WIRE CHAMBERS ARE A CLASS OF PARTICLE TRACK DETECTORS THAT HAVE FOUND WIDE APPLICATIONS IN HIGH ENERGY PARTICLE PHYSICS EXPERIMENTS. LARGE WIRE CHAMBER DETECTORS HAVE BECOME RATHER COMPLEX, REQUIRING MANY FAST ELECTRONIC CIRCUITS. THIS INVESTIGATION OFFERS THE POTENTIAL OF SIMPLIFICATION AND COST REDUCTION FOR LARGE WIRE CHAMBER DETECTORS. THE PHASE I EFFORT IS INVESTIGATING THE FEASIBILITY OF USI ...

PHASE I ADDRESSES A NEW APPROACH FOR THE DESIGN OF HIGH POWER NUCLEAR TARGETS USED FOR PRODUCTION OF RADIOISOTOPES BY HIGH ENERGY CHARGED PARTICLE BEAMS, NOTABLY HIGH ENERGY PROTONS. SUCH TARGETS WILL YIELD LARGER QUANTITIES OF RADIOACTIVE SPECIES THAN PRESENTLY AVAILABLE, EITHER FOR BASIC RESEARCH (E.G., STUDIES USING RADIOACTIVE BEAMS) OR FOR APPLIED PURPOSES (E.G., PRODUCTION OF MEDICAL RADIOI ...

A Shortfall in marine fisheries production is driving the development of aquaculture technologies on many fronts. Recirculating systems are regarded as critical components of many development schemes. However, interest and use of recirculating systems for production of marine organisms have lagged behind freshwater applications. A floating bead filter which is corrosion resistant (no metal parts), ...

ADVANCES IN TECHNOLOGY INDICATE THAT IT MAY BE POSSIBLE TO DEVISE A RELATIVELY SIMPLE HIGH ACCELERATION GRADIENT ELECTRON BEAM ACCELERATOR BY COMBINING A LOW-EMITTANCE, LASER-DRIVEN PHOTOCATHODE WITH A RADIAL LINE LINAC WITH ULTRA-SHORT PULSES CONTROLLED BY A PICOSECOND PULSE LASER (SUGGESTED BY W. WILLIS). GRADIENTS OF 1 GEV/METER MAY BE POSSIBLE. THE FEASIBILITY OF THIS CONCEPT WILL BE ASSESSED ...

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 ...

We will develop technology, termed a Ruggedized Wind Measurement System (RWMS), to measure directly extreme winds with high space and time resolution, focusing on the winds that occur beneath hurricanes at land fall. This development effort will include design, fabrication of two prototype RWMS units, and a series of proof-of-concept demonstrations in strong mountain-induced downslope and severe t ...

RESEARCH IN THIS PROJECT IS BEING CONDUCTED TO DEVELOP A COMPACT, RUGGED, ON-LINE, MULTIPLE INPUT, FIBER OPTIC-BASED RAMAN PROCESS MONITORING AND CONTROL SENSOR CAPABLE OF OPERATING IN HARSH INDUSTRIAL ENVIRONMENTS. CHARGE-COUPLED DEVICE ARRAY DETECTOR-BASED RAMAN SPECTROSCOPY, EMPLOYING LASER DIODES AND OPTICAL FIBER PROBES, CAPABLE OF SENSITIVITIES COMPARABLE TO OR BETTER THAN THE FOURIER TRANSF ...
