IT IS PROPOSED TO DEVELOP A MANAGEMENT METHODOLOGY FOR PERFORMING TRADEOFF STUDIES OF NUCLEAR SURVIVABILITY OPTIONS FOR BATTLEFIELD SYSTEMS. THE PURPOSE FOR THE METHODOLOGY IS TO PROVIDE SYSTEMS MANAGERS (AND THEIR ADVISERS) A METHOD FOR ENSURING THE COST-EFFECTIVE SURVIVABILITY TECHNIQUES ARE INCLUDED IN THE SYSTEMS PLANNING IN EARLY STAGES. THE INTENT OF THE PROPOSAL IS TO SUPPORT IMPLEMENTATION ...

WITH THE VERY WIDE RANGE OF APPLICATIONS OF ACOUSTO-OPTIC SIGNAL PROCESSING AND OPTICAL COMMUNICATION IN NUCLEAR WARFARE ARMS, THE NEED EXISTS TO EVALUATE OPTICAL SIGNAL PROCESSORS COMPONENTS IN BOTH REAL AND SIMULATED NUCLEAR ENVIRONMENTS. ALSO THE USE OF ACOUSTO-OPTIC DEVICES FOR A COMMERCIAL SPACE APPLICATIONS IS VERY PROMISING DUE TO ITS HIGH SPEED, LOW POWER CONSUMPTION AND LIGHT WEIGHT. IN P ...

THE CONTRACTOR HAS PATENTED TECHNOLOGY FOR A UNIQUE PROCESS THAT DIRECTLY CONVERTS AN ACOUSTIC SIGNAL INTO A VISIBLE ONE IN REAL-TIME WITHOUT ELECTRONIC CIRCUITRY. THIS RELIES ON THE ACOUSTO-OPTICAL PROPERTIES OF A CONTINUOUS LAYER OF LIQUID CRYSTAL THIN FILM LAYER WHICH SERVES AS BOTH THE SENSOR AND THE DISPLAY. THE IMAGE CAN BE VIEWED DIRECTLY BY MEANS OF CCD CAMERA. HOLOGRAPHY PROVIDES FOR BOTH ...

ACCURATE CHEMICAL ANALYSIS AT POTENTIAL SITES OF CHEMICAL WARFARE (CW) AGENT MANUFACTURE, STORAGE OR USE IS OF GREAT VALUE FOR DETERMINATION OF CW TREATY VIOLATIONS AND FOR VERIFICATION OF DESTRUCTION OR REMOVAL OF CW AGENT SYSTEMS. RECENT DEVELOPMENTS IN HAND- HELD GAS CHROMATOGRAPHY/ION MOBILITY SPECTROMETRY (GC/IMS) FOR DIRECT AIR MONITORING HAVE ILLUSTRATED THE POTENTIAL OF THIS TECHNIQUE FOR ...

A GOOD MODEL FOR PREDICTING THE CONDUCTION AND OPENING CHARACTERISTICS OF PLASMA OPENING SWITCHES IS REQUIRED IF SWITCH- ES CURRENTLY IN USE ARE TO BE SCALED UP TO THE CURRENT AND VOLTAGE RATINGS REQUIRED BY THE FAMILY OF THREAT SIMULATOR. EMPIRICAL VERIFICATION OF THE NUMEROUS MODELS WHICH HAVE EVOLVED AROUND DIFFERENT CONDUCTION PROCESSES HAVE MET WITH LIMITED SUCCESS BECAUSE SWITCH CHARACTERIST ...

Large X-ray generators using gas fill loads are a key element in the DTRA simulator program. Consistent relative timing between the injection of the gas shell and the generator current pulse is crucial to producing consistent, high-yield x-ray pulses.To that end HY-Tech proposes replacing existing high voltage trigger pin technology, with a sensitive, all fiber-optic heterodyne interferometer ba ...

N/A

THE DAMAGING EFFECTS OF NUCLEAR AIRBLAST, THERMAL AND PROMPT RADITION, AND EMP ON EXPOSED EQUIPMENT AND STRUCTURES ARE WELL KNOWN. AN ADDITIONAL, LESS WIDELY RECOGNIZED BUT POTENTIALLY SERIOUS NUCLEAR EFFECT IS THAT OF AIRBLAST-INDUCED SHOCK (ABIS). EQUIPMENT MOUNTED INSIDE AN ENCLOSED SPACE CAN BE EXPOSED TO LARGE INDUCED VELOCITIES AND ACCELERATIONS, PRIMARLY IN THE HORIZONTAL DIRECTION. THE INT ...

NEW MATERIALS DEVELOPED BY QUANTEX IN 1985 SHOW GREATLY IMPROVED PROPERTIES FOR APPLICATION TO OPTICAL COMPUTERS. A CLASS OF ELECTRON TRAPPING (ET) MATERIALS HAS BEEN GENERATED WHICH, UPON TRAP-CHARGING WITH VISIBLE LIGHT, MAINTAINS FILLED TRAPS INDEFINITELY. NEAR-INFRARED LIGHT (800 NM TO 1200 NM) TRIGGERS TRAPPED ELECTRON RELEASE, RESULTING IN EMITTED VISIBLE LIGHT. SUCH OPERATION APPEARS IMPERV ...
