PRESENTLY AVAILABLE MASS SPECTROMETER-BASED VACUUM INSTRUMENTS ARE NOT SUITABLE FOR USE IN ANTICIPATED FUSION FACILITIES, WHERE TRITIUM WILL BE USED. THE ION SOURCE IS THE PRIMARY LIMITATION. THIS R&D PROGRAM WILL LEAD TO DEVELOPMENT OF A MINIATURE ECR (ELECTRON CYCLOTRON RESONANT)MICROWAVE ION SOURCE FOR APPLICATION IN LEAK DETECTORS AND VACUUM INSTRUMENTATION. THE ECR ION SOURCE CAN BE DEVELOPED ...

THE UNIQUE PROPERTIES OF DIAMOND MAKE IT ATTRACTIVE AS A MATERIAL FOR USE IN HIGH FREQUENCY, HIGH POWER, MILLIMETER MICROWAVE TUBES AND TRANSMISSION LINES. RECENT ADVANCES IN GYROTRONS AND FREE ELECTRON LASERS (FELS) AS POWER SOURCES, AND EXCELLENT PHYSICS RESULTS FROM THE T-10 TOKAMAK IN THE U.S.S.R. AND BIG-D AT GA TECHNOLOGIES IN THE U.S., HAVE HAD A MAJOR IMPACT ON THE FUSION PROGRAM. AN EXPER ...

N/A

CURRENTLY SURVIVABILITY ASSESSMENTS DO NOT USE ARTIFICIAL INTELLIGENCETECHNIQUES. THE GOAL OF THIS PHASE I PROPOSAL IS TO BUILD A DEMONSTRATABLE KNOWLEDGE SUPPORT SYSTEM TO ASSIST SURVIVABILITY ANALYSTS AND SYSTEM ARCHITECTS IN MAKING SURVIVABILITY ASSESSMENTS. SPECIFICALLY, WE WILL BUILD A SYSTEM INCORPORATING A SATELLITE/WEAPON DESCRIPTION AND PROBABILISTIC METHODS THAT WILL PROVE THE FEASIBILIT ...

THIS WORK WILL DEVELOP A PROCEDURE FOR THE ACOE TO ANIMATE THE OUTPUT DATA FROM VARIOUS FINITE ELEMENT/DIFFERENCE CODES WITH STATE-OF-THEART COLOR COMPUTER GRAPHIC ANIMATION TECHNIQUES. PART OF THIS EFFORT WILL BE THE CREATION OF A MOTION PICTURE (MOVIE) OF AN ACTUAL DYNAMIC FINITE ELEMENT CALCULATION. THE SOFTWARE AND HARDWARE REQUIREMENTS WILL BE ADDRESSED ALONG WITH THE INVESTIGATION OF THE USE ...

THE PROPOSED PROJECT WILL DEVELOP A VIDEO BASED COMPUTER IMAGE PROCESSING SYSTEM CONSISTING OF A 180 DEGREES LENS AND VIDEO CAMERA WHICH IS LINKED TO A VIDEO RECORDER AND MICRO-COMPUTER. THE VIDEO RECORDER ALLOWS FOR STORAGE OF THE IMAGES WHILE THE MICRO-COMPUTER ALLOWS RAPID REAL-TIME ASSESSMENT OF THE UNDERWATER IMAGE WHICH INCLUDES, BUT IS NOT LIMITED TO: (A) ANALYZING MOVEMENT PATTERNS OF FISH ...

THE MAJOR LIMITING RELIABILITY COMPONENT OF CRYOGENIC SYSTEMS HAS ALWAYS BEEN SEALS. BESIDES CONTRIBUTING TO GAS CONTAMINATION AND DEBRIS PARTICLE ACCUMULATION, SEALS HAVE FAILED PHYSICALLY. AS A RESULT, SEALS HAVE BEEN RESPONSIBLE FOR THE MAJORITY OF CRYOGENIC LIQUEFACTION AND REFRIGERATION SYSTEM FAILURES. A POTENTIALLY VIABLE SOLUTION IS THE DEVELOPMENT OF A MULTISEGMENT CERAMIC RING CRYOGENIC ...

THE OBJECT OF THIS RESEARCH IS TO DEVELOP PERMANENT MAGNETS MOTORS HAVING SIGNIFICANTLY HIGHER TORQUE CAPABILITY THAN THE STATE-OF-THE-ART THROUGH THE USE OF AIR-GAP WINDING ARMATURES AND ADVANCED COOLING TECHNIQUES. ACCORDING TO PRELIMINARY STUDIES, THE AIR-GAP WINDING MOTOR HAS A PERFORMANCE FACTOR MORE THAN TWICE AS HIGH AS CONVENTIONAL PERMANENT MAGNET MOTORS, TWO TO THREE TIMES AS MUCH TORQUE ...
