THE PROPOSAL CONCERNS THE IMPROVEMENT OF A CLASS OF HIGH-ENERGY PERMANENT MAGNETS NOW UNDER DEVELOPMENT; HEAT-BONDED COMPOSITES OF HARD MAGNETIC ALLOY POWDERS IN A DUCTILE METAL MATRIX. THE APPLICABILITY OF SN/PB-SOLDER BONDING TO IRON-NEODYMIUM-BORON ALLOYS WILL BE EXPERIMENTALLY EXPLORED. POWDERS OF DIFFERENT PARTICLE SIZES WILL BE PREPARED FROM PRE-SINTERED FE-ND-B, COMPACTS OF THESE WITH SOLDE ...

IN THE PAST FEW YEARS, A CONSIDERABLE INCREASE IN PERFORMANCE HAS BEEN ACHIEVED FROM HIGH SPEED STEEL AND CARBIDE METAL CUTTING TOOLS BY THE ADDITION OF HARD SURFACE COATINGS SUCH AS TITANIUM NITRIDE, SILICON NITRIDE ,TITANIUM CARBIDE, ALUMINUM OXIDE AND VARIOUS COMBINATIONS OF THE ABOVE. THESE COATINGS ARE DIFFICULT TO APPLY UNIFORM LY, PARTICULARLY IN THE CASE OF COMPLEX GEOMETRIES AND ARE EXPEN ...

A NONDESTRUCTIVE TEST DEVICE WILL BE DEVELOPED TO INSPECT NIOBIUM PLATES AND NIOBIUM WELDS FOR DEFECTS WHICH CAUSE ITS SUPERCONDUCTING PROPERTIES TO BE QUENCHED. HIGH QUALITY NIOBIUM IS REQUIRED FOR ADVANCED MACHINES SUCH AS FUTURE GENERATION RADIO FREQUENCY PARTICLE ACCELERATORS. AT PRESENT, THERE IS NO ESTABLISHED TECHNIQUE FOR LOCATING AND DIFFERENTIATING THE TYPES OF DEFECTS CRITICAL TO SUPERC ...

hybrid electric vehicles. While flywheel energy storage systems present viable alternatives, high power densities can only be achieved by high speed operation. This project will develop a motor alternator for an efficient, low-cost, high speed flywheel system with the overall goal of producing a commercially-viable hybrid electric vehicle for the automotive industry. Phase I will identify and c ...

THE OBJECTIVE OF THE PROPOSED PROJECT IS TO FABRICATE AND MEASURE THE PERFORMANCE OF TWO NOVEL DESIGNS FOR REGENERATIVE HEAT EXCHANGERS APPLICABLE TO VARIOUS TYPES OF CRYOCOOLERS, SUCH AS STIRLING AND GIFFORD MCMAHON REFRIGERATORS. THE REGENERATORS PRESENTLY USED ARE LIMITED TO TWO TYPES, AND BASICALLY TWO MATERIALS, DUE TO FABRICATION CONSTRAINTS. THEY ARE RATHER COSTLY, LABOR INTENSIVE, SUBJECT ...

PLASTIC SCINTILLATING OPTICAL FIBERS (PSF) WILL PLAY A MAJORROLE AS RADIATION DETECTORS IN THE GIANT RESEARCH DEVICES ENVISIONED FOR THE SUPERCONDUCTING SUPER COLLIDER (SSC) AND FOR OTHER SIMILAR DEVICES PLANNED ABROAD. THIS PROJECT IS CONCERNED WITH ESTABLISHING A DOMESTIC COMMERCIAL SOURCE OF THIS NEW GENERATION DETECTION MEDIUM NEEDED FOR THE ADVANCEDPARTICLE PHYSICS RESEARCH TO BE CONDUCTED AT ...

RADIO FREQUENCY VACUUM WINDOWS COOLED WITH LIQUID HELIUM WILL BE DEVELOPED IN THIS PROJECT. SINGLE CRYSTAL SAPPHIRE WILL BE USED FOR THE DIELECTRIC BARRIER MATERIAL. A COMPRESSIVE SEAL TECHNIQUE WILL BE USED TO FORM THE VACUUM JOINT BETWEEN THE SAPPHIRE AND CONDUCTORS THAT MAKE UP THE WINDOW ASSEMBLY. THIS TECHNIQUE HAS BEEN USED SUCCESSFULLY FOR ROOM TEMPERATURE VACUUM SEALS. IN PHASE I THE SEAL ...

THERE IS INCREASING INTEREST WITHIN THE HIGH ENERGY PHYSICS COMMUNITY IN INVESTIGATING ELECTRON INTERACTION PHENOMENA ATENERGIES NEAR 1 TEV. A LINEAR COLLIDER, HAVING A DESIGN BASED ON THE RELATIVISTIC KLYSTRON TWO-BEAM ACCELERATOR (RK/TBA) DESCRIBED BY SESSLER AND YU, OFFERS A PARTICULARLY ATTRACTIVE APPROACH TO ACHIEVING SUCH ENERGIES. IN THIS APPROACH, HIGH ENERGY, LOW CURRENT ELECTRON BEAMS AR ...

THE FASTBUS SYSTEM SPECIFICATION FOR HIGH ENERGY PHYSICS ANDOTHER DATA-SYSTEM APPLICATIONS ANTICIPATES THE USE OF MULTIPLE, HIGH PERFORMANCE PROCESSOR MODULES FOR DATA CONTROL AND EVENT REDUCTION ASSOCIATED WITH EXPERIMENTS IN THE PHYSICAL SCIENCES. EXISTING PROCESSOR DESIGNS WILL BE UNABLE TO COPE WITH THE PROJECTED DATA-REDUCTION AND EVENT-HANDLING REQUIREMENTS OF THE COMPLEX EXPERIMENTS PLANNED ...

ONE OF THE MANY WAYS OF USING COAL AS A FUEL FOR GENERATING ELECTRIC POWER IS TO PULVERIZE IT INTO A VERY FINE SIZE (2-20 MICRONS) AND MIX IT WITH A LIQUID CARRIER SUCH AS WATER. THE RESULTING SLURRY CAN BE TRANSPORTED THROUGH A PIPELINE AND INJECTED DIRECTLY INTO A BOILER FOR COMBUSTION. PULVERIZING COAL INTO A FINE POWDER LEADS TO GREATER ASH REJECTION LEVELS AND THEREFORE TO CLEANER COAL. THIS ...
