This program will provide an improved understanding of the effects of atmospheric moisture on hazardous material and define methods to better model these effects in the DTRA HPAC model. The work will evaluate the interaction of moisture and hazardous material in the HPAC model based on two levels of coupling the transport equations for hazardous material and moisture. These evaluations will be com ...

Penetrating radiation holds the greatest promise as a non-intrusive means of destroying biological and chemical agents inside sealed containers, if the appropriate form is used. There are two recognized means including exposure to neutrons or application of pulses of gamma rays. Because of the pervasiveness of neutrons and the extremely large threat of collateral damage to humans, neutrons are onl ...

Nuclear weapons effects simulators depend upon capacitor banks for storage and delivery of energy for the radiation sources. Power conditioning elements are typically located in the power flow chain between the storage capacitors and the radiation sources, and these elements generally constitute a major portion of the overall cost of the simulator facility. Low inductance capacitors offer the po ...

The nuclear weapons community has traditionally focused on the next generation or level of weapon capability complimented by gathering and analysis of actual test data. Now, with the cessation of actual weapons testing, there is an increased need to use the actual test data in modeling techniques to better understand the phenomenology and potential effects of nuclear weapons. The first phase of ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...

Mission Research Corporation proposes the development of a unique FPGA (field programmable gate array) for applications in space and other military and civilian environments requiring the versatility of reconfigurability with retention of the configuration in an unpowered state. The FPGA will be capable of being configured once and retaining that configuration for a minimum of 10 years even with ...

We propose, in Phase I and Phase II, to build an X-ray simulator capable of easy transportation between sites which can be built for a low cost (

CURRENT ATTEMPTS TO USE THE PLASMA OPENING SWITCH (POS) FOR DECADE HAVE NOT YET BEEN ENTIRELY SUCCESSFUL DUE TO THE APPARENT INABILITY OF THE SWITCH TO OPEN EFFICIENTLY TO A HIGH-IMPEDENCE LOAD. RESEARCH DIRECTED TOWARD IMPROVING THE PERFORMANCE OF THE POS IN THE LONG-CONDUCTION TIME REGIME HAS BEEN FRUSTRATED BY THE INABILITY OF COMPUTATIONAL TOOLS TO OPERATE IN THE PARAMETER REGIMES OF INTEREST ...

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 ...
