THIS PHASE I PROGRAM WILL ENTAIL DESIGN AND DEVELOPMENT OF A COMPACT REHEAT BURNER AND EJECTOR AUGMENTATION SYSTEM. A HEAVY WALL PROTOTYPE WILL BE PROVIDED TO THE GOVERNMENT FOR TEST EVALUATION.

This research will substantially advance the state of the art in single-chip photodetector arrays. Advanced Photonix, Inc. manufactures unique large-area, single-element silicon avalanche photodiodes (currently 16mm active-area diameter,but potentially up to 75mm). The research will demonstrate feasibility (Phase I) and produce a prototype (Phase II) of such a photodetector subdivided into an arra ...

DARPA AND THE U.S. SEMICONDUCTOR COMMUNITY ARE ACTIVELY DEVELOPING LASER-PRODUCED PLASMA (LPP) X-RAY SOURCES AS THE BASIS FOR X-RAY MICROLITHOGRAPHY EXPOSURE SYSTEMS. THESE LPP SOURCES WILL ALLOW THE CONSTRUCTION OF COMPACT EXPOSURE SYSTEMS THAT CAN BE EASILY INTEGRATED INTO EXISTING SEMICONDUCTOR FABRICATION LINES, AT A COSTSUBSTANTIALLY LESS THAN THAT OF COMPARABLE SYNCHROTRON EXPOSURE BEAM-LINE ...

THE SCANNING PHOTOVOLTAGE (SPV) TECHNIQUE IS A NON-DESTRUCTIVE, HIGH RESOLUTION OPTICAL METHOD FOR MAPPING ELECTRICALLY-ACTIVE DEFECTS IN SEMICONDUCTORS. THE POTENTIAL OF THE SPV TECHNIQUE HAS NOT BEEN REALIZED FOR MODERN, ULTRA-THIN FILM MATERIALS, HOWEVER, BECAUSE OF MULTIPLE REFLECTION INTERFERENCE EFFECTS WHICH MASK THE DEFECT-RELATED SIGNALS. MEASUREMENTS ARE FURTHER HAMPERED BY LOW SIGNAL-TO ...

THIS PROPOSAL DESCRIBES AN INNOVATIVE AND PROPRIETARY MULTIPLE DETECTOR FOCAL PLANE ASSEMBLY (FPA) DESIGNED TO BE USED FOR HIGH RESOLUTION 3 DIMENSIONAL IMAGING (STARING) UNDERWATER LASER RADAR. THIS FPA DESIGN HAS THE FOLLOWING CHARACTERISTICS: CAN BE USED TO DETERMINE THE TIME-OF-ARRIVAL OF A LASER PULSE AT EACH DETECTOR ELEMENT IN THE ARRAY INDEPENDENT FROM THE OTHER DETECTOR ELEMENTS IN THE AR ...

Phase I will develop an advanced photocathode for high quantum efficiency, photon-counting sensitivity of 1.06 microsecond, Nd:YAG laser pulses. As far as maximum ladar range is concerned the proposed photocathode is equivalent to an increase of a factor of 15 in laser power. The photocathode is called the High Quantum efficiency Photocathode (HiQ-PC) and is characterized by: (1) High Quantum Effi ...

Phase I will develop a breakthrough in a Infrared (IR) detector, called the Super Sensitive Solid-State Infrared Detector because it: does not require indium bumping readout technology; can detect individual IR photons between 2 and 24 micrometers; is insensitive to gamma rays; has very low dark current; and has a large dynamic range from the lowest possible flux to 10E14 photons/cm2-sec. The Supe ...

THE FOLLOWING PROPOSAL COMBINES TWO TECHNICAL INNOVATIONS, A GENERALIZED SINGULAR LINEAR QUADRATIC (GSLQ) ADAPTIVE CONTROL SCHEME AND A CEREBELLAR MODEL ARITHMETIC COMPUTER (CMAC), FOR THE PURPOSE OF ACHIEVING A HIGH PRECISION, ROBUST, ADAPTIVE WEAPON CONTROL SYSTEM DESIGN. THE BENEFITS OF THE RESULTING WEAPON CONTROL SYSTEM ARE SEVERAL: (1) A MULTI-INPUT AND MULTI-OUTPUT (MIMO), ADAPTIVE CONTROL ...

WE PROPOSE AN EFFICIENT AND COST-EFFECTIVE QUERY PROCESSING COMPONENT FOR AN INFORMATION RETRIEVAL SYSTEM BASED ON THE USE OF NETWORKED MICROCOMPUTERS AS A LOOSELY-COUPLED NETWORK DATABASE. THE QUERY PROCESSSING SYSTEM WILL WORK ON BOTH LOCAL AND WIDE AREA NETWORKS AND CAN BE USED WITH ANY METHOD OF INFORMATION RETRIEVAL. WE PROPOSE TO: 1. MODEL THE EXPECTED PERFORMANCE OF THIS SYSTEM SO THAT IT M ...

AstroPower is developing a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51In.49P lattice matched to GaAs for use as the top cell in a three-junction, two-terminal tandem stack. This tunable bandgap material system is capable of current matching, at 2.03eV, in a two-junction monolithic tandem solar cell two terminal design of (AlxGa1-x)0.51In0.49P/GaAs yielding a best case pred ...
