AVAILIBILITY OF SILICON RADIATION DETECTORS WITH LARGE SENSITIVE DEPTHS HAS BEEN SERIOUSLY RESTRICTED BY LACK OF A GOOD SUPPLY OF VERY HIGH RESISTIVITY, HIGH QUALITY, SINGLE CRYSTALS OF SILICON. THIS PROGRAM IS DIRECTED AT A COST-EFFECTIVE AND RELIABLE METHOD FOR MAKING SILICON FOR DETECTORS WITH SENSITIVE DEPTHS BEYOND SEVERAL MILLIMETERS. THE METHOD IS BASED ON AN INNOVATIVE CONCEPT FOR CIRCUMVE ...

THE DISCOVERY OF THE YBA(2)CU(3)O(7)-(X)(123) SUPERCONDUCTORS WITH A CRITICAL TEMPERATURE (T(C)) WELL ABOVE LIQUID NITROGEN TEMPERATURES BROUGHT THE LEVEL OF INTEREST AND EXCITEMENT IN SUPERCONDUCTIVITY TO UNPRECEDENTED HEIGHTS. UNFORTUNATELY, THE TRANSPORT CURRENT DENSITY (J(C)) OF THIS MATERIAL, ESPECIALLY IN BULK-PROCESSED POLYCRYSTALLINE POWDERS, IS NOT HIGH ENOUGH. THIS IS BELIEVED TO BE DUE ...

THIS RESEARCH ADDRESSES THE NEED FOR OXYGEN SENSORS TO PROVIDE HIGHLY LOCALIZED, RAPID SENSING (ON THE MICRON SCALE) WHILE OPERATING IN A CORROSIVE ATMOSPHERE AT ELEVATED TEMPERATURE AND/OR PRESSURE. THE MATERIALS USED WILL BE IN THE FORM OF COMPLEX EUTECTIC THIN-FILMS. AN INTENSE LASER BEAM WILL BE USED TO SOLIDIFY DIRECTIONALLY EUTECTIC FILMS OF ZRO(2) WITH MO, ZRC, AND ZRN. TWO OF THESE THREE S ...

THIS PROJECT WILL EXAMINE THE FEASIBILITY OF DEPRESSED COLLECTORS FOR GYROTRONS FOR ACCELERATOR DRIVERS. GYROTRONS ARE POTENTIAL RF DRIVERS FOR ACCELERATORS INVOLVING VERY HIGH AVERAGE POWERS, E.G., 200 MW FOR THE 300-500 GEV ELECTRON-POSITRON COLLIDER. THE EFFICIENCY OF THE GYROTRONS WILL THEN HAVE A LARGE ECONOMIC IMPACT. DEPRESSED COLLECTORS ARE COMMONLY USED IN CONVENTIONAL TUBESFOR EFFICIENCY ...

THIS PROJECT IS A TECHNICAL STUDY OF A DISTRIBUTED ROBOT CONTROL SYSTEM. THE SENSORY PROCESSING PORTION OF THECONTROLLER WILL BE STUDIED IN DETAIL WITH ATTENTION BEING FOCUSED ON INDUSTRIAL AND MOBILE TELEROBOTIC APPLICATIONS IN THE NUCLEAR POWER INDUSTRY. A THREE DIMINSIONAL MACHINE VISION SYSTEM AND PARALLEL COMPUTATION HARDWARE WILL BE USED TO PROCESS DENSE PIXEL LEVEL INFORMATION FROM VIDEO CA ...

SOLVENT EVAPORATION IN INDUSTRIAL DRYING CHAMBERS IS AN ENERGY INTENSIVE PROCESS THAT CURRENTLY UTILIZES ENERGY IN A VERY INEFFICIENT MANNER. THIS IS DUE TO THE FACT THAT THESE DRYERS TYPICALLY OPERATE AT SOLVENT VAPOR CONCENTRATIONS ON THE ORDER OF 7% OF THE LOWER EXPLOSIVE LIMIT (LEL) IN ORDER TO ENSURE SAFE OPERATION. HOWEVER, IF A CONTINUOUS VAPOR CONCENTRATION MONITOR AND SAFETY INTERLOCKS WE ...
