WHILE THE THEORETICAL BOUNDS ON THE ENERGY STORED BY AND THE POWER OUTPUT OF ELECTROCHEMICAL POWER SOURCES ARE WELL DEFINED BY THERMODYNAMIC AND PHYSICAL CONSIDERATIONS, THE DEGREE TO WHICH ONE CAN APPROACH THE THEORETICAL BOUNDS IS DETERMINED BY CONTRAINTS IMPOSED BY THE DESIGN OF THE ELECTRODES AND PACKAGING MATERIALS. THIS RESEARCH DEALS WITH AN INNOVATIVE CONCEPT FOR MATERIALS AND PACKAGE DESI ...

THE PROPOSED PROGRAM RELATES TO THE EVALUATION OF A NEW CATHODE CATALYST IN DIS-TYPE LI/SOC12 CELLS. THIS NEW CA CATALYST HAS BEEN SHOWN TO CHANGE THE CATHODE REACTION MECHANISM AND TO INCREASE BOTH CATHODE RATE (FACTOR OF TEN) AND CAPACITY (FACTOR OF AT LEAST TWO) IN BOBBIN-TYPE LI/SOC12 CELLS. THE NEW MECHANISM RESULTS IN A DECREASE IN CATHODE OVERPOTENTIAL (LESS LIC1) AND A SAFER LI/SOC12 CELL. ...

THE PROPOSED RESEARCH AND DEVELOPMENT WILL FOCUS ON THE DESIGN, CONSTRUCTION AND TESTING OF A LI/TIS(2) RECHARGEABLE CELL THAT WOULD BE USED IN THE BA5590/U CONFIGURATION. DESIGN TRADE-OFFS SUCH AS RATE CAPABILITY, CYCLE LIFE, CAPACITY AND COST WOULD BE CONSIDERED. TWO DESIGNS WOULD BE CHOSEN. SEVEN CELLS OF EACH WOULD BE BUILT AND TESTED. THE GOAL OF THE PROGRAM WOULD BE TO DEMONSTRATE A RECHARGE ...

THE DEVELOPMENT OF A LOW COST LASER BEAM WRITER THAT COULD GENERATE LITHOGRAPHIC PATTERNS AT HIGH SPEED WOULD BE OF SIGNIFICANT BENEFIT IN THE DEVELOPMENT OF HIGH-QUALITY, HIGH EFFICIENCY, BINARY OPTICAL COMPONENTS AND SUBSYSTEMS. IT IS PROPOSED TO INVESTIGATE A NEW CONCAPT FOR A HIGH EFFICIENCY IMAGING PROTOTYPE LASER BEAM WRITER AND DEVELOP A LABORATORY PROTOTYPE TO DEMONSTRATE ITS FEASIBILITY. ...

THIS PROPOSAL IS TO EXPERIMENTALLY INVESTIGATE THE SURFCE DISCHARGE TO PREIONIZED PULSED CARBON DIOXIDE LASERS. IN THIS APPROACH DIELECTRIC ELECTRODES ARE EMPLOYED FOR THE MAIN DISCHARGE, AND A SURFACE DISCHARGE ALONG THE SURFACE OF A DIELECTRIC ELECTRODE PREIONIZES THE GAS VOLUME PRIOR TO THE PRIMARY DISCHARGE. THIS SURFACE DISCHARGE APPROACH ELIMINATES THE NEED FOR A SEPARATE PREIONIZATION SOURC ...

WAVEGUIDE CO(2) LASERS HAVE FOUND MANY TACTICAL DOD APPLICATIONS RECENTLY. THE OUTPUT POWER OF A SINGLE WAVEGUIDE CO(2) LASER IS LIMITED TO ABOUT 40 W C.W. DUE TO GAIN SATURATION AND WAVEFRONT ABERRATIONS. IN THE SAME SIZE PACKAGE AN ARRAY OF WAVEGUIDES COULD BE EXCITED POTENTIALLY PRODUCING AN M X N INCREASE IN THE TOTAL OUTPUT POWER AND, IF THEY WERE PHASE-LOCKED, POTENTIALLY ALMOST AN (MXN)2 IN ...

IN THE PROGRAM PROPOSED HERE WE INTEND TO DEMONSTRATE COHERENT BEAM ADDITION OF TWO SINGLE-AXIAL-MODE ND LASERS OPERATING AT 1.06 MICRONS. THE SIGNIFICANCE OF THIS WORK IS THE DEMONSTRATION OF PHASE-LOCKING EMPLOYING A WELL-DEVELOPED SOLID-STATE LASER MATERIAL, WHICH HAS BEEN USED EXTENSIVELY AS A CW SOURCE AT 1 MICRON. MILITARY APPLICATIONS OF THIS TECHNOLOGY TO ADVANCED RANGING, TRACKING AND ACT ...

THE LACK OF A PROCESS TO DOPE ZNS(X)SE(1-X) FOR P-TYPE CONDUCTIVITY IS THE MAJOR OBSTACLE TO THE ADVANCEMENT OF DEVICE TECHNOLOGY BASED ON WIDE BANDGAP P/N HOMOJUNCTIONS. OF PARTICULAR IMPORTANCE ARE LIGHT-EMITTING DIODES AND INJECTION LASERS FABRICATED FROM ZNSXSE(1-X) WHICH OPERATE IN THE BLUE OR ULTRAVIOLET REGIONS OF THE SPECTRUM, ESSENTIAL FOR SOME TYPES OF SOPHISTICATED COMMUNICATION. SPIRE ...
