Certain lanthanide halides have significantly higher light output than NaI:Tl, the comparison standard for scintillators, plus other important properties, including fast decay times and excellent proportionality. Unfortunately, lanthanide halides grown by traditional melt processes have high production costs and limited availability. Crystals are usually limited to about 5 cm x 5 cm, right cylinde ...

It is proposed to develop a novel process for growth of high quality CZT crystals for nuclear detection applications. Currently the THM process is the technology of choice for production of high quality CZT crystals. This process, however, suffers from extremely low growth rates. The development effort proposed here will seek to increase the crystal growth rate by 5-10 times the current levels ...

KaZaK Composites, Inc. proposes to work with Oak Ridge National Labs and Bombardier Transportation to design and develop a lightweight, cost effective pultruded composite rail car roof. Including a novel Phase Change material core. The program goal will be the design of a composite sandwich panel replacement for the current welded aluminum roof structure of passenger rail cars. Composite design ...

High energy density capacitors are needed to provide load flexibility to fuel cells as hybrid power supplied for a variety of WMD sensors and detectors. New materials/manufacturing processes are needed to make these electrical power systems man portable. To develop high performance supercapacitors with fast recharge and high discharging rate electrode materials should have very high surface area. ...

Three nuclides are especially useful in detecting thermalized neutrons: helium-3, lithium-6 , and boron-10. Since current demand will deplete reserves of helium-3 in roughly two years, there is a large desire to develop detectors that have the capacity to replace helium-3 tubes. In this proposal we spell out our plan to adapt Neotron''s already developed fission neutron detector into a high effic ...

In Phase I, we developed a suite of algorithms for the detection and classification of motorcycle and bicycle using IR LED stereo camera, LWIR thermal camera, and microphone. Test results using real data collected at streets have shown an excellent performance of this system. In Phase II, we will further improve the system developed and focus on the system performance issues in terms of near 100 ...

Large Scale Field Tests of MigmaMidblockTM Under FHWA SBIR Phase I/II funding, we have developed a product, MigmaMidblockTM, using stereoscopic technologies for the pedestrian detection at mid-block crossings and signalized intersections. It has been fielded at a mid-block crossing at Phillips Academy located in Andover, MA. This product can trigger the beacon flashers once pedestrians (i.e., h ...

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 ...
