UNDER THIS EFFORT, WE WILL DEVELOP A PORTABLE MEMORY TESTER UNIQUELY DESIGNED TO PERFORM THE TYPES OF TESTS REQUIRED FOR RADIATION EFFECTS CHARACTERIZATION. SPECIFICALLY, IT WILL PERFORM TESTS TO CHARATERIZE SINGLE EVENT PHENOMENA (SEP), TOTAL DOSE IONIZING EFFECTS, DOSE RATE, AND RAPID ANNEALING PHENOMENA. IT WILL COMBINE KEY FEATURES OF GENERAL PURPOSE ASIC TESTERS AND DEDICATED MEMORY TESTERS R ...

DIGITAL OPTICAL COMPUTING HAS EVOLVED TO THE POINT WHERE VIABLE ARCHITECTURES HAVE BEEN DESCRIBED IN DETAIL. HUNDREDS OF PAPERS ARE PUBLISHED AND SEVERAL TOPICAL CONFERENCES ARE HELD ANNUALLY ON THE SUBJECT. HOWEVER, FEW DEMONSTRATIONS HAVE BEEN REPORTED OF ACTUAL OPERATING SYSTEMS DUE TO THE UNAVAILABILITY OF AN "IDEAL" OPTICAL LOGIC GATE HAVING: OPTICAL GAIN, CASCADABILITY, HIGH ON/OFF CONTRAST, ...

LOW-ENERGY LASER TECHNOLOGY HAS THE POTENTIAL TO SIGNIFICANTLY IMPROVE THE EFFENCIENCY AND EFFECTIVENESS OF NUCLEAR WEAPONS SECURITY OPERATIONS. SUCH LASERS, EMPLOYED IN EITHER AUTOMATED OR REMOTELY MANNED CONFIGURATIONS, CAN SUPPLEMENT CURRENT PHYSICAL SECURITY MEASURES BY PROVIDING THREE NON-LETHAL RESPONSE OPTIONS: (1) WARN INTRUDERS THAT THEY HAVE BEEN DETECTED AND ARE ENTERING A SECURE AREA, ...

EFFICIENCY OF HIGH POWER UV-PHOTOIONIZED EXCIMER AND CO2 LASERS HAVE BEEN LIMITED BY THE POWER CONSUMED IN THE PHOTOIONIZED SOURCE. THE USE OF SCREEN CATHODES PRESENTS THE PROBLEM OF MECHANICAL STRENGTH. SCREEN CATHODES MADE OUT OF WIRE MESH ARE EXCELLENT LIGHT TRANSMITTERS BUT LACK MECHANICAL STRENGTH, NOT TO MENTION THAT THEY CAN BE DESTROYED BY ARCING. CATHODES MADE OUT OF PERFORATED ALUMINUM O ...

FUTURE SYSTEMS EMPLOYING PULSED POWER TECHNOLOGY WILL REQUIRE SIGNIFICANT IMPROVEMENT IN THE CURRENT STATE OF THE ART OF PULSED POWER DEVICES. IN PARTICULAR, HIGH VOLTAGE REPETITIVE SWITCHES ARE NEEDED WHICH SIGNIFICANTLY GO BEYOND THE PRESENT CAPABILITIES OF KNOWN SWITCHES. FUTURE SWITCHING TECHNOLOGY NEEDS TO HANDLE VOLTAGES RANGING FROM HUNDREDS OF KILOVOLTS TO MEGAVOLTS, HUNDREDS OF KILOAMPERE ...

THE TACITRON IS A HIGH TEMPERATURE (300 - 1500 DEGREES C) SWITCH THAT CAN SWITCH HIGH CURRENTS (>10'S OF AMPERES PER SQUARE CM OF SWITCH ELECTRODE AREA) AND HIGH VOLTAGES (>200 VOLTS) AT SWITCHING SPEEDS IN THE 10'S TO 100'S OF KILOHERTZ. THIS SWITCH IS FULLY CONTROLLABLE SO IT CAN PERFORM THE SAME FUNCTIONS AS MANY OF THE SEMICONDUCTOR DEVICES (TRANSISTORS, DIODES, THYRISTORS) EXCEPT THAT THE TAC ...

DEVELOPMENT OF A HIGH FIDELITY, HIGH ENERGY DENSITY WATER SHOCK SIMULATOR APPEARS FEASIBLE. MISSION RESEARCH CORPORATION (MRC), WITH THE ASSISTANCE OF THE NEW MEXICO ENGINEERING RESEARCH INSTITUTE (NMERI), PROPOSES TO DEVELOP AN ELECTRICAL WATER SHOCK SIMULATOR WHERE AN ELECTRICAL DISCHARGE ACROSS A WELL DEFINED ELECTRODE GAP WILL PRODUCE A HOT PLASMA EXPANSION WHICH RESULTS IN A FAST RISE PRESSUR ...

THE APPLICATION OF HIGH TEMPERATURE SUPERCONDUCTORS IS SEVERELY LIMITED BY THE LOW CURRENT DENSITIES ACHIEVABLE IN BULK MATERIALS, SUCH AS Y1BA2CU3O(7-X), OR 123 FOR SHORT. THE LARGE CURRENT DENSITIES OBSERVED WITHIN INDIVIDUAL GRAINS (AND IN THIN FILMS) ARE REDUCED BY "WEAK LINKS" AT THE GRAIN BOUNDARIES, CAUSED BY MISALIGNMENT OF THE ANISOTROPIC GRAINS AND BY INSULATING IMPURITY PHASES. SOME OF ...
