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 ...

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 (

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 ...

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 ...

The Defense Nuclear Agency hase undertaken several related programs to develop new technologies for countering the proliferation of weapons of mass destruction, including weapons which disperse dry spore biological agents. These initiatives require an increased understanding of the response o fthese agents and their surrogates to the environments generated by various weapons, including penetratin ...

Pulsed power systems for electric armament and compact weapons require increasingly smaller energy delivery systems and higher levels of reliability and component safety. Although new capacitor technologies such as double layer and electrostatic supercapacitors promise energy densities higher than 10J/cc, liquid impregnated film dielectrics with energy densities of 2.5J/cc, continue to be the sta ...

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 ...
