THIS RESEARCH WILL EXPLORE THE POSSIBILITIES AND RESULT IN THE DESIGN OF AN ACOUSTIC ENERGY GENERATOR FOR GEOPHYSICAL EXPLORATION IN INACCESSIBLE MOUNTAINOUS TERRAIN. THIS EFFORT WILL DETERMINE THE MAGNITUDE OF ACOUSTIC SIGNAL REQUIRED AND WILL DEVELOP A TECHNIQUE FOR COUPLING THE SIGNAL GENERATOR TO THE EARTH. THE COUPLING TECHNIQUE WILL EXAMINE FORCES OTHER THAN GRAVITY TO ENSURE THAT THE SIGNAL ...

78830 The Department of Energy requires improved measurement techniques to quantify trace gas species in the atmosphere, in order to achieve further understanding of the formation of aerosols and their role in climate change. This project will combine a novel, ultra-sensitive, photo-acoustic detection technique with a high power, widely tunable mid-infrared laser source to enable rapid, sub-part- ...

COALESCING THE FRAGMENTED INFORMATION ASSOCIATED WITH EACH EVENT OF A HIGH-ENERGY PHYSICS DETECTOR AND THEN PROCESSING IT AT THE RATES DEMANDED BY ACCELERATOR SYSTEMS ARE AMONG THE LARGEST CHALLENGES IN THE PHYSICS COMMUNITY. NEW DETECTOR SYSTEMS CONTINUE TO INCREASE THE NUMBER OF MEASURED PARAMETERS AND SIMULTANEOUSLY INCREASE THE RESOLUTION OF DETECTOR COMPONENTS SO THAT THE VOLUME OF GENRATED ...

THE MAJOR LIMITING RELIABILITY COMPONENT OF CRYOGENIC SYSTEMS HAS ALWAYS BEEN SEALS. BESIDES CONTRIBUTING TO GAS CONTAMINATION AND DEBRIS PARTICLE ACCUMULATION, SEALS HAVE PHYSICALLY FAILED; AS A RESULT, SEALS HAVE BEEN RESPONSIBLE FOR THE MAJORITY OF FAILURES OCCURRING IN CRYOGENIC LIQUIFICATION AND REFRIGERATION SYSTEMS. A POTENTIALLY VIABLE SOLUTION IS THE DEVELOPMENT OF LONG-LIFE CRYOGENIC SEA ...

ION SOURCES BASED ON VACUUM ARC TECHNOLOGY HAVE SEVERAL IMPORTANT ADVANTAGES. THEY CAN GENERATE A WIDE VARIETY OF METAL IONS, PRODUCE HIGH CURRENT FRACTIONS OF MULTIPLY-CHARGED IONS, AND ARE EASY TO OPERATE. UNFORTUNATELY, EXISTING ARC SOURCES HAVE TECHNOLOGICAL DRAWBACKS. A STABLE DISCHARGE REQUIRES HIGH CURRENT (>200A), LIMITING THE SOURCE PULSE LENGTH AND LIFETIME. IN THIS PHASE I PROJECT, IMPR ...

78807 The remote detection of chemical signatures for nuclear proliferation, requires a pump laser capable of driving a tunable ultraviolet light source. The pump laser must be compact and efficient, and produce a very high quality beam. This project will build a pump laser with a relatively new laser material, Yb:S-FAP, developed by the DOE at Lawrence Livermore National Laboratory. Yb:S-FAP a ...
