Manning Applied Technology proposes development of the MP-100 handheld FT-infrared photoacoustic chemical agent detector, following a highly successful Phase I effort. Chemical attacks and accidents can be mitigated partially by cost-effective sensors. High priority programs will benefit from a sensor compliant to Joint Warning & Reporting Network (JWARN) standards. The device is ideally suited to ...

¿Clean energy¿ is attracting more and more interest, which in turn exerts cost pressure on photovoltaic (PV) manufacturers for more efficient solar panel production. This project will develop a cost-effective technology to produce PV-grade silicon wafers. In Phase I, a non-oxide-based reuseable crucible was developed for the production of high purity, low oxygen content crystalline silicon ing ...

CRYOGENIC HELIUM REFRIGERATORS AND LIQUIFIERS CONVENTIONALLYEMPLOY OIL LUBRICATED POSITIVE DISPLACEMENT COMPRESSORS AT THE WARM END AND FREQUENTLY USE PISTON TYPE EXPANSION ENGINES AT THE COLD END. THESE SYSTEMS REQUIRE EXTENSIVE AND VIGILANT MAINTENANCE TO CONTROL CONTAMINATION FROM LUBRICATING OIL AND ITS VOLATILE COMPONENTS MIGRATING TO THE COLD END. HENCE THE NEED FOR LOW MAINTENANCE COMPRESSO ...

IN MOST CRYOGENIC SYSTEMS, THE PIPING JOINTS IN COLD REGIONSOF THE SYSTEM ARE MADE BY WELDING OR SOLDERING. THIS IS ESSENTIAL BECAUSE EXISTING DESIGNS OF CRYOGENIC PIPE SEALS CANNOT BE RELIED ON NOT TO LEAK. ANY SUCH LEAKS INTO THE COLD BOX REDUCE THE EFFECTIVENESS OF THE INSULATION, THEREBY REDUCING THE EFFICIENCY OF THE REFRIGERATOR. WELDEDJOINTS MAKE REPLACEMENT OF COMPONENTS DIFFICULT AND HAVE ...
