Until now gamma radiation detection has required large single crystals of sensitive materials that are difficult to produce consistently on an industrial scale. In collaboration with a research group at the University of Texas at Arlington, Agiltron proposes to develop a new class of nanocomposite scintillator materials. The radiation detection characteristics of the synthetic nanoparticles in the ...

The objective of this program is to develop a capability for a field deployable proton accelerator system that can generate high energy protons to neutralize concentrated masses of bio-agents held in steel storage drums. The Phase I research and development will involve conceptual design of a compact field deployable proton accelerator capable of delivering protons of energy >100 MeV, and studying ...

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 ...

In Phase I, the Peerless team developed an approach for an innovative wizard driven, turn-key, system that can be used by inexperienced operators to quickly design new sensor networks and evaluate existing sensor networks for the protection against and detection of CB agents within public structures. For Phase II, Peerless will conduct three development spirals to build the prototype system, valid ...

NOVA Scientific proposes Phase II development of a solid-state, high-efficiency neutron detection alternative to 3He gas tubes employing neutron-sensitive microchannel plates (MCPs) containing 10B and/or Gd. This program supports the DNDO development of technologies designed to detect and interdict nuclear weapons or illicit nuclear materials. This solid-state neutron detector would permit operati ...

Proliferation of nuclear weapons is a serious threat in the world today. One way to determine the presence of nuclear weapons is to detect neutrons emitted by special nuclear material(SNM) such as highly enriched uranium and weapons grade plutonium. The purpose of this project is to develop improved solid state neutron detectors from CVD diamond for homeland security applications. Phase I work wil ...

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 PHASE I EXPERIMENTAL EFFORT WILL DEMONSTRATE THE FEASIBILITY OF A FIELD WORTHY GROUND MOTION SENSOR TO REPLACE PIEZO-ELECTRIC ACCELEROMETERS FOR CONVENTIONAL EXPLOSIVES AND NUCLEAR TESTING. THE OUTPUT SIGNALS OF PIEZO-ELECTRIC ACCELEROMETERS MUST BE INTEGRATED TWICE TO DETERMINE GROUND MOTIONS. THIS PROCESS REDUCES SYSTEM ACCURACY AND MEASUREMENT BANDWIDTH. ADDITIONALLY, AS PIEZO-ELECTRIC SENS ...

Non contact trace explosives detection has not been comparable to results obtained from wipe sampling. Many issues, including finding a method to release particles from a surface, efficient particle and vapor transport, and limited particle and vapor trap collection efficiency have all limited the process. Other related issues have included cost of ownership, ease of contamination removal, and com ...

Gamma-ray spectrometers consisting of inorganic scintillators coupled to optical detectors such as photomultiplier tubes (PMTs) are an important element of the systems that are used to monitor and prevent the spread of special nuclear materials. Two very important requirements for the scintillation detectors used as gamma-ray spectrometers in homeland security monitoring include high sensitivity a ...
