While many applications may have access to harvestable energy in the form of solar radiation (or other ambient light), wind, environmental vibration, or wave motion, not all do. In this proposal, RMD targets the most challenging applications, sensors that must operate for many months or years and which have undependable or no access to environmental energy. These sensors need a self contained, com ...

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 ...

High-resolution scintillation crystals and crystal arrays are important components of current and future handheld and arrayed detectors (used for DOD/DTRA applications), and scintillation spectrometers (routinely used in high energy physics research, medical imaging, diffraction, homeland security, nuclear waste clean-up, nuclear treaty verification and safeguards, and geological exploration). Un ...

Analysis of nuclear material samples in the field has many advantages over laboratory analysis. Laboratory analyses can be slow, involve increased expense, lead to additional waste generation and disposal problems, and may introduce errors due to sample degradation or mishandling. In situ analysis mitigates all of these problems. The specific aim of this project is the development of a truly por ...

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 ...

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 ...

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 ...
