Alameda Applied Sciences Corporation (AASC) proposes a three phase effort with the ultimate goal of producing a marketable diamond switch suitable for several pulsed power and other applications in the defence arena. The presently used spark gaps have several drawbacks including switch jitter, large and variable inductance, lifetime and physical size. A low inductance solid-state switch capable ...

40268 November 6, 1996 Alameda Applied Sciences Corporation Induction linear accelerators that produce energetic heavy ion beams are a prime candidate for power-producing fusion reactors. This project will develop and demonstrate a high vacuum arc ion source that can reliably deliver high current, low emittance beams of heavy (A=100-238) ions with charg ...

This proposal seeks to demonstrate the feasibility of using impulse radar techniques to detect and identify concealed weapons. It relies on the fact that a radar impulse will excite natural electromagnetic resonances which characterize the size, shape and material composition of an object. These resonances are present in the scattered transient return from the object and can be extracted by algo ...

THE DEVELOPMENT OF SUPERCONDUCTING RADIO FREQUENCY (RF) ACCELERATOR STRUCTURES HAS PRIMARILY FOCUSSED ON HIGH ENERGYELECTRON ACCELERATORS AND HEAVY ION BOOSTERS FOR ELECTROSTATIC ACCELERATORS. HOWEVER, SEVERAL GROUPS HAVE SUGGESTED THAT THIS TECHNOLOGY MIGHT BE USED TO ACHIEVE A CONTINUOUSLY OPERATING RADIO FREQUENCY QUADRUPOLE (RFQ) ACCELERATING STRUCTURE. THE NORMALLY CONDUCTING RFQ LINEAR ACCEL ...

PARAMETRIC-X-RADIATION (PXR) IS BEING INVESTIGATED IN PHASE I OF THIS PROJECT AS AN INTENSE, MONOCHROMATIC X-RAY SOURCE. THIS RADIATION IS HIGHLY COLLIMATED, HAS A BANDWIDTH OF 0.1% FULL WIDTH AT HALF MIXIMUM, AND AN INTENSITY EQUAL TO THAT OF SYNCHROTON RADIATION ON A PER ELECTRON BASIS. PXR IS PRODUCED BY A HIGH ENERGY (>1MEV) ELECTRON PASSING THROUGH A CRYSTALLINE STRUCTURE; AS THE ELECTRON PAS ...

40458 Adelphi Technology, Inc. This project will design two inexpensive, compact betatron-based electron sources: one at 5-MeV and one at 35-MeV. The primary design object of these two sources will be low emittance (¿n

AVALANCHE PHOTODIODES THAT HAVE LARGE AREA (CURRENTLY 17 MM ACTIVE-AREA DIAMETER BUT POTENTIALLY UP TO 75 MM), UNIFORM HIGH GAIN, AND LOW NOISE, WHEN COMBINED WITH A HIGH VOLTAGE VACUUM PHOTODIODE "FRONT END," MAKE POSSIBLE A HYBRID PHOTODETECTOR THAT COMBINES THE STRENGTHS OF PHOTOMULTIPLIERS AND SOLID-STATE PHOTODETECTORS. THE HYBRID HAS THE PHOTO RESPONSE OF A CONVENTIONAL PHOTOMULTIPLIER. IT C ...
