The Ktech Team proposes a feasibility study of a fuel/air driven flux compression power unit (FCPU) for electric guns. Through variations of inductance gradients and through changes in scale, the proposed technology will be applicable to both electrothermal/chemical and electromagnetic guns. In the Phase 1 effort, we develop simulation models to predict the performance of the flux compression po ...

Lexitek proposes to develop an imaging gamma-ray detector with 1024 x 1024 pixels for arms control verification. The proposed detector significantly enhances the resolution of fissionable material distribution without compromising energy resolution. The detector consists of a scintillating crystal and associated sensors which determine the energy and position of the scintillation with high spat ...

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 ...

CREATION OF BURIED INSULATING LAYERS IN SILICON WAFERS BY HIGH DOSE OXYGEN IMPLANTATION (SIMOX) HAS GAINED SIGNIFICANT ATTENTION IN THE LAST TWO YEARS. THE SIMOX TECHNOLOGY IS POSITIONED TO BE A PRIME CONTENDER IN THE SILICON-ON-INSULATOR (SOI) ARENA MAINLY BECAUSE OF THE INHERENT RELIABILITY/REPRODUCIBILITY OF THE ION IMPLANTATION TECHNOLOGY. ONE OBSTACLE TO BROADER USE OF THE SIMOX MATERIAL IS T ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP AN IMPROVED DIFFERENTIAL PRESSURE GAGE FOR DETERMINING DYNAMIC PRESSURE WITHIN BLAST AND SHOCK WAVE FLOWS WHERE THE FLOWS ARE SUBSONIC. DERIVATION OF DYNAMIC PRESSURE FROM A MEASUREMENT OF THE DIFFERENCE BETWEEN STAGNATION PRESSURE AND SIDE-ON OR STATIC PRESSURE REQUIRES USE OF THE SIDE-ON PRESSURE RECORD TO CORRECT FOR COMPRESSIBILITY EFFECTS. CURRENTLY ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...
