plasma velocity to facilitate partcle and optical probing within the vacuum chamber for experimental analysis. Initial accuracy and calibration measurements of the relative magnetic fields created by both electromagnets will be reported.[0pt][1] K. Toki, et al., Thin Solid Films 506-507 (2005).

PlasmaLab/Eco-Plasma - The future of complex plasma research in space  

NASA Astrophysics Data System (ADS)

The next Russian-German cooperation for the investigation of complex plasmas under microgravity conditions on the International Space Station (ISS) is the PlasmaLab/Eco-Plasma project. Here, a new plasma chamber -- the ``Zyflex'' chamber -- is being developed. The chamber is a cylindrical plasma chamber with parallel electrodes and a flexible system geometry. It is designed to extend the accessible plasma parameter range, i.e. neutral gas pressure, plasma density and electron temperature, and also to allow an independent control of the plasma parameters, therefore increasing the experimental quality and expected knowledge gain significantly. With this system it will be possible to reach low neutral gas pressures (which means weak damping of the particle motion) and to generate large, homogeneous 3D particle systems for studies of fundamental phenomena such as phase transitions, dynamics of liquids or phase separation. The Zyflex chamber has already been operated in several parabolic flight campaigns with different configurations during the last years, yielding a promising outlook for its future development. Here, we will present the current status of the project, the technological advancements the Zyflex chamber will offer compared to its predecessors, and the latest scientific results from experiments on ground and in microgravity conditions during parabolic flights. This work and some of the authors are funded by DLR/BMWi (FKZ 50 WP 0700).

Honeycomblike large area LaB6 plasma source for Multi-Purpose Plasma facility  

NASA Astrophysics Data System (ADS)

A Multi-Purpose Plasma (MP2) facility has been renovated from Hanbit mirror device [Kwon et al., Nucl. Fusion 43, 686 (2003)] by adopting the same philosophy of diversified plasma simulator (DiPS) [Chung et al., Contrib. Plasma Phys. 46, 354 (2006)] by installing two plasma sources: LaB6 (dc) and helicon (rf) plasma sources; and making three distinct simulators: divertor plasma simulator, space propulsion simulator, and astrophysics simulator. During the first renovation stage, a honeycomblike large area LaB6 (HLA-LaB6) cathode was developed for the divertor plasma simulator to improve the resistance against the thermal shock fragility for large and high density plasma generation. A HLA-LaB6 cathode is composed of the one inner cathode with 4in. diameter and the six outer cathodes with 2in. diameter along with separate graphite heaters. The first plasma is generated with Ar gas and its properties are measured by the electric probes with various discharge currents and magnetic field configurations. Plasma density at the middle of central cell reaches up to 2.6×1012 cm-3, while the electron temperature remains around 3-3.5eV at the low discharge current of less than 45A, and the magnetic field intensity of 870G. Unique features of electric property of heaters, plasma density profiles, is explained comparing with those of single LaB6 cathode with 4in. diameter in DiPS.

Automation of a remote plasma-enhanced chemical vapor deposition system using LabVIEW  

NASA Astrophysics Data System (ADS)

The remote plasma-enhanced chemical vapor deposition (RPCVD) system is an experimental low temperature Si/Si-Ge epitaxy system. This paper describes an integrated hardware/software automation package developed for the RPCVD system. Aspects of the system controlled by the package include pneumatic gas valves, mass flow controllers (MFCs), and a temperature controller. The package was developed on an Apple Quadra 950 platform using LabVIEWTM 3.1 and associated data acquisition and control hardware supplied by National Instruments and other vendors. The software interface allows the user to operate the system through a virtual control panel which displays critical system parameters such as chamber pressure, chamber temperature and gas flow rates, along with the states of the gas valves and the MFCs. The system can also be run in the recipe mode, in which a sequence of steps are read in from an ExcelTM file. A simulation routine scans each recipe for possible errors such as violation of valve interlocks while the recipe is being loaded. All actions, whether in the manual mode or the recipe mode, are recorded in a log file. Finally, since many of the gases used in the RPCVD process are toxic and/or flammable, there is an emphasis on safety in the entire control scheme. A safety monitor routine constantly checks for valve interlocks and pressure-valve interlocks. Upon detecting an illegal state, it automatically takes necessary action to bring the system into a safe state. In addition to these software safety features, there are also hardware interlocks to deal with such situations as power outages.

The BErkeley Lab Laser Accelerator (BELLA): A 10 GeV Laser Plasma Accelerator  

NASA Astrophysics Data System (ADS)

An overview is presented of the design of a 10 GeV laser plasma accelerator (LPA) that will be driven by a PW-class laser system and of the BELLA Project, which has as its primary goal to build and install the required Ti:sapphire laser system for the acceleration experiments. The basic design of the 10 GeV stage aims at operation in the quasi-linear regime, where the laser excited wakes are largely sinusoidal and offer the possibility of accelerating both electrons and positrons. Simulations show that a 10 GeV electron beam can be generated in a meter scale plasma channel guided LPA operating at a density of about 1017 cm-3 and powered by laser pulses containing 30-40 J of energy in a 50-200 fs duration pulse, focused to a spotsize of 50-100 micron. The lay-out of the facility and laser system will be presented as well as the progress on building the facility.

Bead injection extraction chromatography using high-capacity lab-on-valve as a front end to inductively coupled plasma mass spectrometry for urine radiobioassay.  

PubMed

A novel bead injection (BI) extraction chromatographic microflow system exploiting a high-capacity lab-on-valve (LOV) platform coupled with inductively coupled plasma mass spectrometric detection is developed for rapid and automated determination of plutonium in human urine. A column attached to the LOV processing unit is loaded online with a metered amount of disposable extraction chromatographic resin (up to 330 mg of TEVA (abbreviation for tetravalent actinides)) through programmable beads transport. Selective capture and purification of plutonium onto the resin beads is then performed by pressure driven flow after preliminary sample pretreatment. The analytical results demonstrate the large capacity of bead surfaces for uptake of Pu within the tailor-made LOV platform that fosters processing of large-sized biological samples, e.g., 1 L of human urine, along with good reproducibility for automatic column renewal (0.319 ± 0.004 g, n = 5). The chemical yields of plutonium were averagely better than 90% under the optimal experimental conditions, and the entire analytical procedure could be accomplished within a short time frame (<3 h) as compared to manual counterparts (1-2 days). Therefore, the developed system is well suited for expedient analysis of low-level plutonium in urine of exposed individuals as required in emergency situations. PMID:23339705

Comparison of two lab-made spray chambers based on MSIS™ for simultaneous metal determination using vapor generation-inductively coupled plasma optical emission spectroscopy.  

PubMed

The objective of this study is to evaluate the performance of two lab-made systems based on the Multimode Introduction System (MSIS™) and the modified MSIS™, to generate and introduce vapors of Ag, Cu, Cd, Cu, Ni, Sn, Zn, and also Au in the ICP torch. An univariate procedure was used to select the optimized working conditions (Ar flow, sample, reductant and waste flows, and reagent concentrations). Optimum conditions for working with modified MSIS were: nitric acid concentration 0.35 M, 8-hydroxyquinoline concentration: 40 mg L(-1), sodium borohydride concentration: 1.75% (w/v)+0.4% (w/v) NaOH, argon purge flow to sweep the vapors to the torch: 1.2 L min(-1), sample flow and sodium borohydride flows: 2.3 L min(-1); waste flow: 7.7 mL min(-1). For the optimum working conditions for lab-made MSIS in dual mode the concentration of 8-hydroxyquinoline was 225 mg L(-1), the Ar purge flow was 0.75 L min(-1), and the conventional nebulization flow was 2.3 L min(-1). The sensitivity obtained was higher using the lab-made MSIS than using the lab-made modified MSIS or a forced outlet gas-liquid separator. The limits of detection were better for Au, Cd, Sn than those obtained using conventional nebulization; the measurements were precise (RSDs?5% in dual mode) and a good accuracy was obtained in the determination of Cd, Cu, Ni and Zn in a wastewater reference material using aqueous calibration and the lab-made MSIS in dual mode.

Paleotempestology Lab  

NSDL National Science Digital Library

This introductory lab introduces students to stratigraphic correlation and the dating of geologic materials. Students analyze sediment cores derived from coastal marshes that preserve a record of past hurricane activity. The task is for students to assess the past frequency and intensity of hurricane activity in the region from which the cores were derived. In teams, students log the sedimentological variations in the cores. Then each individual student builds stratigraphic columns for each core. Based on their stratigraphic columns, students try to preliminarily correlate hurricane events between the cores. In small teams, they then collectively decide to "purchase" absolute dates using a fixed budget to test their preliminary correlations and arrive at an overall interpretation of the hurricane activity in the region.

plasmas  

NASA Astrophysics Data System (ADS)

As-deposited HfO2 films were modified by CHF3, C4F8, and mixed C4F8/O2 plasmas in a dual-frequency capacitively coupled plasma chamber driven by radio frequency generators of 60 MHz as the high frequency (HF) source and 2 MHz as the low frequency source (60/2 MHz). The influences of various surface plasma treatments under CHF3, C4F8, and C4F8/O2 were investigated in order to understand the chemical and structural changes in thin-film systems, as well as their influence on the electrical properties. Fluorine atoms were incorporated into the HfO2 films by either CHF3 or C4F8 plasma treatment; meanwhile, the C/F films were formed on the surface of the HfO2 films. The formation of C/F layers decreased the k value of the gate stacks because of its low dielectric constant. However, the addition of O2 gas in the discharge gases suppressed the formation of C/F layers. After thermal annealing, tetragonal HfO2 phase was investigated in both samples treated with CHF3 and C4F8 plasmas. However, the samples treated with O-rich plasmas showed monoclinic phase, which indicated that the addition of O plasmas could influence the Hf/O ratio of the HfO2 films. The mechanism of the t-HfO2 formation was attributed to oxygen insufficiency generated by the incorporation of F atoms. The capacitors treated with C4F8/O2 plasmas displayed the highest k value, which ascribed that the C/F layers were suppressed and the tetragonal phase of HfO2 was formed. Good electrical properties, especially on the hysteresis voltage and frequency dispersion, were obtained because the bulk traps were passivated by the incorporation of F atoms. However, the H-related traps were generated during the CHF3 plasma treatments, which caused the performance degradation. All the treated samples showed lower leakage current density than the as-deposited HfO2 films at negative bias due to the reduced trap-assisted tunneling by the incorporation of F to block the electrons transferring from metal electrode to the trap level.

Plasma Levels of Uric Acid, Urea and Creatinine in Diabetics Who Visit the Clinical Analysis Laboratory (CAn-Lab) at Kwame Nkrumah University of Science and Technology, Kumasi, Ghana  

PubMed Central

Introduction: Diabetes mellitus is one of the most common metabolic diseases worldwide. This metabolic disorder contributes greatly to the significant proportion of the burden of renal damage and dysfunction. The aim of the study was to investigate the renal function of the diabetic patients who visit the Clinical Analysis Laboratory (CAn-Lab) at the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. Materials and Methods: Demographic data as well as medical history were obtained through the administration of a questionnaire. Anthro-pometric measurements were taken and blood samples were analysed for glucose, uric acid, urea and creatinine. Data collected were analysed using SPSS version 16.0. Results: A total of 34 diabetic patients, aged from 40-77 y were recruited, 22 (64.7%) of them were males with mean age of 57.40 ± 11.8 y (±SD), while 12 (35.3%) were females with mean age of 58.17 ± 7.47 y. There was a statistically significant difference between the mean duration of the disease, as the females had longer duration, 12.50 ± 6.95 y, as compared to 7.32 ± 4.48 y in males (p=0.033). The mean plasma creatinine level in the females was 84.17 ± 54.73 ?mol/l. In the diabetic population, there was a positive correlation between age and plasma creatinine level, (r=0.375, p=0.029). In the female diabetics, there was a positive correlation between fasting blood sugar (FBS) and the measured metabolic end products (r>0.5, p<0.05), a positive correlation between body mass index (BMI) and uric acid (r=0.576, p=0.005) and a positive correlation between BMI and FBS (r= 0.625, p= 0.030). Conclusion: Our results on the parameters measured; show that the diabetic population was experiencing mild kidney dysfunction, compared to non-diabetic controls.

This activity encompasses two lab exercises. In the first lab exercise students examine various different types of microfossils (conodonts, foraminifera and radiolaria) under the microscope and try to make paleobiological inferences about them based on their morphological characteristics. Students also pick different conodont elements and different foraminiferal species from sediment samples. Two foraminiferal specimens are selected for scanning electron microscopy. I mount the specimens to a stub for the students. Then in the next lab period students are given a guided tour of the SEM lab and work with the technician to operate the SEM and take photographs of their specimens. They then use the photographs in conjunction with the Treastise of Invertebrate Paleontology to make a generic identification of their specimens.

Political Communications Lab  

NSDL National Science Digital Library

How do polls of public opinion and political behavior work exactly? Well, it's definitely a complex answer, and when you add the mix of how exactly these polls work when done in a less "traditional" fashion, such as with the Internet, things get even more complicated. Part of the mission of the Political Communication Lab at Stanford University is "to develop and administer experimental studies of public opinion and political behavior through the use of both on-line and traditional methods". The site is a rather fascinating one, as it contains a number of informative areas on work at the Lab and on the current presidential election campaign. One of the group's projects that is worth a look is the Voter Attention Share project, in which the Lab is tracking the total number of daily references to key election issues across national TV newscasts and the 80 most widely read daily newspapers from June 1 to Election Day. Visitors can also read about the group's other projects and listen to a talk on online polling by Professors James Fishkin and Shanto Iyengar.

Adapting Labs and Troubleshooting  

NSDL National Science Digital Library

A great deal of information is available on how children learn--brain research, multiple intelligence aspects, concrete versus abstract thinking, environmental stimuli, and so on--but one key feature can be gleaned from all of the studies, and that is the importance of hands-on learning. No matter what method students use to garner information, the learning process can be augmented with the inclusion of labs, activities, or simulations that mimic real-life experiences. This is especially true in the middle school science classroom.

Learning LabVIEW in Introductory Physics Labs  

NASA Astrophysics Data System (ADS)

LabVIEW is a graphical programming language, commonly used in physics and engineering research. ELVIS stands for Electronics Laboratory Virtual Instrumentation Suite. It is designed to replace all of the instruments commonly found on an electronics lab bench. Vernier Instruments sells adaptors which allow the Vernier sensors to be hooked into a breadboard, and controlled via a LabVIEW Virtual Instrument (VI.) While basic VI's exist for running the sensors through LabVIEW, more sophisticated VI's are necessary for plotting one quantity versus another. Introducing LabVIEW and ELVIS in the introductory physics laboratory course is useful for physics and engineering majors who will be ready to use the equipment more extensively in upper-level courses.

LifeLab  

NSDL National Science Digital Library

LifeLab is a Mac application for exploring John Conway's Game of Life and other cellular automata. CAs were first studied in the mid-1950s by Stanislaw Ulam and John von Neumann. The subject became much more widely known in 1970 when Life was described by Martin Gardner in his Scientific American column. Life is played on an arbitrary-sized grid of square cells. Each cell has two states: "dead" or "alive". The state of every cell changes from one "generation" to the next according to the states of its 8 nearest neighbors: a dead cell becomes alive (a "birth") if it has exactly 3 live neighbors; a live cell dies out if it has less than 2 or more than 3 live neighbors. The "game" of Life simply involves starting off with a pattern of live cells and watching it evolve.

Virtual Labs and Virtual Worlds  

NASA Astrophysics Data System (ADS)

Virtual Labs and Virtual Worlds Coastline Community College has under development several virtual lab simulations and activities that range from biology, to language labs, to virtual discussion environments. Imagine a virtual world that students enter online, by logging onto their computer from home or anywhere they have web access. Upon entering this world they select a personalized identity represented by a digitized character (avatar) that can freely move about, interact with the environment, and communicate with other characters. In these virtual worlds, buildings, gathering places, conference rooms, labs, science rooms, and a variety of other “real world” elements are evident. When characters move about and encounter other people (players) they may freely communicate. They can examine things, manipulate objects, read signs, watch video clips, hear sounds, and jump to other locations. Goals of critical thinking, social interaction, peer collaboration, group support, and enhanced learning can be achieved in surprising new ways with this innovative approach to peer-to-peer communication in a virtual discussion world. In this presentation, short demos will be given of several online learning environments including a virtual biology lab, a marine science module, a Spanish lab, and a virtual discussion world. Coastline College has been a leader in the development of distance learning and media-based education for nearly 30 years and currently offers courses through PDA, Internet, DVD, CD-ROM, TV, and Videoconferencing technologies. Its distance learning program serves over 20,000 students every year. sponsor Jerry Meisner

Lift-off process with bi-layer photoresist patterns for conformal-coated superhydrophilic pulsed plasma chemical vapor deposition-SiOx on SiCx for lab-on-a-chip applications  

NASA Astrophysics Data System (ADS)

In this work, a lift-off process with bi-layer photoresist patterns was applied to the formation of hydrophobic/hydrophilic micropatterns on practical polymer substrates used in healthcare diagnostic commercial products. The bi-layer photoresist patterns with undercut structures made it possible to peel the conformal-coated silicon oxide (SiOx) films from substrates. SiOx and silicon carbide (SiCx) layers were deposited by pulsed plasma chemical vapor deposition (PPCVD) method which can form roughened surfaces to enhance hydrophilicity of SiOx and hydrophobicity of SiCx. Microfluidic applications using hydrophobic/hydrophilic patterns were also demonstrated on low-cost substrates such as poly(ethylene terephthalate) (PET) and paper films.

Lunar Farside Radio Lab  

NASA Astrophysics Data System (ADS)

It is proposed that the Farside of the Moon should be protected legally against man-made radio pollution and uncontrolled exploitation. In fact, only by establishing a radiotelescope on the Farside of the Moon it will finally be possible to cope with the Radio Frequency Interference (RFI) that is now increasingly plaguing all of Radioastronomy, Bioastronomy and Search for Extraterrestrial Intelligence (SETI) Searches done from the surface of the Earth. It is suggested to partition the Farside into 3 sectors, each 60°wide, to ensurethe creation of a future “Lunar Farside Radio Lab” inside crater Daedalus (at 180°E) with our planned Radiotelescope (in practice a Phased Array),complete freedom to exploit the Nearside as well as the four Lagrangian points L1, L3, L4 and L5 of the Earth Moon system by allowing even some International Space Stations to be located there. It is also claimed, however, thatthe “opposite” Lagrangian point L2 should possibly be kept free of spacecrafts that would flood the Farside by the RFI they produce. Realistically, it might be difficult to comply with the latter request in view of the far-future development of a Space Base located there in order to depart towards the Asteroids and the Outer Planets at very reduced fuel consumption. A more reasonable request about any future space station located at the Earth Moon L2 point is thus that this future space station should be shielded to prevent its RFI from reaching the Farside of the Moon.A number of further astrophysical, astronautical and technical issues could just be highlighted in this study and deserve much more elaboration. To mention a few:the precise size of the “Quiet Cone” extending into space above the Farside of the Moon. Also, the experimental measurement of how quiet this Cone actually is by letting a radiometer orbit the Moon (see the web site www.rli.it);the mathematical modelling of the weak ionosphere of the Moon and its possible diffraction effects at very low frequencies. In other words, exploring the radio spectrum below 15 MHz (impossible from Earth) might open up a new era in Cosmology and Astrophysics in general;last, but not the least, the political problems involved with the future international exploitation of the Moon Farside. The IISL supported this author in this regard, but much more serious action should be undertaken, especially in conjunction with the United Nations. The protection of at least part of the Farside against wild commercial and military exploitation is regarded as the #1 priority of this study.

LabWrite: Transforming Lab Reports from Busy Work to Meaningful Learning Opportunities  

NSDL National Science Digital Library

Lab reports are the dreaded assignments of the laboratory course. Students dislike them, because they can be tedious and time-consuming. Instructors dislike them, because they significantly increase the grading load. For this reason, lab reports are often omitted or replaced by alternatives such as responses to lab questions, fill-in-the-blank lab manual exercises, or lab quizzes. Despite its negative associations, the lab reports can help students learn how to write scientifically using an authentic scientific writing genre that allows them to formulate hypotheses, make inferences based on findings, and develop scientific arguments--cornerstones of scientific literacy. Students are also more apt to revisit the lab procedure and reflect on the experiment when writing lab reports. Reflecting on the lab in conjunction with putting the lab in their own words provides students a very effective tool for learning the science of the lab.

Transportation Engineering: Online Lab Manual  

NSDL National Science Digital Library

The University of Idaho hosts this outstanding collection of educational materials and laboratories related to transportation engineering. The topics introduced on the site are intended to supplement a junior-level course on the subject and are commonly viewed as "the most important ones that civil engineering graduates need to understand." Each chapter of the lab manual contains detailed theory and example problems. The lab exercises, however, will probably only serve to emphasize the most important concepts for students whose teachers are not directly incorporating them into the curricula.

Measurement system for high-sensitivity LIBS analysis using ICCD camera in LabVIEW environment  

NASA Astrophysics Data System (ADS)

A measurement system based on ultrafast (up to 10 ns time resolution) intensified CCD detector ``Nanogate-2V'' (Nanoscan, Russia) was developed for high-sensitivity analysis by Laser-Induced Breakdown Spectrometry (LIBS). LabVIEW environment provided a high level of compatibility with variety of electronic instruments and an easy development of user interface, while Visual Studio environment was used for creation of LabVIEW compatible dll library with the use of ``Nanogate-2V'' SDK. The program for camera management and laser-induced plasma spectra registration was created with the use of Call Library Node in LabVIEW. An algorithm of integration of the second device ADC ``PCI-9812'' (ADLINK) to the measurement system was proposed and successfully implemented. This allowed simultaneous registration of emission and acoustic signals under laser ablation. The measured resolving power of spectrometer-ICCD system was equal to 12000 at 632 nm. An electron density of laser plasma was estimated with the use of H-? Balmer line. Steel spectra obtained at different delays were used for selection of the optimal conditions for manganese analytical signal registration. The feature of accumulation of spectra from several laser pulses was shown. The accumulation allowed reliable observation of silver signal at 328.07 nm in the LIBS spectra of soil (CAg = 4.5 ppm). Finally, the correlation between acoustic and emission signals of plasma was found. Thus, technical possibilities of the developed LIBS system were demonstrated both for plasma diagnostics and analytical measurements.

Dark-current-free laser-plasma acceleration in blowout regime using nonlinear plasma lens  

NASA Astrophysics Data System (ADS)

It is demonstrated that a thin dense plasmas lab (lens), placed before a multi-centimeter-length, low-density plasma (accelerator), overfocuses an incident petawatt laser pulse at a controlled location inside the accelerator, creating an expanding electron density bubble that traps plasma electrons over a brief time interval. As soon as the pulse stabilizes and self-guiding begins, the bubble stabilizes and transforms into the ?rst (non-broken) bucket of a conventional three-dimensional nonlinear plasma wave, eliminating any chance for further injection. A well collimated, quasi-monoenergetic electron bunch with a zero low-energy background further accelerates to a multi-GeV energy.

Rock cycle in chocolate lab  

NSDL National Science Digital Library

In this lab students receive two small blocks (1 cm3) of chocolate (white and dark), and follow it through the entire rock cycle. The chocolate blocks are melted on a hot plate, with different melting temperatures and rheologies due to compositional differences. The "magma" is then cooled either slowly or quickly, and the resulting textures are examined and compared to granite and basalt hand samples. The "igneous" chocolate is then ground and abraded to show erosion, and the eroded material is pressure-lithified to form "sedimentary" chocolate. The sedimentary chocolate then undergoes greater pressure to mimic metamorphism, and additional heat re-melts the chocolate back into magma. Students compare the chocolate "rocks" in each of these stages with real rock samples. The final assignment is to describe the "life story" of complex conglomerate rock sample. The lab is a bit messy and takes a bit of preparation, but students come away with a significantly better understanding of the rock cycle as a whole and each of its component parts.

Lab Report Writing (And Teaching!) Made Easy  

NSDL National Science Digital Library

This paper reports on a project to improve students ability to write better lab reports and assist teaching assistants (TAs) in grading reports in a consistent manner. A lab report teaching system was developed that includes lab report templates, teaching assistant instructions, grading rubrics, examples, peer review materials and instructions, and recommendations for quickly providing student feedback (grading). These materials were developed for project-based labs across the electrical engineering curriculum and utilize methods to write weekly lab updates that are combined into a final lab report, mimicking methods commonly used in industry. The technical writing information was adapted to all levels of complexity to help students from freshman through senior years. The system begins with instruction on writing very basic reports, and builds each year on previous knowledge and practices, to prepare students to later write complex reports. This system is designed to improve students understanding of labs (by writing to learn) in addition to preparing them for the communication intensive workplace. The amount of time spent grading such reports is often a primary concern, as this is commonly given as a reason for not requiring advanced writing assignments in engineering classes. Detailed guidelines and grading rubrics are included in this manual to instruct TAs on better and more consistent grading techniques. Guidelines for checking both lab books and formal lab reports help improve TA training and grading consistency, reducing student complaints. Although this system was designed for an electrical engineering program, it can also be adapted to other technical fields and used for various scientific lab reports.

Jefferson Lab's Trim Card II  

SciTech Connect

Jefferson Lab's Continuous Electron Beam Accelerator Facility (CEBAF) uses Trim Card I power supplies to drive approximately 1900 correction magnets. These trim cards have had a long and illustrious service record. However, some of the employed technology is now obsolete, making it difficult to maintain the system and retain adequate spares. The Trim Card II is being developed to act as a transparent replacement for its aging predecessor. A modular approach has been taken in its development to facilitate the substitution of sections for future improvements and maintenance. The resulting design has been divided into a motherboard and 7 daughter cards which has also allowed for parallel development. The Trim Card II utilizes modern technologies such as a Field Programmable Gate Array (FPGA) and a microprocessor to embed trim card controls and diagnostics. These reprogrammable devices also provide the versatility to incorporate future requirements.

Integrating Robotic Observatories into Astronomy Labs  

NASA Astrophysics Data System (ADS)

The University of St. Thomas (UST) and a consortium of five local schools is using the UST Robotic Observatory, housing a 17' telescope, to develop labs and image processing tools that allow easy integration of observational labs into existing introductory astronomy curriculum. Our lab design removes the burden of equipment ownership by sharing access to a common resource and removes the burden of data processing by automating processing tasks that are not relevant to the learning objectives.Each laboratory exercise takes place over two lab periods. During period one, students design and submit observation requests via the lab website. Between periods, the telescope automatically acquires the data and our image processing pipeline produces data ready for student analysis. During period two, the students retrieve their data from the website and perform the analysis. The first lab, 'Weighing Jupiter,' was successfully implemented at UST and several of our partner schools. We are currently developing a second lab to measure the age of and distance to a globular cluster.

Labs not in a lab: A case study of instructor and student perceptions of an online biology lab class  

NASA Astrophysics Data System (ADS)

Distance learning is not a new phenomenon but with the advancement in technology, the different ways of delivering an education have increased. Today, many universities and colleges offer their students the option of taking courses online instead of sitting in a classroom on campus. In general students like online classes because they allow for flexibility, the comfort of sitting at home, and the potential to save money. Even though there are advantages to taking online classes, many students and instructors still debate the effectiveness and quality of education in a distant learning environment. Many universities and colleges are receiving pressure from students to offer more and more classes online. Research argues for both the advantages and disadvantages of online classes and stresses the importance of colleges and universities weighing both sides before deciding to adopt an online class. Certain classes may not be suitable for online instruction and not all instructors are suitable to teach online classes. The literature also reveals that there is a need for more research on online biology lab classes. With the lack of information on online biology labs needed by science educators who face the increasing demand for online biology labs, this case study hopes to provide insight into the use of online biology lab classes and the how students and an instructor at a community college in Virginia perceive their online biology lab experience as well as the effectiveness of the online labs.

Jefferson Lab's Distributed Data Acquisition  

SciTech Connect

Jefferson Lab's Continuous Electron Beam Accelerator Facility (CEBAF) occasionally experiences fast intermittent beam instabilities that are difficult to isolate and result in downtime. The Distributed Data Acquisition (Dist DAQ) system is being developed to detect and quickly locate such instabilities. It will consist of multiple Ethernet based data acquisition chassis distributed throughout the seven-eights of a mile CEBAF site. Each chassis will monitor various control system signals that are only available locally and/or monitored by systems with small bandwidths that cannot identify fast transients. The chassis will collect data at rates up to 40 Msps in circular buffers that can be frozen and unrolled after an event trigger. These triggers will be derived from signals such as periodic timers or accelerator faults and be distributed via a custom fiber optic event trigger network. This triggering scheme will allow all the data acquisition chassis to be triggered simultaneously and provide a snapshot of relevant CEBAF control signals. The data will then be automatically analyzed for frequency content and transients to determine if and where instabilities exist.

Lab-on-a-Chip  

NASA Technical Reports Server (NTRS)

Labs on chips are manufactured in many shapes and sizes and can be used for numerous applications, from medical tests to water quality monitoring to detecting the signatures of life on other planets. The eight holes on this chip are actually ports that can be filled with fluids or chemicals. Tiny valves control the chemical processes by mixing fluids that move in the tiny channels that look like lines, connecting the ports. Scientists at NASA's Marshall Space Flight Center (MSFC) in Huntsville, Alabama designed this chip to grow biological crystals on the International Space Station. Through this research, they discovered that this technology is ideally suited for solving the challenges of the Vision for Space Exploration. For example, thousands of chips the size of dimes could be loaded on a Martian rover looking for biosignatures of past or present life. Other types of chips could be placed in handheld devices used to monitor microbes in water or to quickly conduct medical tests on astronauts. (NASA/MSFC/D.Stoffer)

Hydrogen-Oxygen Reaction Lab  

NSDL National Science Digital Library

This lab exercise exposes students to a potentially new alternative energy source—hydrogen gas. Student teams are given a hydrogen generator and an oxygen generator. They balance the chemical equation for the combustion of hydrogen gas in the presence of oxygen. Then they analyze what the equation really means. Two hypotheses are given, based on what one might predict upon analyzing the chemical equation. Once students have thought about the process, they are walked through the experiment and shown how to collect the gas in different ratios. By trial and error, students determine the ideal combustion ratio. For both volume of explosion and kick generated by explosion, they qualitatively record results on a 0-4 scale. Then, students evaluate their collected results to see if the hypotheses were correct and how their results match the theoretical equation. Students learn that while hydrogen will most commonly be used for fuel cells (no combustion situation), it has been used in rocket engines (for which a tremendous combustion occurs).

RoboLab and virtual environments  

NASA Astrophysics Data System (ADS)

A useful adjunct to the manned space station would be a self-contained free-flying laboratory (RoboLab). This laboratory would have a robot operated under telepresence from the space station or ground. Long duration experiments aboard RoboLab could be performed by astronauts or scientists using telepresence to operate equipment and perform experiments. Operating the lab by telepresence would eliminate the need for life support such as food, water and air. The robot would be capable of motion in three dimensions, have binocular vision TV cameras, and two arms with manipulators to simulate hands. The robot would move along a two-dimensional grid and have a rotating, telescoping periscope section for extension in the third dimension. The remote operator would wear a virtual reality type headset to allow the superposition of computer displays over the real-time video of the lab. The operators would wear exoskeleton type arms to facilitate the movement of objects and equipment operation. The combination of video displays, motion, and the exoskeleton arms would provide a high degree of telepresence, especially for novice users such as scientists doing short-term experiments. The RoboLab could be resupplied and samples removed on other space shuttle flights. A self-contained RoboLab module would be designed to fit within the cargo bay of the space shuttle. Different modules could be designed for specific applications, i.e., crystal-growing, medicine, life sciences, chemistry, etc. This paper describes a RoboLab simulation using virtual reality (VR). VR provides an ideal simulation of telepresence before the actual robot and laboratory modules are constructed. The easy simulation of different telepresence designs will produce a highly optimum design before construction rather than the more expensive and time consuming hardware changes afterwards.

Amazing plasmas  

NSDL National Science Digital Library

A space weather site offers this tutorial about the state of matter called plasma. Animations, two games, and numerous enlargeable graphics are included in the tutorial. It presents information about what plasma is and where it is naturally found. The tutorial explains that understanding plasma and how it interacts with electric and magnetic fields is central to understanding much about our universe. In addition, one section of the tutorial discusses experimental fusion reactors in which man-made plasmas are used on earth. Plasma is the main type of matter in the universe, but it rarely occurs naturally on Earth because of the world's relatively cool temperatures. Copyright 2005 Eisenhower National Clearinghouse

Optical Analysis of Plasma Ball Filaments  

NASA Astrophysics Data System (ADS)

Optical methods were used to study the properties of a commercial plasma ball. Using spectrometry, the gas composition of the plasma ball was analyzed. Spectra of known gases were compared with the plasma ball spectrum, confirming the presence of Neon and Xenon. The spectra indicate that faint amounts of Nitrogen may also be present. Photomultiplier tubes were used to measure the radial velocity of filaments in the plasma ball. Digital oscilloscope traces produced with the photomultiplier tubes show that the filaments propagate radially at an average velocity on the order of 10,000 m/s. Furthermore, these traces suggest that that the radial velocity decreases with increasing distance from the electrode. A hotwired commercial plasma ball, with connections for a pulse generator and Variac has been built, allowing for the study of filament velocity at different operating voltages and frequencies. A custom plasma ball whose parameters, such as gas mixture, pressure, electrode configuration, and applied voltage waveform can be varied, has also been constructed. Analysis of the custom plasma ball will give further insight to how such parameters affect the plasma ball's filament formation and behavior. Initial results will be presented. Ultimately, this custom plasma ball, along with the methods used to measure its properties, will be incorporated into an undergraduate physics lab.

Dusty plasmas  

SciTech Connect

This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The objective of this project has been to develop a fundamental understanding of dusty plasmas at the Laboratory. While dusty plasmas are found in space in galactic clouds, planetary rings, and cometary tails, and as contaminants in plasma enhanced fabrication of microelectronics, many of their properties are only partially understood. Our work has involved both theoretical analysis and self-consistent plasma simulations to understand basic properties of dusty plasmas related to equilibrium, stability, and transport. Such an understanding can improve the control and elimination of plasma dust in industrial applications and may be important in the study of planetary rings and comet dust tails. We have applied our techniques to the study of charging, dynamics, and coagulation of contaminants in plasma processing reactors for industrial etching and deposition processes and to instabilities in planetary rings and other space plasma environments. The work performed in this project has application to plasma kinetics, transport, and other classical elementary processes in plasmas as well as to plasma waves, oscillations, and instabilities.

LETTER: Effect of plasma rotation on the beam-driven current  

NASA Astrophysics Data System (ADS)

In a rotating plasma, with co-neutral beam injection (NBI), the Doppler shift of the NBI particles, as viewed in the frame of the plasma, can result in a significant reduction in the beam-driven (Ohkawa) current when the rotation is strong (i.e. with rotational Mach numbers, M >= 0.5). The correction applies to the toroidal fast ion current calculated for a non-rotating plasma and is independent of the normal Zeff and electron trapping terms. A simple analytical model is presented to estimate the magnitude of the effect for plasmas with arbitrary toroidal rotation and the conditions where this is important have been identified. This model has been compared with the results from existing Monte Carlo neutral beam codes and found to reproduce their results. The important parameters in this problem are the ratio, \\rho^{Lab} = v_{f0}^Lab/v_crit , of the NBI injection particle velocity (in the laboratory frame) to the critical velocity of the plasma, and the ratio ?phi = vphi/vcrit which is related to the rotational Mach number. A phase plot in dimensionless (?Lab, ?phi) space is presented which enables the fast ion current drive efficiencies to be compared for different tokamaks. For strongly rotating plasmas, the degradation in fast ion current efficiency is significant for ?Lab <= 1. However, when ?Lab is larger than this, the degradation in fast ion current drive is less severe. Approaches to improve the fast ion current drive efficiency are briefly discussed.

Characterization of silicon etching in synchronized pulsed plasma  

NASA Astrophysics Data System (ADS)

Pulsed plasmas have been proposed many years ago by research labs and have shown a great potential for etch process improvement. Nevertheless, they have been introduced in manufacturing only recently and the exact characteristics of pulsed plasmas in industrial scale reactors are hardly known. In this paper, we have characterized silicon etching in pulsed HBr/O2 plasmas using advanced plasma diagnostics (mass spectrometry and ion flux probe) in a 300 mm industrial reactor. We show that pulsing the plasma at low duty cycle reduces the gas molecules dissociation and plasma temperature, as well as the flux of energetic ions to the wafer. The ions during silicon etching are mostly silicon-containing ions that are heavier at low duty cycle. Silicon patterns etched using pulsed plasmas present improved profiles, which is attributed to more uniform passivation layers at low duty cycle.

Supplemental Guidelines, JCE Lab-Experiment Manuscripts  

NASA Astrophysics Data System (ADS)

These guidelines supplement the Guide to Submissions (published in J. Chem. Educ. 2000, 77, 29-30 and at http://jchemed.chem.wisc.edu/Journal/Authors/ Guidelines.html or available on request from the JCE editorial office). Manuscripts that describe laboratory experiments should first follow the Guide to Submissions and then apply these Supplemental Guidelines. Rationale JCE receives many submissions that describe laboratory experiments. The broad range of experiments readers can find each month is one of our most important features. These supplemental guidelines have been designed to make published laboratory experiments as useful as possible to readers. They are based on four fundamental ideas:

  • peer review of a lab-experiment manuscript should be based to a large degree on the written and technology-based materials used by students in the laboratory, not just on a description of those materials;
  • JCE should print the information a reader needs to decide whether to try to use the experiment; this includes information about possible safety hazards;
  • readers who decide to use a lab should be able to adapt it to their circumstances quickly and easily;
  • detailed information, including student materials, should be available to adopters of an experiment in a format that is modifiable and easily adapted for use by faculty, students, and support staff.
To support these goals we require that a manuscript that describes a laboratory experiment must consist of a Lab Summary and Lab Documentation. (Each of these is described in detail below.) If, after peer review, a lab-experiment manuscript is published, only the Lab Summary will be printed in JCE. The Abstract, the Lab Summary, and all Lab Documentation will be published via JCE Online. Lab Documentation is placed on the Web as PDF files that can be displayed and printed by Acrobat Reader, and as Word or Word Perfect files that can be edited by those who adopt a lab. Those without Web access can request printed copies of all materials related to a particular experiment. We will provide these via U.S. Postal Service at cost. Literature Search Those who plan to submit a lab experiment should first search titles in the JCE Index online at http://jchemed.chem.wisc.edu/Journal/Search/ index.html to make certain that a similar experiment has not already appeared in the Journal. Related experiments should be cited in the Literature Cited section of the manuscript; if a previously published lab is very similar, some explanation should be given as to why the new manuscript provides information not already available to readers. Prospective authors should also search the Annotated List of Laboratory Experiments, a keyworded, computer-searchable database compiled by Stanley Bunce, James Zubrick, and members of the Division of Chemical Education Committee on Project ChemLab. It is currently available for IBM PC from Project SERAPHIM for downloading at http://ice.chem.wisc.edu/SERAPHIM/PC_Files/ PC2001.zip. It is also available as a PDF file. Lab Summary The Lab Summary must be accompanied by an abstract, keywords, and Lab Documentation. It will usually include literature cited and may include tables and figures. (See the JCE Guide to Submissions for more details.) The Lab Summary should be no longer than two Journal pages (about 1500 words). The Lab Summary should enable a reader to decide whether the experiment described would be suitable for a local course or program. It should briefly give a rationale for adopting the experiment and an indication of the course or level where the experiment fits into the curriculum. It should describe the procedures, techniques, facts, and concepts students will learn. It should explain how and why the experiment helps the students learn and give typical results obtained by students who have done the experiment. It should list equipment, chemicals, and/or instruments that are not expected to be available in a typical chemistry department. The Lab Summary must inc

Hands-on experiments with electronic devices have been recognized as an important element in the field of engineering to help students get familiar with theoretical concepts and practical tasks. The continuing increase the student number, costly laboratory equipment, and laboratory maintenance slow down the physical lab efficiency. As information technology continues to evolve, the Internet has become a common media in modern education. Internetbased remote laboratory can solve a lot of restrictions, providing hands-on training as they can be flexible in time and the same equipment can be shared between different students. This article describes an on-going remote hands-on experimental radio modulation, network and mobile applications lab project "eComLab".

[Plasma cells].  

PubMed

Plasma cells are specialized terminally differentiated B cells that synthesize and secrete antibodies to maintain humoral immunity. By the production of pathogenic antibodies, plasma cells contribute to the development of many conditions, such as autoimmune disorders, transplant rejection and allergies. Two different plasma cell compartments can independently generate different types of pathogenic antibodies: (1) short-lived plasmablasts (proliferating precursors of mature plasma cells) and plasma cells, which live only as long as B cells are activated. Consequently, these cells cause disease flares that respond to immunosuppressive drugs and B cell targeting therapies. (2) Long-lived non-proliferating memory plasma cells, which survive in niches in bone marrow and inflamed tissues for months, years or a lifetime independent of B or T cell help or antigen contact. Because they do not respond to immunosuppressants or treatment targeting B cells, they are responsible for refractory chronic conditions. Therefore, long-lived memory plasma cells in particular have emerged as important therapeutic targets and strategies to target these cells are discussed in this article. So far long-lived plasma cells can only be depleted by immunoablative therapy with antithymocyte globulin in the setting of stem cell transplantation or by treatment with proteasome inhibitors approved for multiple myeloma. These strategies provide options for treating refractory autoantibody-mediated diseases. One interesting approach aims at an antigen-specific elimination of target plasma cells without depleting the protective plasma cells responsible for maintaining humoral immunity. PMID:25616773

LabVIEW for Admittance Spectroscopy Automation  

NASA Astrophysics Data System (ADS)

Admittance spectroscopy (AS) and capacitance-voltage (C-V) measurements have long been characterization tools used to study properties of deep level defects in semiconductor devices. Measurements of conductance and capacitance of semiconductor devices are made typically as a function of temperature, voltage, and voltage signal frequency. To fully automate the system for data acquisition, LabVIEW, a virtual graphical programming language developed by National Instruments, is used to interface a computer with the measurement instruments. In this paper, the LabVIEW modules used and highlights of data from wide bandgap semiconductor devices will be presented.

Improving the Quality of Lab Reports by Using Them as Lab Instructions  

NASA Astrophysics Data System (ADS)

Lab exercises are quite popular in teaching science. Teachers have numerous goals in mind when teaching science laboratories. Nevertheless, empirical research draws a heterogeneous picture of the benefits of lab work. Research has shown that it does not necessarily contribute to the enhancement of practical abilities or content knowledge. Lab activities are frequently based on recipe-like, step-by-step instructions ("cookbook style"), which do not motivate students to engage cognitively. Consequently, students put the emphasis on "task completion" or "manipulating equipment."2

Earth plasmas  

NSDL National Science Digital Library

Fusion is the focus of this section of a tutorial about plasma, one of the four states of matter. This section deals with plasmas on Earth. There is little naturally-occurring plasma here because of the Earth's relatively cool (by universe standards) temperature, but human-made plasma is produced for industry and research purposes. The section explores the use of plasmas in experimental fusion reactors, pointing out three categories of significant unresolved issues that stand in the way of fusion becoming a viable energy source. The use of electromagnets to confine plasmas is discussed. Enlargeable images of fusion reactors are provided, and an explanation of the difference between fission and fusion is supplemented by animations of the two reaction types.

Plasma in the Synthesis of Nanoparticles  

NASA Astrophysics Data System (ADS)

Development of nanotechnology, specifically the production of carbon nanotubes, may be integral to innovation in an array of fields, from textiles to electronics. The structure of carbon nanotubes affords for the creation of materials with exceptional strength and conductivity. At present, scientists rely on ``cut-and-try'' methods to perfect the plasma synthesis, leaving an interface gap between plasma and material sciences. As a result, methods of producing carbon nanotubes are expensive and length is difficult to standardize. Therefore, the development of a method to produce carbon nanotubes efficiently and in uniform sizes is of great interest. To elucidate the role of plasma in the synthesis of nanoparticles, Princeton Plasma Physics Lab is developing a Plasma-Based Nano Laboratory (PBNL). The PBNL houses an Electron Diffusion Gauge Experiment (EDGE) as well as a Nanotube Arc Discharge Experiment (NADE) with the purpose of investigating plasma-nanoparticle interaction. The NADE studies the ability to control the diameter and length of nanotube formation through a set of experimental parameters. In addition, the potential to increase nanotube length will be studied. PPPL's expertise on plasma science could be critically valuable to the successful development of highly efficient and low cost plasma-based techniques, which have the potential to increase accessibility of nanotubes, and propel further innovation rooted in nanotechnology.

The system has special microscopes and imaging systems, so scientists can process and study different types of fluid, chemical, and medical tests conducted on chips. For example, researchers have examined fluorescent bacteria as it flows through the chips' fluid channels or microfluidic capillaries. Researchers at NASA's Marshall Space Flight Center (MSFC) in Huntsville, Alabama, have been studying how the lab-on-a-chip technology can be used for microbial detection, water quality monitoring, and detecting biosignatures of past or present life on Mars. The Marshall Center team is also collaborating with scientists at other NASA centers and at universities to develop custom chip designs for not only space applications, but for many Earth applications, such as for detecting deadly microbes in heating and air systems.

NASA GeneLab Concept of Operations  

NASA Technical Reports Server (NTRS)

NASA's GeneLab aims to greatly increase the number of scientists that are using data from space biology investigations on board ISS, emphasizing a systems biology approach to the science. When completed, GeneLab will provide the integrated software and hardware infrastructure, analytical tools and reference datasets for an assortment of model organisms. GeneLab will also provide an environment for scientists to collaborate thereby increasing the possibility for data to be reused for future experimentation. To maximize the value of data from life science experiments performed in space and to make the most advantageous use of the remaining ISS research window, GeneLab will apply an open access approach to conducting spaceflight experiments by generating, and sharing the datasets derived from these biological studies in space.Onboard the ISS, a wide variety of model organisms will be studied and returned to Earth for analysis. Laboratories on the ground will analyze these samples and provide genomic, transcriptomic, metabolomic and proteomic data. Upon receipt, NASA will conduct data quality control tasks and format raw data returned from the omics centers into standardized, annotated information sets that can be readily searched and linked to spaceflight metadata. Once prepared, the biological datasets, as well as any analysis completed, will be made public through the GeneLab Space Bioinformatics System webb as edportal. These efforts will support a collaborative research environment for spaceflight studies that will closely resemble environments created by the Department of Energy (DOE), National Center for Biotechnology Information (NCBI), and other institutions in additional areas of study, such as cancer and environmental biology. The results will allow for comparative analyses that will help scientists around the world take a major leap forward in understanding the effect of microgravity, radiation, and other aspects of the space environment on model organisms. These efforts will speed the process of scientific sharing, iteration, and discovery.

Plasma Molding over Surface Topography: IED and IAD over Steps  

NASA Astrophysics Data System (ADS)

Plasma molding over surface topography finds applications in MEMS microfabrication, plasma extraction through grids, and plasma contact with internal reactor parts (e.g., wafer chuck edge). The flux, energy and angular distributions of ions incident on the target are of primary importance in these applications. These quantities depend critically on the shape of the meniscus (plasma-sheath boundary) formed over the surface topography. We have developed a 2-D simulation tool to calculate the flux, energy and angular distribution of ions (and fast neutrals) impinging on surface topography in contact with a high density plasma. Plasma molding over a step has been analyzed in detail. Simulation results will be compared to experimental data as a function of distance from the step obtained at Sandia National Labs.

Our research highlights four novel insights: first, Living Labs function at the low and mid level innovation strata; second, Living Labs are technologically agnostic; third, Living Labs use context based experience to surface new, socially constructed meanings for products and services; and finally, Living Labs are equally focused on exploration and exploitation.

Jefferson Lab was created in 1984 and started operating in about 1996. 2011 is an appropriate time to try to take a look at the results that have appeared, what has been learned, and what has been exciting for our scientific community. Rather than attempt to construct a coherent view with a single author or at least a small number, we have, instead, invited small groups of people who have been intimately involved in the work itself to make contributions. These people are accelerator experts, experimentalists and theorists, staff and users. We have, in the main, sought reviews of the actual sub-fields. The primary exception is the first paper, which sets the scene as it was, in one person's view, at the beginning of Jefferson Lab. In reviewing the material as it appeared, I was impressed by the breadth of the material. Major advances are documented from form factors to structure functions, from spectroscopy to physics beyond the standard model of nuclear and particle physics. Recognition of the part played by spin, the helicities of the beams, the polarizations of the targets, and the polarizations of final state particles, is inescapable. Access to the weak interaction amplitudes through measurements of the parity violating asymmetries has led to quantification of the strange content of the nucleon and the neutron radius of lead, and to measurements of the electroweak mixing angle. Lattice QCD calculations flourished and are setting the platform for understanding of the spectroscopy of baryons and mesons. But the star of the game was the accelerator. Its performance enabled the physics and also the use of the technology to generate a powerful free electron laser. These important pieces of Jefferson Lab physics are given their place. As the third Director of Jefferson Lab, and on behalf of the other physicists and others presently associated with the lab, I would like to express my admiration and gratitude for the efforts of the directors, chief scientists, associate directors, physicists, engineers, technicians and administrators who made it all possible. In sum, we should celebrate the science that Jefferson Lab has realized in this, its first long decade of physics.

Are Virtual Labs as Effective as Hands-on Labs for Undergraduate Physics? A Comparative Study at Two Major Universities  

NASA Astrophysics Data System (ADS)

Most physics professors would agree that the lab experiences students have in introductory physics are central to the learning of the concepts in the course. It is also true that these physics labs require time and money for upkeep, not to mention the hours spent setting up and taking down labs. Virtual physics lab experiences can provide an alternative or supplement to these traditional hands-on labs. However, physics professors may be very hesitant to give up the hands-on labs, which have been such a central part of their courses, for a more cost and time-saving virtual alternative. Thus, it is important to investigate how the learning from these virtual experiences compares to that acquired through a hands-on experience. This study evaluated a comprehensive set of virtual labs for introductory level college physics courses and compared them to a hands-on physics lab experience. Each of the virtual labs contains everything a student needs to conduct a physics laboratory experiment, including: objectives, background theory, 3D simulation, brief video, data collection tools, pre- and postlab questions, and postlab quiz. This research was conducted with 224 students from two large universities and investigated the learning that occurred with students using the virtual labs either in a lab setting or as a supplement to hands-on labs versus a control group of students using the traditional hands-on labs only. Findings from both university settings showed the virtual labs to be as effective as the traditional hands-on physics labs.

Chaos Lab: An Orderly Pursuit of Disorder  

NSDL National Science Digital Library

Chaos Lab is a great piece of software that teaches users about fractals and chaos theory. The menu-driven interface is extremely easy to use; however, a significant drawback of the software is its poor documentation. This can make experimenting with the settings more fun, but it would be helpful to have better explanations of the more obscure functions. What Chaos Lab lacks in documentation, it makes up for in the remarkable visual representations of famous fractals. The Mandelbrot and Julia sets can be explored with simple zooming tools, equation definitions, and brilliant color selections. Many more options are available, making the program a powerful educational tool in a small package. It is a free download.

Measuring the Gravity Field: "The Stairwell Lab"  

NSDL National Science Digital Library

Students will prepare for the lab by reading a description of gravity meter operation. After a brief quiz, the students will assemble with the meter in the stairwell of the building and measure the elevation to each level. After this, they will take multiple measurements on each level going up the stairwell, and then repeat the measurements on the way down, making sure to record the data values and the time. They will then convert the raw data to mGal using the conversion factor from the meter, and then use the data from the lower level to correct for drift. The corrected data are then plotted vs. elevation, a slope determined and the slope compared to the elevation correction term. The students will then write a lab report describing the procedure, presenting the data and their analysis, example calculations and their results. Has minimal/no quantitative component

Fluvial Transport of Bones Lab Exercise  

NSDL National Science Digital Library

The lab starts with a short lecture on the scientific method, after which students observe the results of a flume run that includes skeletal clasts. They form hypotheses about how bone clasts (or any clast for that matter) move and are deposited by a flow, then the students test their hypotheses by running a flume trial. The hypothesis tests take place in small groups (3-5 students), and the lab ends with homework where students use the information they learned from their hypothesis tests to interpret a fossil assemblage. As such, this is a wonderful activity for introductory geology classes, could be used effectively with minor adjustments for advanced paleontology, taphonomy, and forensic physical anthropology classes.

Jefferson Lab Data Acquisition Run Control System  

SciTech Connect

A general overview of the Jefferson Lab data acquisition run control system is presented. This run control system is designed to operate the configuration, control, and monitoring of all Jefferson Lab experiments. It controls data-taking activities by coordinating the operation of DAQ sub-systems, online software components and third-party software such as external slow control systems. The main, unique feature which sets this system apart from conventional systems is its incorporation of intelligent agent concepts. Intelligent agents are autonomous programs which interact with each other through certain protocols on a peer-to-peer level. In this case, the protocols and standards used come from the domain-independent Foundation for Intelligent Physical Agents (FIPA), and the implementation used is the Java Agent Development Framework (JADE). A lightweight, XML/RDF-based language was developed to standardize the description of the run control system for configuration purposes.

Harmonic Lasing Characterization at Jefferson Lab  

SciTech Connect

Harmonic lasing is normally suppressed because of lasing at the fundamental wavelength. It can, however, be achieved by using any of several methods that suppress fundamental lasing. In this paper we discuss two methods used at Jefferson Lab. The first is to use the characteristics of dielectric coatings to allow harmonic lasing at cavity lengths longer than the synchronous length for the fundamental. The second is to use a dielectric coating that has little reflectivity at the fundamental. This allows us to directly compare fundamental and harmonic lasing with the same optical resonator and electron beam. We present measurement carried out at Jefferson Lab using the IR Upgrade FEL operating at 0.53, 0.94, 1.04, 1.6, and 2.8 microns in which both schemes are used to produce lasing at both the 3rd and 5th harmonic of the fundamental.

Depositional Environments and Geologic History Labs  

NSDL National Science Digital Library

The goal of this pair of labs is for the students to learn to apply rock and fossil identification skills to determining rock formations, sedimentary depositional environments, age ranges, and, ultimately, to writing a geologic history of a sequence of rocks from Bryce, Zion, and Grand Canyons. During the first of the two labs, the students learn to make fossil and sedimentary structures identifications. They add these skills to their rock and mineral identification skills to make interpretations of the sedimentary environments along a generalized profile from terrestrial to offshore locations. During the second lab, they apply these skills to a sequence of rocks from the southwestern U.S. to interpret the environmental changes that have occurred over time. They also begin to learn how to use fossils to determine age ranges for these changing events. Once they put together all of their data, they construct a stratigraphic column and piece together a written narrative of the geologic history of the area. The students work in groups to collect their data and determine their stratigraphy. They write their geologic histories individually. The students learn how to apply their skills and knowledge to make interpretations and also learn how to support their determinations with data.

Studies of the ablated plasma from experimental plasma gun disruption simulations  

SciTech Connect

Extensive simulations of Tokamak disruptions have provided a picture of material erosion that is limited by the transfer of energy from the incident plasma to the armor solid surface through a dense vapor shield. Radiation spectra were recorded in the VUV and in the visible at the Efremov Laboratories on VIKA using graphite targets. The VUV data were recorded with a Sandia Labs transmission grating spectrograph, covering 1--40 nm. Plasma parameters were evaluated with incident plasma energy densities varying from 1--10 kJ/cm{sup 2}. A second transmission grating spectrograph was taken to 2MK-200 at TRINITI to study the plasma-material interface in magnetic cusp plasma. Target materials included POCO graphite, ATJ graphite, boron nitride, and plasma-sprayed tungsten. Detailed spectra were recorded with a spatial resolution of {approximately}1 mm resolution. Time-resolved data with 40--200 ns resolution was also recorded. The data from both plasma gun facilities demonstrated that the hottest plasma region was sitting several millimeters above the armor tile surface.

Welding arc plasma physics  

NASA Technical Reports Server (NTRS)

The problems of weld quality control and weld process dependability continue to be relevant issues in modern metal welding technology. These become especially important for NASA missions which may require the assembly or repair of larger orbiting platforms using automatic welding techniques. To extend present welding technologies for such applications, NASA/MSFC's Materials and Processes Lab is developing physical models of the arc welding process with the goal of providing both a basis for improved design of weld control systems, and a better understanding of how arc welding variables influence final weld properties. The physics of the plasma arc discharge is reasonably well established in terms of transport processes occurring in the arc column itself, although recourse to sophisticated numerical treatments is normally required to obtain quantitative results. Unfortunately the rigor of these numerical computations often obscures the physics of the underlying model due to its inherent complexity. In contrast, this work has focused on a relatively simple physical model of the arc discharge to describe the gross features observed in welding arcs. Emphasis was placed of deriving analytic expressions for the voltage along the arc axis as a function of known or measurable arc parameters. The model retains the essential physics for a straight polarity, diffusion dominated free burning arc in argon, with major simplifications of collisionless sheaths and simple energy balances at the electrodes.

A New Approach to Standardize Multicenter Studies: Mobile Lab Technology for the German Environmental Specimen Bank  

PubMed Central

Technical progress has simplified tasks in lab diagnosis and improved quality of test results. Errors occurring during the pre-analytical phase have more negative impact on the quality of test results than errors encountered during the total analytical process. Different infrastructures of sampling sites can highly influence the quality of samples and therewith of analytical results. Annually the German Environmental Specimen Bank (ESB) collects, characterizes, and stores blood, plasma, and urine samples of 120–150 volunteers each on four different sampling sites in Germany. Overarching goal is to investigate the exposure to environmental pollutants of non-occupational exposed young adults combining human biomonitoring with questionnaire data. We investigated the requirements of the study and the possibility to realize a highly standardized sampling procedure on a mobile platform in order to increase the required quality of the pre-analytical phase. The results lead to the development of a mobile epidemiologic laboratory (epiLab) in the project “Labor der Zukunft” (future’s lab technology). This laboratory includes a 14.7 m2 reception area to record medical history and exposure-relevant behavior, a 21.1 m2 examination room to record dental fillings and for blood withdrawal, a 15.5 m2 biological safety level 2 laboratory to process and analyze samples on site including a 2.8 m2 personnel lock and a 3.6 m2 cryofacility to immediately freeze samples. Frozen samples can be transferred to their final destination within the vehicle without breaking the cold chain. To our knowledge, we herewith describe for the first time the implementation of a biological safety laboratory (BSL) 2 lab and an epidemiologic unit on a single mobile platform. Since 2013 we have been collecting up to 15.000 individual human samples annually under highly standardized conditions using the mobile laboratory. Characterized and free of alterations they are kept ready for retrospective analyses in their final archive, the German ESB. PMID:25141120

The Work Smart Standards process at Jefferson Lab  

SciTech Connect

The Thomas Jefferson National Accelerator Facility (Jefferson Lab) has developed a set of Work Smart Standards for the Lab. The effort incorporated the Lab`s performance-based contract into the Necessary and Sufficient (N and S) Standards identification process of the DOE. A rigorous protocol identified hazards in the workplace and standards that provide adequate protection of workers, public, and the environment at reasonable cost. The intensive process was a joint effort between the Lab and DOE and it required trained teams of knowledgeable experts in three fields: (1) actual required work conditions at Jefferson Lab; (2) laws, regulations, DOE directives and performance-based contracts; and (3) Environmental Health and Safety (EH and S), Rad Con, and QA. The criteria for selection of the teams, the database designed and used for the process, and lessons learned are discussed.

The Madison plasma dynamo experiment: A facility for studying laboratory plasma astrophysics  

NASA Astrophysics Data System (ADS)

The Madison plasma dynamo experiment (MPDX) is a novel, versatile, basic plasma research device designed to investigate flow driven magnetohydrodynamic instabilities and other high-? phenomena with astrophysically relevant parameters. A 3 m diameter vacuum vessel is lined with 36 rings of alternately oriented 4000 G samarium cobalt magnets, which create an axisymmetric multicusp that contains ˜14 m3 of nearly magnetic field free plasma that is well confined and highly ionized (>50%). At present, 8 lanthanum hexaboride (LaB6) cathodes and 10 molybdenum anodes are inserted into the vessel and biased up to 500 V, drawing 40 A each cathode, ionizing a low pressure Ar or He fill gas and heating it. Up to 100 kW of electron cyclotron heating power is planned for additional electron heating. The LaB6 cathodes are positioned in the magnetized edge to drive toroidal rotation through J × B torques that propagate into the unmagnetized core plasma. Dynamo studies on MPDX require a high magnetic Reynolds number Rm > 1000, and an adjustable fluid Reynolds number 10 < Re < 1000, in the regime where the kinetic energy of the flow exceeds the magnetic energy (MA2=(v/vA)2>1). Initial results from MPDX are presented along with a 0-dimensional power and particle balance model to predict the viscosity and resistivity to achieve dynamo action.

Plasma Effects  

NASA Technical Reports Server (NTRS)

Radio communication with space probes requires sending signals through the Earth's ionosphere and usually the solar wind. During planetary flybys, the signal may also pass through the ionosphere of another planet. These ionized media can perturb the radio signal in a variety of ways. Examples of these perturbations are variations in the electrical length between the spacecraft and the ground station, Faraday rotation of linearly polarized signals, amplitude and phase scintillations, and spectral and angular broadening. These plasma effects can have undesirable influences on telemetry performance and thus need to be understood from a communications engineering viewpoint. The plasma effects are, however, useful from a scientific viewpoint, since the effects on the communications link can often be inverted to estimate the physical conditions in the plasma.

Stream piracy in the Black Hills: A geomorphology lab exercise  

USGS Publications Warehouse

The Black Hills of South Dakota exhibits many fine examples of stream piracy that are very suitable for teaching geomorphology lab exercises. This lab goes beyond standard topographic map interpretation by using geologic maps, well logs, gravel provenance and other types of data to teach students about stream piracy. Using a step-by-step method in which the lab exercises ramp up in difficulty, students hone their skills in deductive reasoning and data assimilation. The first exercises deal with the identification of stream piracy at a variety of spatial scales and the lab culminates with an exercise on landscape evolution and drainage rearrangement.

The History of Science and Technology at Bell Labs  

NASA Astrophysics Data System (ADS)

Over the last 80 years, Bell Labs has been one of the most scientifically and technologically productive research labs in the world. Inventions such as the transistor, laser, cell phone, solar cell, negative feedback amplifier, communications satellite and many others were made there. Scientific breakthroughs such as discovery of the Big Bang, the wave nature of the electron, electron localization and the fractional quantum hall effect were also made there making Bell Labs almost unique in terms of large impacts in both science and technology. In my talk, I will discuss the history of the lab, talk about the present and give some suggestions for how I see it evolving into the future.

The EG4 Experiment at Jefferson Lab  

SciTech Connect

The main physics goal of the CLAS EG4 experiment at Jefferson Lab is to measure the generalized GDH sum for the proton and the neutron at very low Q2 down to Q2 = 0.015 (GeV/c)2 (inclusive channels). The same data can be used to extract asymmetries of pion electroproduction in the resonance region (exclusive channels). An overview of the experiment is presented here, as well as the analysis status of both inclusive and exclusive analyses. Some preliminary results on the single-target and the beam-target asymmetries of charged pion electroproductions are presented.

Trapping Lab - Linking Equations and Graphs  

NSDL National Science Digital Library

This activity reinforcse the relationship between the solution to a system of equations and the intersection of their corresponding graph. Generally, students begin to solve systems by using graphing and then algebra. Once a student learns to solve the system by algebra, they often forget the connection to the graph. Hence in this lab, they will use algebra first and then graph their answers. The situation is one where the student is asked to determine where an animal trail intersects with an access road. Given linear equations which represent the placement of the access roads, assign each person/group one or more equations representing an 'animal trail'.

Strangeness Physics with CLAS at Jefferson Lab  

SciTech Connect

We review recent developments in strangeness photo- and electro- production off the proton and neutron, as investigated using CLAS in Hall B at Jefferson Lab. By measuring sufficient spin observables one can decompose the reaction mechanism into elementary amplitudes. We discuss progress toward this end in recent data from CLAS, including cross sections and spin observables. We next discuss new results on the mass distribution of the Lambda(1405), which shows signs of being a composite meson-baryon object of mixed isospin. The work on other hyperons such as the Xi resonances will be mentioned, and future prospects for the CLAS program outlined.

FUTURE SCIENTIFIC OPPORTUNITIES AT JEFFERSON LAB  

SciTech Connect

Nuclear physics requires at least one major facility world-wide which is capable of fully exploiting the properties of the electro-weak force to investigate precisely the structure of strongly interacting systems. At its current maximum energy of 6 GeV Jefferson Lab has provided a wealth of important information on the structure of nucleons and nuclei. However, the plans to double the energy over the next seven years promise to open new frontiers in nuclear and particle physics. We briefly describe the plans for the 12 GeV Upgrade and the associated physics opportunities.

The BEAR program NRL plasma physics instrumentation measurements  

SciTech Connect

The BEAR program was a joint effort to launch, and demonstrate the feasibility of operating, a 1 MeV 10 ma Neutral Particle Beam (NPB) accelerator from a space platform. The accelerator design and manufacture were the responsibility of Los Alamos National Lab (LANL); diagnostics associated with accelerator operation and beam-plasma effects were also to be undertaken by LANL and NRL. Payload Integration and Telemetry was provided by the Air Force Geophysical Lab (AFGL) and Northeastern University (NEU). Beam effects on the local plasma in addition to accelerator produced vehicle effects (e.g., charging) were the responsibility of NRL as outlined herein. The BEAR rocket was launched successfully during the early morning hours of July 13 from White Sands Missile Range, White Sands, N.M. The NRL contribution to this effort included three instrument packages designed to diagnose beam-plasma and vehicle-plasma interactions. The instruments included: (1) Langmuir probe (LP) design consisting of 4 separate sensors; (2) High voltage (HIV) Langmuir Probe designed to monitor vehicle charging through current polarity changes; and (3) Plasma Wave Receive (PWR) designed to characterize the plasma wave emissions covering a broad frequency range from near DC to 50 MHz.

Burning plasmas  

SciTech Connect

The fraction of fusion-reaction energy that is released in energetic charged ions, such as the alpha particles of the D-T reaction, can be thermalized within the reacting plasma and used to maintain its temperature. This mechanism facilitates the achievement of very high energy-multiplication factors Q, but also raises a number of new issues of confinement physics. To ensure satisfactory reaction operation, three areas of energetic-ion interaction need to be addressed: single-ion transport in imperfectly symmetric magnetic fields or turbulent background plasmas; energetic-ion-driven (or stabilized) collective phenomena; and fusion-heat-driven collective phenomena. The first of these topics is already being explored in a number of tokamak experiments, and the second will begin to be addressed in the D-T-burning phase of TFTR and JET. Exploration of the third topic calls for high-Q operation, which is a goal of proposed next-generation plasma-burning projects. Planning for future experiments must take into consideration the full range of plasma-physics and engineering R D areas that need to be addressed on the way to a fusion power demonstration.

Computer-based Astronomy Labs for Non-science Majors  

NASA Astrophysics Data System (ADS)

We describe and demonstrate two laboratory exercises, Kepler's Third Law and Stellar Structure, which are being developed for use in an astronomy laboratory class aimed at non-science majors. The labs run with Microsoft's Excel 98 (Macintosh) or Excel 97 (Windows). They can be run in a classroom setting or in an independent learning environment. The intent of the labs is twofold; first and foremost, students learn the subject matter through a series of informational frames. Next, students enhance their understanding by applying their knowledge in lab procedures, while also gaining familiarity with the use and power of a widely-used software package and scientific tool. No mathematical knowledge beyond basic algebra is required to complete the labs or to understand the computations in the spreadsheets, although the students are exposed to the concepts of numerical integration. The labs are contained in Excel workbook files. In the files are multiple spreadsheets, which contain either a frame with information on how to run the lab, material on the subject, or one or more procedures. Excel's VBA macro language is used to automate the labs. The macros are accessed through button interfaces positioned on the spreadsheets. This is done intentionally so that students can focus on learning the subject matter and the basic spreadsheet features without having to learn advanced Excel features all at once. Students open the file and progress through the informational frames to the procedures. After each procedure, student comments and data are automatically recorded in a preformatted Lab Report spreadsheet. Once all procedures have been completed, the student is prompted for a filename in which to save their Lab Report. The lab reports can then be printed or emailed to the instructor. The files will have full worksheet and workbook protection, and will have a "redo" feature at the end of the lab for students who want to repeat a procedure.

PC/104 Embedded IOCs at Jefferson Lab  

SciTech Connect

Jefferson Lab has developed embedded IOCs based on PC/104 single board computers (SBC) for low level control systems. The PC/104 IOCs run EPICS on top of the RTEMS operating system. Two types of control system configurations are used in different applications, PC/104 SBC with commercial PC/104 I/O cards and PC/104 SBC with custom designed FPGA-based boards. RTEMS was built with CEXP shell to run on the PC/104 SBC. CEXP shell provides the function of dynamic object loading, which is similar to the widely used VxWorks operating system. Standard software configurations were setup for PC/104 IOC application development to provide a familiar format for new projects as well as ease the conversion of applications from VME based IOCs to PC/104 IOCs. Many new projects at Jefferson Lab are going to employ PC/104 SBCs as IOCs and some applications have already been running them for accelerator operations. The PC/104 - RTEMS IOC provides a free open source Real-Time Operating System (RTOS), low cost/maintenance, easily installed/ configured, flexible, and reliable solution for accelerator control and 12GeV Upgrade projects.

Ejs Intro 1D Motion Lab Model  

NSDL National Science Digital Library

The Introductory Physics 1D Motion Lab asks students to develop a computer model for a ball moving vertically under the influence of gravity. When the file is opened, it is initially programmed with a mass moving at constant velocity. It is assumed that students have first collected data of a basketball or volleyball bouncing under a motion detector. The lab instructions fully explain how to build the computer model using Easy Java Simulations modeling tool. The students will learn how to modify the model to simulate a bouncing ball, define variables, calculate relationships, and change the properties for plotting the graph. The calculus is done for the student. Editor's Note: The Easy Java Simulation tool greatly reduces the amount of programming required to develop computer models. Exercises in student-generated modeling are becoming much more widespread in physics education because of the opportunities for students to test and apply their own prototypes to explain and predict physical phenomena. This resource is distributed as a ready-to-run (compiled) Java archive. In order to modify the simulation (and see how it is designed), users must install the Easy Java Simulations Modeling and Authoring Tool.

Control system reliability at Jefferson Lab  

SciTech Connect

At Thomas Jefferson National Accelerator Facility (Jefferson Lab), the availability of the control system is crucial to the operation of the accelerator for experimental programs. Jefferson Lab's control system, uses 68040 based microprocessors running VxWorks, Unix workstations, and a variety of VME, CAMAC. GPIB, and serial devices. The software consists of control system toolkit software, commercial packages, and over 200 custom and generic applications, some of which are highly complex. The challenge is to keep this highly diverse and still growing system, with over 162,000 control points, operating reliably, while managing changes and upgrades to both the hardware and software. Downtime attributable to the control system includes the time to troubleshoot and repair problems and the time to restore the machine to operation of the scheduled program. This paper describes the availability of the control system during the last year, the heaviest contributors to downtime and the response to problems. Strategies for improving the robustness of the control system am detailed and include changes in hardware, software, procedures and processes. The improvements range from the routine preventive hardware maintenance, to improving their ability to detect, predict and prevent problems. This paper also describes the software tools used to assist in control system troubleshooting, maintenance and failure recovery processes.

New GPIB Control Software at Jefferson Lab  

SciTech Connect

The control of GPIB devices at Jefferson Lab is based on the GPIB device/driver library. The library is a part of the device/driver development framework. It is activated with the use of the device configuration files that define all hardware components used in the control system to communicate with GPIB devices. As soon as the software is activated, it is ready to handle any device connected to these components and only needs to know the set of commands that the device can understand. The old GPIB control software at Jefferson Lab requires the definition of these commands in the form of a device control software module written in C for each device. Though such modules are relatively simple, they have to be created, successfully compiled, and supported for all control computer platforms. In the new version of GPIB control software all device communication commands are defined in device protocol (ASCII text) files. This makes the support of GPIB devices in the control system much easier.
