184 Diamond Fast Opening Breaking Switches--Alameda Applied Sciences Corporation, 2235 Polvorosa Avenue, Suite 230, San Leandro, CA 94577-2249; (510) 483-4156 Dr. Rahul R. Prasad, Principal Investigator Dr. Mahadevan Krishnan, Business Official DOE Grant No. DE-FG03-97ER82320 Amount: $74,989 Alameda Applied Sciences Corporation will develop a fast-opening breaking switch to improve the heati ...

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 ...

75488-Pulsed ion sources are used in a variety of applications from heavy ion fusion to space propulsion. In order to optimize the ion beams that are produced, it is necessary to have a very high degree of reproducibility from pulse to pulse. Liquid metal ion sources have been shown to provide beams with extremely low noise and no significant charge state variation; however, the useful emitter c ...

75521-Radio frequency (rf) cavities are a key component in particle accelerators for fundamental high-energy physics research and medical applications. To enhance their capabilities, niobium coated, superconducting copper cavities have shown promise for supporting higher electric field gradients, compared to non-superconducting designs. However, a satisfactory coating method has not been develop ...

CURRENT ACTIVITY WITHIN THE NRC AND THE NUCLEAR INDUSTRY SEEKS TO EXPLOIT THE BENEFITS OF PRA IN RISK-BASED APPROACHES TO RELIEVE REGULATORY BURDEN ON THE ECONOMICALLY THREATENED NUCLEAR POWER PLANTS. THE ACCIDENT PREVENTION GROUP HAS BEEN DEVELOPING THE CONCEPT OF AN INTEGRATED RISK MANAGEMENT PROGRAM (IRMP) TOWARD SUCH GOALS. A KEY ELEMENT OF AN IRMP IS AN "OPERATIONAL RISK MODEL" OF THE NPP THA ...

WE PLAN TO INVESTIGATE THE USE OF RESONANCE TRANSITION RADIATION TO IDENTIFY ULTRA-RELATIVISTIC CHARGED PARTICLES. WE WILL LOOK INTO METHODS FOR SINGLE AND MULTIPLE PARTICLE IDENTIFICATION. BY SELECTING FOIL THICKNESS AND SPACING, IT IS POSSIBLE TO DESIGN RADIATORS WHOSE ANGLE OF EMISSION INCREASES WITH THE ENERGY OF THE INCIDENT CHARGED PARTICLE. BY NOTING THE STRONG ANALOGOUS RELATIONSHIP BETWEE ...

THE OBJECTIVE OF THIS PROJECT IS TO EMPLOY THE BETATRON PRINCIPLE TO PRODUCE AN INEXPENSIVE ELECTRON ACCELERATOR CAPABLE OF PRODUCING 20-50 MEV ELECTRONS WITH GOOD BEAM QUALITY AND HIGH-AVERAGE CURRENTS OF UP TO 5-50 MUA. IN CONVENTIONAL BETATRONS WHICH HAVE BEEN IN EXISTENCE FOR OVER 50 YEARS, EDDY-CURRENT LOSSES IN THE IRON LIMIT THE OPERATING FREQUENCY, THUS LIMITING THE MAXIMUM ENERGY AND CUR ...

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

75903-Neutron radiography, which uses nuclear reactors and accelerators as sources of neutrons, has been demonstrated to be an excellent method for imaging high-density, thick objects for the detection of corrosion, voids, and cracks, particular in nuclear power plants. Unfortunately, no high brightness neutron sources exist that are portable, inexpensive and capable of neutron radiography in sho ...
