Teaching Newtonian physics involves the replacement of students' ideas about physical situations with precise concepts appropriate for mathematical applications. This paper focuses on the concepts of "matter" and "mass". We suggest that students, like some pre-Newtonian scientists we examine, use these terms in a ...

This book contains papers on the following topics: an introduction to the physics of particle accelerators; transverse motion of single particles in accelerators; fundamentals-longitudinal motion; rf system considerations for a large hadron collider; beam observation and the nature of instabilities; bunched beam diagnostics; fields, ...

Particle Physics in Plain English!, an outreach project for the Lepton Photon 2003 Conference at Fermi National Accelerator Laboratory, discusses how particle physicists are studying antimatter with the hopes of contributing to the current understanding of the universe on all scales, "from revealing the origin of matter shortly after the Big Bang, to ...

The Stanford Linear Accelerator Center, in collaboration with European and Japanese scientists, provides information about the Next Linear Collider (NLC) project. This site includes Collaboration, Detectors, Components, Test Facilities, Concepts, and NLC Technical. Additional links containing information on high-energy physics are also ...

In this review we discuss very briefly main concepts, available observational data and recent theoretical results related to astrophysical asp ects of particle acceleration at/near the Sun. A set of interesting conceptual and physical associations of SCR generation with the high-energy processes at other stars is highlighted.

Isaac Newton, building on earlier descriptions of motion by Galileo, Kepler, and others, created a unified view of force and motion in which motion everywhere in the universe can be explained by the same few rules. Newton's system was based on the concepts of mass, force, and acceleration; his three laws of motion relating them; and a ...

This report discusses the following topics: ion source for the final focusing scaling experiment; reference ILSE physics design; injector and ion source development; the injector matching section; beam merging in ILSE; short quadrupole magnet design; ILSE concept induction cell studies; fast split-harp emittance measurements using a multichannel waveform ...

Particular emphasis is placed on the technology of plasma discharge ion sources which utilize solid elemental or molecular compounds to produce vapor for the ionization process. A brief discussion is made of the elementary concepts underlying the formation and extraction of ion beams from plasma discharge sources. A limited review of low charge state positive ion sources ...

The national laboratory concept, laboratory objectives, the staff, research facilities. research activities, and administration are discussed in general terms and a financial statement is given. Fairly detailed accounts are given for the research programs in the fields of physics, accelerator development, instrumentation, ...
