THE OBJECTIVE OF THIS PROPOSAL IS TO DEVELOP A MORE EFFICIENT, HIGH POWER MILLIMETER WAVE SOURCE BY MODIFYING THE ORIGINAL ORBITRON MASER. THE ORIGINAL ORBITRON IS DRIVEN BY A SINGLE POWER SUPPLY (I.E.A SMALL CAPACITOR) WHICH GENERATES AN AXISYMMETRIC LOGARITHMIC POTENTIAL-WELL AS RADIALLY DIRECTING (AT FIRST) ELECTRON BEAMS IN THE TUBE OF COAXIAL GEOMETRY. HOWEVER, THE POSITIVE POTENTIAL (V(O)) I ...

CONVENTIONAL FUSION PROCESSES ARE NOT EXPECTED TO ACHIEVE BREAK-EVEN WITHIN THE NEXT DECADE. COLD FUSION IS AN EXCITING OPTION, SINCE IT OFFERS AN INEXPENSIVE ALTERNATIVE AND SOME CLAIM BREAK-EVEN HAS ALREADY BEEN ACHIEVED. HOWEVER, TO DAT, NO IN-DEPTH THEORETICAL STUDY OF COLD FUSION HAS BEEN CONDUCTED. LOW NEUTRON FLUX AND THE USE OF LITHIUM HYDROXIDE AS AN ELECTROLYTE IN THE FUSION CELLS USED B ...

THERE IS A NEED FOR UNIQUE JOING/BONDING PROCESSES THAT CAN DIRECTLY JOIN CERAMIC IR AND RF DOME COMPONENTS TO CYLINDRICAL METAL SURFACES. EXPOSURE TO THE HIGH TEMPERATURES ASSOCIATED WITH CONVENTIONAL BRAZING PROCESSES CAN DEGRADE THE OPTICAL PROPERTIES OF MATERIALS AND PROMOTE CHEMICAL REACTION BETWEEN THE BRAZE MATERIAL AND THE CERAMIC THROUGHOUT THE ENTIRE HEAT AFFECTED ZONE (HAZ). THEREFORE, ...

THE RECENT DISCOVERY OF NEW HIGH TEMPERATURE SUPERCONDUCTOR SYSTEMS HAS CREATED A NEED TO DEVELOP COMPATIBLE MEASUREMENTTECHNIQUES TO CHARACTERIZE THE ELECTRICAL, STRUCTURAL, ACOUSTIC AND OPTICAL PROPERTIES OF THESE MATERIALS. ALTHOUGH MANY STANDARD METHODS OF MEASURING CONVENTIONAL SUPERCONDUCTING MATERIALS CAN BE ADAPTED TO NEW HIGH TC SUPERCONDUCTOR SYSTEMS, EFFECTIVE MEASUREMENT OF CRITICAL PR ...

RECENT DEVELOPMENTS IN VERY HIGH SPEED INTEGRATED CIRCUITS (VHSIC) HAVE LED TO THE NEED FOR HIGH EFFICIENCY AND POWER DENITY RESONANT MODE AND SWITCHED MODE POWER SUPPLIES, OPERATING AT FREQUENCIES IN EXCESS O 1 MEGAHERTZ (MHZ). THE SPECIFICATIONS FOR THESE POWER SUPPLIES ARE STINGENT DUE TO REQUIREMENTS NECESSARY FOR RELIABLE POWER SOURCES. THESE REQUIREMENTS ARE DRIVING OPERATING FREQUENCIES TO ...

ADVANCES IN REAL-TIME MEASUREMENT TECHNIQUES FOR CHARACTERIZING STRUCTURAL AND PROPULSION SYSTEM PROPERTIES REQUIRE ACCURATE MEASUREMENT OF DYNAMIC PROPERTIES IMPORTANTTO THE DESIGN OF ADVANCED AERONAUTICAL AND AEROSPACE VECHICLES. THE SPECIFIC INNOVATION ADDRESSED BY THIS PROPOSAL IS THE EMPLOYMENT OF A NON-INTRUSIVE, RUGGED OPTICAL IMAGING METHOD COMPATIBLE WITH ROUGH AND POORLY REFLECTING ADVAN ...
