Rensselaer Polytechnic Institute has been developing transatmospheric 'Lightcraft' technology aimed at creating an efficient, economically affordable, hypersonic mass transportation system. The system utilizes laser-energized airbreathing engines to accel...
ACCEL is a set of computer programs designed to aid in the construction of electronic printed circuit boards. The ACCEL system performs the following tasks - (1) edits the engineers' data, resolves the schematic into a node component-list, looks up physical and electrical data for the parts used in the circuit, and notes any ...

We describe a neutral beam source capable of producing pulsed V for heating and sustaining fusion plasmas. It consists of a large-area plasma source, mulitple-aperture accel-decel extractor, and closely coupled charge- exchange cell. A larger source, to produce 80 A equivalent deuterium beams at 20 keV, is being constructed. (auth)
Proposed action is to construct at BNL a 5,600-ft(sup 2) support building, install and operate a prototypic 200 MeV accelerator and a prototypic 700 MeV storage ring within, and to construct and operate a 15 kV substation to power the building. The accele...

The ion optical system (IOS) of an injector based on an arc multiply charged ion source working in the magnetic field has been computed. The system consists of a PIG-type source with a radial exit slit, an accel-decel electrode system and an electrostatic compensator (Wien filter) to compensate the deflecting action of the magnetic field. It is shown that the hyperbolic ...

The CPS Accel is a commercial PET camera based on a block detector with 64 LSO scintillator crystals (each 6.75 x 6.75 x 25 mm)read out with 4 photomultiplier tubes. The excellent timing resolution of LSO suggests that this camera might be used for time-of-flight (TOF) PET, thereby reducing the statistical noise significantly. Although the Accel achieves 3 ...
