A SOLID STATE SWITCH FOR OPERATION AT CRYOGENIC TEMPERATURE IS BEING DEVELOPED THAT WILL PROVIDE MULTI-MEGAWATT POWER CONDITIONING IN THE RAPIDLY EXPANDING FIELD OF LOW TEMPERATURE ELECTRONICS. SINCE EXISTING CONTROLLED SWITCHES ARE NOT DIRECTLY SUITABLE FOR CRYOGENIC OPERATION, ONLY A FUNDAMENTAL APPROACH CAN DEVELOP STRUCTURES CAPABLE OF LOW LOSS AND RELIABLE OPERATION IN THE TEMPERATURE RANGE B ...

COMPOSITE MATERIALS USED IN SPACE STRUCTURES REQUIRE PROTECTION FROM CORROSION, OXIDATION AND WEAR. CURRRENT TECHNIQUES SUCH AS VAPOR DEPOSITION AND PLATING SUFFER MANY DRAWBACKS. PHASE I RESEARCH WILL DEVELOP A SIMPLE, RELIABLE LASER COATING TECHNIQUE TO APPLY AMORPHOUS METALLIC COATINGS ON METAL MATRIX COMPOSITES AND THEREBY PROVIDE TRIBOLOGICALLY AND ENVIRONMENTALLY EFFECTIVE SURFACES. RAPID SO ...

THE MOVING MECHANICAL ASSEMBLIES IN SPACE STRUCTURES NEED SOLID LUBRICANTS FOR EXTREME ENVIRONMENTS. FLUORINATED DIAMOND OR DIAMOND-LIKE CARBON OFFERS PROMISE BECAUSE ITS DIAMOND-LIKE CARBON PROVIDES LOW FRICTION AND FLUORINE ATOMS CAN PASSIVATE THE SURFACE LAYER. PHASE I WORK WILL DEVELOP AN INNOVATIVE PHOTOTHERMAL CHEMICAL VAPOR DEPOSITION TECHNIQUE TO SYNTHESIZE FLUORINATED DIAMOND FILMS ON SPA ...

CUBIC BORON NITRIDE (CBN) HAS POTENTIAL AS A HIGH QUALITY, HIGH TEMPERATURE SEMICONDUCTOR LIKE DIAMOND AND SIC. SYNTHESIS OF CBN BY CHEMICAL VAPOR DEPOSITION AND PHYSICAL VAPOR DEPOSITION TECHNIQUES YIELDED FILMS OF LOW QUALITY THAT CAN NOT BE USED FOR ELECTRONIC DEVICES. PHASE I WILL DEVELOP AN INNOVATIVE LASER TECHNIQUE INVOLVING ND:YAG AND EXCIMER LASERS TO GROW HETEROEPITAXIAL FILMS OF CBN ON ...

INFRARED SYSTEMS ARE NEEDED FOR A VARIETY OF DEFENSE RELATED APPLICATIONS, SUCH AS: SURVEILLANCE, TARGET DETECTION, ACQUISITION AND TRACKING, MISSILE GUIDANCE, ETC. FOR MANY APPLICATIONS SUCH AS THOSE INVOLVING COLD-DIM TARGETS, THESE SYSTEMS NEED TO OPERATE IN THE VERY LONG WAVELENGTH REGION OF THE INFRARED SPECTRUM, E.G. 15-35 MICRONS CUTOFF. IN THIS WAVELENGTH REGION, THE AVAILABILITY OF SUITAB ...
