THE OXYGEN MOLECULE HAS A NUMBER OF WEAK ABSORPTION LINES INTHE 7000 A SPECTRAL REGION. BY COOLING, THE R1 LINE OF RUBY(A12O3 : CR+3) CAN BE SHIFTED TO COINCIDE WITH 50% ABSORPTION AT LINE CENTER IN THE SOLAR SPECTRUM. RUBY FLUORESCES WITH HIGH QUANTUM EFFICIENCY, WITH A TIME CONSTANT OF APPROXIMATELY 4 MS AT THE TEMPERATURES OF INTEREST. BY DETECTING THE RERADIATED LIGHT, THE RUBY CRYSTAL IS USED ...

THE PROPOSED RESEARCH WILL INVESTIGATE THE DEPOSITION OF AMORPHOUS CARBON THIN FILMS USING A NOVEL LASER ASSISTED DEPOSITION TECHNIQUE. IN THE PHASE I RESEARCH, AERODGNE RESEARCH, INC. WILL DETERMINE THE ABILITY OF THE DEPOSITION TECHNIQUE TO CONTROL THE CARBON BONDING IN THE THIN FILM. IN THE PHASE II STUDIES THEY WILL INVESTIGATE THE RELATIONSHIP BETWEEN DEPOSITION PARAMETERS AND CARBON BONDING ...

FUTURE THREAT INFRARED MISSILE SEEKERS WILL POSSESS THE CAPABILITY TO EFFECTIVELY DISCRIMINATE AGAINST IR DECOY FLARES. NEW DECOY FUELS MUST BE IDENTIFIED WHICH PROVIDE A GOOD SPECTRAL MATCH BETWEEN DECOYS AND HELICOPTERS, AND WHICH HAVE IMPROVED TOTAL RADIANT INTENSITY AND BURNING CHARACTERISTICS. IN ADDITION, ALTERNATIVE DECOY CONCEPTS TO THE FREE-GRAIN FLARE MUST BE EVALUATED. IN THIS PROPOSAL, ...

THE USEFUL OPERATING LIFE OF MOST MECHANICAL SYSTEMS QUITE OFTEN IS DETERMINED BY THE CONTINUED EFFECTIVENESS OF A VARIETY OF TRIBO-ELEMENTS. THESE TRIBO-ELEMENTS ARE THE DEVICES AND MECHANISMS THAT PROVIDE FOR PROPER LUBRICATION AND FRICTIONAL CONTACT BETWEEN MOVING PARTS. SYSTEMS WHICH CAN MONITOR TRIBO-ELEMENT WEAR CAN PERFORM TWO VERY USEFUL FUNCTIONS: 1) THEY CAN MINIMIZE DOWN TIME BY ENSURIN ...

LEAD IODIDE (PBI2) IS A LITTLE USED COMPOUND SEMICONDUCTOR. THE HIGH ATOMIC NUMBERS OF ITS CONSTITUENT ELEMENTS GIVES ITEXTRAORDINARY PHOTOELECTRIC ABSORPTION EFFICIENCY FOR GAMMA PHOTONS, WHILE ITS 2.5 EV BANDGAP PROMISES PERFORMANCEAT TEMPERATURES UP TO 250 DEGREES C. IT HAS SHOWN SOME PROMISE AS A HIGH EFFICIENCY SOLID-STATE DETECTOR, BUT EARLYDEVICES WERE LIMITED BY MATERIAL IMPURITIES AND IMP ...

ACCURATE MEASUREMENT OF NEUTRONS IS DIFFICULT AND REQUIRES COMPLEX, EXPENSIVE EQUIPMENT. IT IS AN ESPECIALLY SERIOUS PROBLEM FOR DOSIMETRY WHERE SEVERAL TECHMICAL ISSUES MAKE THE ACCURATE DTERMINATION OF RADIATION DOSE EXTREMELY DIF- FICULT. FOR EXAMPLE, NEUTRONS OCCUR OVER A WIDE RANGE OF ENERGIES AND HAVE DIFFERENT PHYSICAL PROPERTIES AS A FUNC- TION OF ENERGY. THE MOST COMMON APPROACH TO MAKING ...

MOST OF THE TECHNICAL LITERATURE IN RADAR IS WRITTEN FOR PROFESSIONALSIN THAT FIELD. THE PROPOSED RADAR EVALUATION HANDBOOK WILL CONTAIN TECHNICAL DATA AND PROCEDURES FOR RADAR EVALUATION, BUT WILL BE ADDRESSED TO THE NEEDS OF GENERALISTS FOR WHOM RADAR IS ONLY ONE OF MANY TECHNICAL DISCIPLINES NEEDED IN THEIR WORK. THE MATERIAL WILL TAKE ADVANTAGE OF THE NEW 2ND EDITION OF RADAR SYSTEM ANALYSIS, ...
