A worldwide network of radionuclide monitoring stations has been established to monitor radioactive fall-out from nuclear tests. These stations sample the air for radioactive particulates and Xenon on a daily basis. This project is to develop a softwaresystem to determine the location, timing, and yield of nuclear events and their corresponding estimation probabilities using the sampled data from ...

NOVA Scientific will demonstrate a large-area/low-cost neutron detection system having high detector quantum efficiency and high signal-to noise ratio. The approach utilizes an embedded neutron absorber in a solid state detector, utilizing known processingtechnology. The system detects fissionable materials by converting the neutron signal into a large electron pulse. The unit is light for field d ...

The detection and identification of threats due to the proliferation of weapons of mass destruction (WMD) or associated special materials is of increasing importance to national security. The goal of the proposed program is to develop a man-portable,battery-operated gamma-ray spectrometer for the high-resolution characterization of the hidden contents of sealed containers, including nuclear, radi ...

NEMP (Nuclear Electro-Magnetic Pulse), lightning strikes, high powered EMI (Electro-Magnetic Induction), or ESD (Electro-Static Discharge) can impress high transient voltages on wires connecting to electronic modules. These transients are potentially destructive to aircraft electronic components and can result in system failures. To eliminate or substantially reduce the effects of transients on ...

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 ...

SIMOX (Separation by IMplanted Oxygen) technology achieves total dielelectric isolation of active device regions from the substrate and reduces the collection path for ionized charges via the built-in buried oxide which restricts charge movement. Advances in SIMOX technology include radiation hardened memories and gate arrays for space applications, ULSI DRAMS for low voltage operation, thin film ...

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 ...

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 (

An optical sensor capable of producing 3-dimensional time resolved density maps characteristic of shock wavefronts at Mhz sampling rates is proposed. Each map is obtained from simultaneous measurements obtained with a novel refractometer capable of measuring integrated density fluctuations in air to better than 1 part in 3500 per centimeter path length at 1Mhz with good signal to noise (S/N=10). ...
