Gamma radiation detection has traditionally required single crystal materials that are difficult to produce consistently on an industrial scale. Agiltron has developed a new class of scintillator materials based on composites containing nanoparticles. These so-called nanocomposites exhibit radiation detection characteristics superior to currently available single crystal scintillators. In Phase I ...

Alphatech will develop & demo multirsolution statistical methods for the fusion of terrain elevation from existing 3-D terrain models and new elevation data. This fusion will produce new estimates of terrain elevation with accuracies, robustness, and update ratesprviously unachievable.

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 5x5 cm2, right cylinder, ...

We propose to develop a near-source model for the release of chemically reacting radionuclides. The model structure is based on an available code for reacting chemicals. The model will include interactive effects of nuclear transformation, chemical reaction, and plume physical motion. Such a model will provide fast and accurate predictions for the source characterization and transport of radion ...

A PROGRAM IS PROPOSED TO EVALUATE THE FEASIBILITY OF FORMING IMPROVED SIMOX MATERIAL BY CONTOURING THE ENERGY OF THE INCIDENT OXYGEN IONS. DURING THE IMPLANTATION PROCESS OF SIGNIFICANT AMOUNT OF SUBSTRATE MATERIAL IS REMOVED BY SPUTTERING. ALTHOUGH THE RANGE R(P) OF INCIDENT IONS REMAINS CONSTANT, TO FIRST ORDER, DURING THE IMPLANT, THE SPUTTERING AWAY OF THE SURFACE CAUSES INCIDENT IONS TO COME ...

The overall objective of the HSGR Program is to develop a high sensitivity military GPS receiver to provide reliable GPS navigation, under weak GPS signal conditions, to ground based military GPS users. Mayflower’s approach to meet this HSGR program objective is to design, develop and incorporate “high-sensitivity” signal processing enhancements (namely, Vector Tracking (VT) and Multi-bit GP ...

NZ Applied Technologies proposes to develop gallium nitride and aluminum gallium nitride high sensitivity avalanche photodetectors for solar blind ultraviolet wavelength applications. Solar blind ultraviolet avalanche photodetectors and position sensitive arrays with high sensitivity have broad applications in military, space, automotive, engine monitoring, flame detection, and environmental moni ...

SPIRE HAS RECENTLY DEMONSTRATED THAT SIMOX WAFERS OF SUFFICIENTLY HIGH QUALITY AND LOW DEFECT DENSITY TO SUPPORT BIPOLAR DEVICE APPLICATIONS CAN BE PRODUCED. TO ACHIEVE SUPERIOR QUALITY, HOWEVER, PRESENTLY REQUIRES PRODUCTION METHODS WHICH RESULT IN RELATIVELY HIGH COST. A RESEARCH PROGRAM IS PROPOSED WHICH WILL ESTABLISH THE FOUNDATION FOR LOWER COST, HIGHER THROUGHPUT PRODUCTION ALTERNATIVES WHI ...

A NUMBER OF NASA SATELLITES HAVE OBTAINED DATA WHICH CAN BE USED FOR DETERMINING AMBIENT ATMOSPHERIC DENSITY STRUCTURE PARAMETERS. AMONG THEM ARE THE ATMOSPHERIC EXPLORER SERIES -C, -D, AND -E) AND THE SOLAR MESOSPHERIC EXPLORER (SME). IT IS PROPOSED TO ANALYZE THESE DATA TO OBTAIN ESTIMATES OF ATMOSPHERIC DENSITY SPATIAL STRUCTURE PARAMETERS, POWER SPECTRAL DENSITIES ETC. THIS WILL PROVIDE INPUTS ...
