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 ...

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 ...

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 ...

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 ...

Large X-ray generators using gas fill loads are a key element in the DTRA simulator program. Consistent relative timing between the injection of the gas shell and the generator current pulse is crucial to producing consistent, high-yield x-ray pulses.To that end HY-Tech proposes replacing existing high voltage trigger pin technology, with a sensitive, all fiber-optic heterodyne interferometer ba ...

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). ...

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 ...
