THE PLASMA BEATWAVE ACCELERATOR IS ONE OF A NUMBER OF PARTICLE ACCELERATOR CONCEPTS UTILIZING THE HIGH FIELDS INHERENT IN INTENSE LASER BEAMS. IN THIS CASE, EM WAVES INTERACT NONLINEARLY WITH AN UNDERDENSE PLASMA THROUGH OPTICAL MIXING OR RAMAN FORWARD SCATTERING (RFS) TO EXCITE LARGE AMPLITUDE PLASMA WAVES. THE PLASMA SELF-FIELDS PROVIDE THE ACCELERATION. THUS, THE CONCEPT IS A COLLECTIVEEFFECT A ...

IN VIEW OF THCURRENT WORLD SITUATION WITH REGARD TO THE AVAILABILITY AND PRICE INSTABILITY OF FOREIGN OIL, THERE IS AN URGENT NATIONAL NEED TO DEVELOP RENEWABLE DOMESTIC ENERGYSOURCES SUCH AS HYDROCARBON-PRODUCING CROPS (BIOMASS). HOWEVER, EFFICIENT AND COST-EFFECTIVE METHODS FOR THE SIMULTANEOUS EXTRACTION OF BOTH THE POLAR AND NON-POLAR CONSTITUTIENTS OF HYDROCARBON-PRODUCING CROPS NEED TO BE DE ...

LINEAR INDUCTION ACCELERATORS ARE THE MEANS BY WHICH PULSED ELECTROSTATIC ACCELERATOR TECHNOLOGY CAN BE SCALED TO HIGH ENERGIES. WE PROPOSE STUDYING ION FOCUSING OF ELECTRONS IN LINEAR INDUCTION ACCELERATORS WITH GOALS OF REDUCING ACCELERATOR COMPLEXITY, COST AND SIZE, DECREASING BEAM EMITTANCE AND IMPROVING STABILITY TO TRANSVERSE DISRUPTIVE BEAM MODES. IN PHASE I RESEARCH, A SMALL INDUCTION LINA ...

THE FASTBUS (MODULAR, HIGH-SPEED DATA ACQUISITION) SYSTEM SPECIFICATION FOR HIGH-ENERGY PHYSICS AND OTHER DATA SYSTEMSAPPLICATIONS HAS DETAILED A SEGMENT INTERCONNECT CONCEPT THAT ALLOWS A USER TO EXPAND A FASTBUS SYSTEM BEYOND THE 26 SLOT BASIC SEGMENT. THIS PROPOSAL DESCRIBES THE DEVELOPMENT OF A DIFFERENT TECHNIQUE, CALLED THE SEGMENT EXTENSION CONCEPT FOR FASTBUS CRATE COUPLING, THAT WILL ALLO ...

COBALT IS A STRATEGICALLY IMPORTANT ELEMENT, AND MINIMIZING ITS USE IS A PROBLEM OF NATIONAL SIGNIFICANCE. COBALT IS USED IN CEMENTED CARBIDES, PARTICULARLY TUNGSTEN CARBIDE-COBALT, WHICH ARE IN TURN USED FOR METAL CUTTING, MINING TOOLS, WIRE DRAWING DIES AND THE LIKE. IN THIS PROPOSAL, TRA SUGGESTS A NOVEL WAY TO IMPROVE THE PROPERTIES OF WC-CO ALLOYS, AND THUS IMPROVE THE USE LIFE OF SUCH ALLOYS ...

THE COST OF DRILLING A GEOTHERMAL WELL IS SIGNIFICANTLY HIGHER THAN THE COST OF DRILLING AN OIL AND GAS WELL AT COMPARABLE DEPTHS. THE HIGHER COST IS DUE PRINCIPALLY TO TWOFACTORS: THE HARDNESS OF THE ROCK FORMATIONS BEING DRILLED AND THE HIGH TEMPERATURES ENCOUNTERED IN DRILLING. THESE TWO FACTORS REDUCE THE RATES OF PENETRATION, THEREBY IN- CREASING THE DRILLING COST. A KEY LIMITATION TO UNDERST ...
