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 ...

PLASMA OPENING SWITCHES (POS) ARE WIDELY USED FOR CURRENT COMPRESSION AND OWER AMPLIFICATION IN INDUCTIVE ENERGY STORE PULSE POWER SYSTEMS. FLASHBOARD PLASMA SOURCES ARE WIDELY USED AS PLASMA INJECTORS IN THESE POS'S. THE FLASHBOARD PLASMA IS PRODUCED BY SURFACE BREAKDOWN ON AN INSULATOR IN VACUUM. SINCE THE SURFACE CONDITIONS DEPEND ON THE PREVIOUS HISTORY, THE RESULTING PLASMA IS NOT UNIFORM, RE ...

The current distribution in plasma radiation sources is both a yardstick for measuring the coupling efficiency of the generator, and a means of studying the implosion dynamics of the load. Since the current distribution cannot be directly measured, it must be deduced from the magnetic field profile. Magnetic field distributions, based on the Faraday rotation of polarized laser light, are typical ...

THE VERY POLITICALLY SENSITIVE NATURE OF NUCLEAR WARFARE WOULD PRESUPPOSE THAT THE ABILITY OF THE COMMANDER TO PLAN FOR THE USE OF WEAPONS OF THIS TYPE WOULD CREATE THE NEED FOR A METHOD WHICH WOULD BE AS FOOL-PROOF AS POSSIBLE. EARLY WEAPONS WERE DESIGNATED STRATEGIC WEAPONS WHILE LATER DEVELOPED WEAPONS WERE CALLED TACTICAL. IT WAS WITH THE EVOLUTION TO TACTICAL WEAPONS THAT EXTENSIVE POSITIVE C ...

Using distributed interactive simulation (DIS) to conduct effective training, analyses, or mission support in a tactical nuclear weapons effects (NWE) environment requires realistic computer generated forces (CGF) that are sensitive to such effects. This level of sensitivity requires CGF to apply valid and reliable speed-accuracy measures of environmental effects on human performance within the D ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.

THE UNCERTAINTY IN MEASURING NEUTRON DOSE EQUIVALENT RATES RESULTS IN UNCERTAINTY IN ASSIGNMENT OF THE PROPER DOSE TO OCCUPATIONAL RECORDS AND CAN RESULT IN IMPROPER IMPLEMENTATION OF CONTROLS TO LIMIT THE EXPOSURE. A NOVEL PORTABLE NEUTRON SPECTROMETER IS PROPOSED WHICH WILL REDUCE THE UNCERTAINTY OF SUCH MEASUREMENTS TO LESS THAN 20%. MANYCOMPONENTS OF THIS DEVICE ARE COMMERCIALLY AVAILABLE. SYS ...
