Abstract
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 ELECTRICAL CONDUCTORS IN OR NEAR THE CAVITY, RESULTING IN AN EMP-PROOF GAUGE. IN PHASE II, WE WOULD VALIDATE THE GAUGE WITH ABOVE GROUND TESTS AND FLASE X-RAY AND E-BEAM MACHINES ON HE EVENTS, AS DISTANT IMAGE. A FULL NUCLEAR AIRBLAST APPLICATION WOULD OCCUR ON DIAMOND FORTUNE AS PHASE II. THIS RESEARCH IS INNOVATIVE IN THAT WE WILL DEVELOP INSTRUMENTATION FOR MEASUREMENT OF AIRBLAST IN UNDERGROUND CAVITY HEIGHT-OF-BURST EVENTS. UNLIKE OTHER INSTRUMENTATION, THE OPTICAL HOPKINSON BAR WILL BE IMMUNE TO UPSET BY SOURCE REGION ELECTROMAGNETIC PULSE.
