KTECH PROPOSES TO DEVELOP OPTICAL HOPKINSON BAR PRESSURE GAUGES FOR MEASUREMENT OF AIRBLAST ON UNDERGROUND NUCLEAR EVENTS. THE BARS WILL BE MADE OF SINGLE CRYSTAL SAPPHIRE WHICH HAS A MEASURED YIELD STRENGTH IN EXCESS OF 10 GPA. THESE GAUGES WILL HAVE A RISE TIME OF ABOUT 2 US OF DATA. DURING PHASE I, WE WILL CONSTRUCT AND CALIBRATE A STRESS-INDUCED BIREFRINGENCE GAUGE (SIBG) WHICH WOULD NEED NO E ...

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 ...

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, ...

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 ...
