THE EFFECTIVENESS OF THE NEUTRAL PARTICLE BEAM (NPB) MISSILE DEFENSE SYSTEM DEPENDS ON THE SUCCESSFUL ACCELERATION OF HIGH BRIGHTNESS H ION BEAMS AT HIGH CURRENTS WITH CONTINOUS WAVE (CW) OPERATION. PRESENT BASELINE DESIGNS FOR THESE POWERFUL LINAC SYSTEMS INCLUDE ONE OR MORE STAGES OF BEAM COMBINATION (FUNNELING) INTO LATER STAGES OF THE LINAC TO OVERCOME THE CURRENT LIMITATIONS OF THE INITIAL LI ...

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 ...

ANALYTICON PROPOSES DEVELOPING AN ENHANCED SOFTWARE TECHNIQUE FOR PATTERN RECOGNITION THAT WILL BE A FULLY INTEGRATED PROCEDURE, UNLIKE PRIOR TECHNIQUES. THE OBJECTIVE IS PROVIDING A TOOL FOR TESTING KEY ASSUMPTIONS, INTERNAL COMPATIBILITY, AND PERFORMANCE OF RADIOMETRIC TYPING ALGORITHMS - PER ISSUES OF o RAMIFICATIONS ON SIGNATURE UNCERTAINTY STATISTICS OF SIGNATURE MAPPING TO A BEST DECISION-MA ...

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 ...

ASTROPOWER PROPOSES TO DEVELOP A LIGHTWEIGHT, HIGH PERFORMANCE, ULTRA-THIN ELECTROSTATICALLY BONDED GaAs SOLAR CELL WITH COPLANAR BACK CONTACTS. THE INNOVATIVE DESIGN INCORPORATES LIGHT TRAPPING, ADHESIVELESS COVER SLIDE BONDING, AND ELIMINATES GRID SHADING. THIS NOVEL DEVICE WILL EXHIBIT INCREASED EFFICIENCY AND SPECIFIC POWER DUE TO THE HIGHER OPEN CIRCUIT VOLTAGE AND SHORT CIRCUIT CURRENT OBTAI ...

THE OBJECTIVE OF THIS RESEARCH IS TO SEE IF AN EXTREMELY NARROWBAND SODIUM FARADAY ATOMIC LINE FILTER CAN BE USED TO ALLOW ADAPTIVE SYSTEMS USING A SODIUM LASER GUIDE STAR TO WORK UNDER DAYTIME LIGHT CONDITIONS FOR APPLICATIONS SUCH AS IMAGING SATELLITES. THE POTENTIAL APPLICATIONS OF THE FILTER TECHNOLOGY ARE BASED ON THE EXTREMELY SMALL BACKGROUND LIGHT ACCEPTANCE BANDWIDTH OF THE FILTER (ABOUT ...

THIS PROPOSAL IS FOR THE DESIGN OPTIMIZATION AND TESTING OF A HIGH CURRENT SHEET-LIKE ELECTRON BEAM GENERATOR. SPECIFICALLY IT IS FOR A HIGH CURRENT DENSITY (>20A/CM2) SHEET ELECTRON BEAM SOURCE USING A RUGGED LaB(6) CATHODE. SHEET ELECTRON BEAMS ARE VERY DESIRABLE FOR COUPLING TO THE EVANESCENT WAVES IN SMALL MILLIMETER WAVE SLOW-WAVE CIRCUITS, IN ORDER TO GENERATE LARGER POWERS. LaB(6) IS ONE OF ...

DIAMOND HAS A NEGATIVE EELCTRON AFFINITY ON ITS (111) FACE AND P-TYPE DIAMOND IS CONDUCTIVE. UNFORTUNATELY, DOPING OF DIAMOND TO MAKE IT CONDUCTIVE DECREASES THE CARRIER MOBILITIES WHILE INCREASING THE TRAP DENSITIES. EXPERIMENTS WITH P-TYPE DIAMOND HAVE NOT YET PRODUCED SIGNIFICANT CURRENTS. IN THE PROPOSED STUDY AN ENTIRELY NEW APPROACH IS INVESTIGATED. YTHIN WAFERS OF NATURAL TYPE IIa DIAMOND A ...

THIS PROPOSAL IS FOR THE STUDY AND DEVELOPMENT OF A COMPACT, HIGH POWER TUNABLE MILLIMETER WAVE GENERATOR. SPECIFICALLY IT IS FOR A COMPACT OROTRON TUBE OPERATING IN THE 94 GHz (W-BAND) RANGE WITH POWER OUTPUTS ON THE ORDER ON 10 WATTS. SUCCESSFUL DEVELOPMENT OF THE OROTRON DEVICES DEPENDS CRITICALLY ON TWO KEY TECHNOLOGIES, THE GENERATION AND PROPAGATION OF A HIGH CURRENT DENSITY SHEET-LIKE ELECT ...
