WE PROPOSE A PROTOTYPE ULTRA-SENSITIVE, FAST, COMPACT, AND RELIABLE FIBER OPTIC BASED MAGNETIC FIELD SENSOR PARTICULALY SUITED FOR OPERATION IN ENVIRONMENTS APPROPRIATE FOR NUCLEAR WEAPON SIMULATION AND TESTING. THE DESIGN WILL TAKE ADVANTAGE OF AN INNOVATIVE WHICH WILL PERMIT REMOTE MEASUREMENTS OF MAGNETIC FIELDS WITH SIGNIFICANTLY ENHANCED SENSITIVITY AND RELIABILITY OVER PREVIOUS DEVICES. ALTH ...

THIS STUDY WILL RESEARCH, ANALYZE, AND ASSESS NEW CONCEPTS FOR THE SURVIVABILITY OF THE TNF WHICH WILL BE REQUIRED IN THE NEAR FUTURE AS A RESULT OF THE ONGOING PROCESS OF DEMOCRATIZATION OF THE COUNTRIES OF EASTERN EUROPE. THE MOST LIKELY POLITICAL DEVELOPMENT OVER THE NEXT 10 YEARS WILL BE THE STEADY MOVE TOWARD DEMOCRACY BY THESE COUNTRIES. AS A RESULT, THERE WILL BE A STEADY REDUCTION IN MILIT ...

OPTICAL EFFECTS OF NUCLEAR EXPLOSIONS, PARTICULARLY MULTIBURST INTERACTIONS AND INFRARED STRUCTURE DUE TO FIREBALL TURBULENCE, ARE OF CURRENT INTEREST. THE BEAU GESTE EXPERIMENT DATA BASE IS UNIQUE IN INCLUDING HOTWIRE ANEMOMETRY, IR VIDEO RECORD, AND VISIBLE LIGHT PHOTOGRAPHS FOR SINGLE AND MULTIPLE DETONATIONS. PRI PROPOSES TO DIGITIZE SELECTED IR, VISIBLE AND ANEMOMETRY DATA, OBTAIN POWER SPECT ...

AN EXPERIMENT IS PROPOSED TO DEMONSTRATE THAT TRANSIENT X-RAY RADIATION FROM THE PHYSICS INTERNATIONAL PULSERAD 1150 FLASH X-RAY MACHINE WILL CAUSE A REPRESENTATIVE HIGH TEMPERATURE SUPERCONDUCTING (HTS) DEVICE TO MALFUNCTION BY REVERTING TO NORMAL CONDUCTIVITY. INTEREST IN THIS PHENOMENON IS MOTIVATED BY THE ANTICIPATED INCORPORATION OF HTS THIN FILM TECHNOLOGY IN DEFENSE ELECTRONICS, ESPECIALLY ...

FILMS OF RADIOCHROMIC DOSIMETRY MATERIAL COUPLED WITH FILTERS PROVIDE BOTH DOSE AND SPECTRAL INFORMATION ON NUCLEAR TESTS, A SUBSTANTIAL MONITORING CAPABILITY. THE DIAGNOSTIC DEVICES, HOWEVER, OCCUPY SUBSTANTIAL VOLUME; THE MATERIALS BLEACH DUE TO RADIATION DAMAGE AND ARE PRONE TO DYE MIGRATION. ALL CONSTITUTE SIGNIFICANT LIMITATIONS. A FIBER OPTIC DOSIMETER IS PROPOSED FOR UNDERGROUND NUCLEAR TES ...

MISSION RESEARCH CORPORATION (MRC) PROPOSES TO BUILD HF-NEPS, AN HF CHANNEL SIMULATOR FOR BENCH-TOP TESTING OF HF TRANSCEIVERS. THE SIMULATOR WOULD DISTORT AND DELAY ANALOG HF SIGNALS AS IF THESE HAD PASSED THROUGH IONOSPHERIC REGIONS DISTURBED BY HIGH ALTITUDE NUCLEAR EXPLOSIONS. THE FREQUENCY SELECTIVE HF CHANNEL MODEL UNDERLYING THIS HARDWARE SIMULATOR WILL ACCOMMODATE THE HF CHANNEL SPECIFICAT ...

FRATRICIDE, FALLOUT, AND AIRCRAFT HAZARD ZONES ARE INFLUENCED BY NUCLEAR DUST CLOUDS. THE DUST MASS LOFTED FROM OPEN AREAS IS WELL ESTIMATED; THE AMOUNT LOFTED FROM URBAN AREAS IS NOT ESTIMATED AT ALL. SINCE MANY TARGETS ARE LOCATED IN URBAN AREAS, THE ADDITIONAL DUST LOFTED MAY BE SUBSTANTIAL. IN THIS SBIR EFFORT, WE PROPOSE TO DEVELOP A UNIQUE AND INNOVATIVE SERIES OF EXPERIMENTS THAT WILL LEAD ...

ESTABLISH DESIGN CRITERIA FOR, AN OPTICAL PROBE TO MEASURE THE DUST LOFTED BY THE SHOCK WAVE DURING A NUCLEAR BLAST WAVE SIMULATION. DUST DENSITY IS DETERMINED FROM THE REDUCTION IN INTENSITY OF LIGHT PROJECTED OVER AN INTERROGATION PATH TRANSVERSE TO THE FLOW. USE OF A SIMPLE LIGHT SOURCE AND DETECTOR WITH FIBER OPTIC TRANSMISSION LINES PRODUCES AN INEXPENSIVE RUGGED INSTRUMENT WHICH CAN BE DEPLO ...

The ability to collect data for conventional munitions in conditions of increasing acceleration and duration for hard target penetration is needed. Survivability and functionality of an electronic data recorder exposed to these acceleration levels (up 120,000 g) and shock loads is necessary as a result of higher velocity weapons and the use of precursor shape charge warheads to soften the target ...

The problems addressed by this proposal are related to the need for fast running models (FRMs) that predict damage imparted to structural components composed of UHPC materials, particularly slabs, by munitions related to their penetration and detonation. These FRMs are also to provide the resulting residual capacity of the component and account for the effects of multiple strikes. The FRMs need ...
