40417 November 18, 1996 American Research Corporation of Virginia This project addresses the hazardous waste problem at Department of Energy sites by developing a new class of ultrafiltration membranes for use in corrosive aqueous or organic streams. These membranes will utilize mesoporous ceramics, which have narrow pore size distributions and tailorabl ...

41292 November 19, 1996 FM Technologies, Inc. A radically new type of particle accelerator, a multiturn recirculating linac operating with space-charge dominated beam currents, has received considerable attention during the last few years. Even with severe limits on the number of turns, the concept potentially offers major cost reductions for a very high ...

41299 November 19, 1996 FM Technologies, Inc. In the Relativistic Klystron Two-Beam Accelerator, which is currently under development, power from a low-energy, high-current, bunched beam is converted to micro-waves via the klystron mechanism and used to provide power for a high-energy linac, specifically a future Next Linear Collider upgrade to l.0 TeV. ...

41307 November 20, 1996 FM Technologies, Inc. High current electron pulses of short duration could be widely used in injector systems for electron accelerators, which have application in industry, medicine, and research. This project will develop a micro pulse electron injector system which is less complex, cumbersome, and expensive than existing systems ...

40169 W. Peter Trower Applications such as medical tomography, x-ray defectometry, and metallurgical processing require high resolution spectrometric detectors. At present, the desired resolution can only be achieved using germanium crystals cooled to cryogenic temperatures, conditions which severely limit applicability. This project will develop x-ray and gamma-ray detectors that operate at r ...

40735 November 13, 1996 Pacific-Sierra Research Corporation Electrical cables used in nuclear power plants are subjected to radiation and thermal stresses which degrade the condition of the insulation material. In-situ non-destructive testing methods are needed to perform cable condition monitoring and remaining life-assessment. Oxidation Induction Time ...

A MICRO-PULSE ELECTRON GUN THAT APPEARS CAPABLE OF PEAK CURRENTS OF ABOUT 10 KA WITH A MICRO-PULSE LENGTH OF SEVERAL PICOSECONDS (PS) OCCURING AT FREQUENCIES OF UP TO 10 GHZ IS BEING PLANNED. THE MICRO-PULSES OR BUNCHES ARE PRODUCED BY RESONANTLY AMPLIFYING A CURRENT OF SECONDARY ELECTRONS IN A RADIO FREQUENCY (RF) CAVITY. BUNCHING OCCURS RAPIDLY AND IS FOLLOWED BY SATURATION OF THE CURRENT DENSIT ...

THIS PROJECT PLANS TO DEVELOP A NOVEL, NONPERTURBING DIAGNOSTIC TO MEASURE THE POSITION, RADIUS, LENGTH, AND/OR CHARGE DISTRIBUTION OF TIGHTLY-FOCUSED, CHARGED PARTICLE BEAMS. THIS DIAGNOSTIC EMPLOYS A LOW ENERGY ( 50 KEV), LOW CURRENT ( 1MUA) STREAM OF IONS TO PROBE THE CHARGED PARTICLE BEAM. THE PROBE IONS ARE INJECTED ACROSS THE PATH OF THE RELATIVISTIC BEAM AND ARE DEFLECTED BY THE ELECTROMAGN ...

THIS PROJECT WILL RESEARCH AND DEVELOP A FLOOR MONITOR FOR QUICK DETERMINATION OF RADIOACTIVE CONTAMINATION. THE MONITOR WILL UTILIZE A NEW PORTABLE TECHNOLOGY (INCLUDING SUPPORT ELECTRONICS). IT WILL HAVE THE CAPABILITY TO MEASURE BETA CONTAMINATION BELOW 5000 DPM/100 CM SQUARED WHEN AVERAGED OVER ONE SQUARE METER AND COVER AN AREA AS LARGE AS SEVERAL SQUARE FEET PER SECOND. IT WILL ALSO BE CAPAB ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.
