THE EMERGING IMPORTANCE OF NUCLEAR-WEAPON AND DIRECTED ENERGY WEAPON (DEW) EFFECTS TESTING IN THE SOFT X-RAY REGIME HAS HIGHLIGHTED THE NEED FOR A ROBUST, ACCURATE AND RELIABLE SOFT X-RAY SPECTROMETER THAT WILL MEASURE FLUENCE INCIDENT ON UGT TEST-ARTICLES. THE NEW LAYERED SYNTHETIC MICROSTRUCTURE (LSM) X-RAY INTERFERENCE MIRROR TECHNOLOGY IS PROPOSED AS THE BASIS FOR A SPECTROMETER RESPONSIVE TO ...

THE PROPOSED FIBLOC SENSOR PROVIDES AN ECONOMIC MEANS TO PROTECT, LITERALLY, MILES OF A PREFERRED PERIMETER REGION AGAINST UNAUTHORIZED INTRUSIONS. THE OPTICAL FIBERS EMPLOYED INT HE FIBLOC SENSOR PROPAGATE CW OR PULSED INFRARED LIGHT SIGNALS WHOSE TRANSMISSION AND/OR REFLECTION SENSITIVITY IS AFFECTED BY MECHANICAL PRESSURE SUCH AS WOULD BE PRODUCED BY THE DISTENSION OF SURFACED MOUNTED FIBERS AL ...

DEVELOPMENT OF AN INNOVATIVE AND ECONOMICAL EXPERIMENTAL METHOD IS PROPOSED WHICH CAN PROVIDE THE BASIC BEHAVIOR DATA NECESSARY TO MEET THE DNA OBJECTIVE OF PROVIDING ADEQUATE ANALYSIS, DESIGN AND ASSESSMENT METHODS FOR MINIMALLY HARDENED TUNNELS. THIS DEVELOPMENT IS ACCOMPANIED BY ANALYSIS CAPABLE OF REPRESENTING THE COMPLEX INELASTIC MATERIAL BEHAVIOR OF THE ROCK MASS AND OF REPRESENTING SIMPLE ...

HIGH ALTITUDE NUCLEAR THREATS GENERALLY REQUIRE THE USE OF OVERLAYS/UNDERLAYS TO ACHIEVE THE NUCLEAR SURVIVABILITY REQUIREMENTS OF ADVANCED REENTRY VEHICLES (RVS). MATERIALS AND FABRICATION PROCESSES EXIST THAT WITH SOME MINOR VARIATIONS SHOULD PRODUCE A HEATSHIELD MATERIAL THAT CAN EITHER ELIMINATE THE NEED FOR, OR REDUCE THE REQUIREMENTS OF, OVERLAYS/UNDERLAYS. THE PROPOSED MATERIAL, RELATIVE TO ...

THE OBJECTIVE OF THIS RESEARCH IS TO ACHIEVE GREATER SENSITIVITY, RUGGEDNESS AND EASE OF USE OF ALPHA MEASURING DEVICES IN POTENTIALLY HARSH FIELD ENVIRONMENTS BY APPLYING THIN FILM DIAMOND TO THE INSTRUMENT DETECTOR FACE. TO ACHIEVE THIS OBJECTIVE WE WILL ATTEMPT TO COAT SILVER ACTIVATED ZINC SULPHIDE WITH DIAMOND USING CHEMICAL VAPOR DEPOSITION TECHNIQUES DEVELOPED BY THE COMPANY AND APPLY AN AP ...

THE EXTENSION OF A PHYSICAL MODELING TECHNIQUE UTILIZING ROCK-SIMULANTS AND SIMULATED BLAST LOADING TO MODEL PROPAGATION OF DILATIONAL WAVES THROUGH FLUID-SATURATED FRACTURED ROCK MASSESS WILL BE EVALUATED. ROCK-SIMULANTS, WITH NEGLIGIBLE MATRIX PERMEABILITY, WILL BE DEVELOPED FOR SPECIMEN PREPARATION. A STEP-BY-STEP CASTING PROCEDURE WILL BE EMPLOYED TO SIMULATE JOINTING AND BEDDING PLANES. ATTEM ...

THIS DOCUMENT PROPOSES RESEARCH ON THE FABRICATION OF A FAMILY OF EMP HARDENED CONNECTORS AND CABLE HARDWARE FOR AIRCRAFT AND SHIPBOARD APPLICATIONS. THESE CONNECTORS AND CABLE HARDWARE WOULD SUPPRESS EMP TRANSIENTS THROUGH THE INTEGRAL INCORPORATION OF A THIN FILM, HIGH SPEED, HIGH CURRENT OVONIC THRESHOLD SWITCH (OTS). CABLES AND HARDWARE OF THIS TYPE WOULD SIGNIFICANTLY INCREASE THE SURVIVABILI ...

THE SAFE DESIGN OF DEEP MISSILE BASING STRUCTURES SUBJECTED TO STRESS TRANSIENTS GENERATED BY SURFACE DISTURBANCES SUCH AS NUCLEAR OR CONVENTIONAL EXPLOSIONS IS A VERY IMPORTANT PROBLEM FOR J.S. NATIONAL SECURITY INTEREST. THE PROPAGATION OF SURFACE DISTURBANCES THROUGH INHOMOGENEOUS, JOINTED, FRACTURED, AND LAYERED GEOLOGIC MEDIUM OF THE INFINITE DOMAIN IS A VERY COMPLEX PROBLEM ESPECIALLY NEAR D ...
