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 ...

A radiation hardened via-configurable analog array (RHVCAA) is proposed to provide a rapid prototyping mixed signal platform for implementing radiation hardened and high performance custom analog system designs. In phase I the feasibility of implementing RHVCAAs was investigated. Existing Triad semiconductor VCAA technology was assessed to determine modifications required to comply with radiation ...

The physical phenomena that dominates the use of submillimeter (SMM) spectra for the analysis of missile intercepts is the rapid cooling of the post-intercept gas and debris field and its impact on the SMM spectral signatures and post-impact chemistry. It is likely that the initial high temperatures and density will result in a molecular soup that is much more complex than the atomic mixtures tha ...

The work proposed here seeks to produce CZT substrates with superior qualities aimed at improving the performance of MCT detectors used in infrared detectors. The proposed work promises to overcome one of the major causes of dislocation formation in MCT structures.

The goal of this program is to produce large area Cadmium Zinc Telluride (CZT) substrates for growth of Mercury Cadmium Telluride (MCT) films for application in IR Focal Plane Arrays. Two growth processes will be pursued in this program. The grown CZT crystals will be processed into substrates. MCT films will be grown on these substrates and their properties will be characterized.

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 ...

Missile defense remains a crucial component for protecting the United States and her allies from potential long-range threats. Modeling and simulation (M&S) is recognized by the Missile Defense Agency as a key enabling technology supporting Warfighters and analysts in ballistic missile defense system (BMDS) design, testing, performance assessment, training, wargaming, and system acquisition. The u ...

Corvid Technologies is pleased to offer this SBIR Phase II proposal. In the proposed effort, we will extend the high-fidelity analysis processes demonstrated during Phase I to generate large-scale, production-quality databases for intercept debris fragments. Our approach utilizes an innovative combination of high-fidelity computational fluid dynamics for a broad range of flow conditions, high-pe ...

The impact of metal whiskers on the reliability of electronics has been exacerbated by environmentally-driven efforts to eliminate lead from tin plating and solders. Even exempt applications, such as military, are affected due to COTS. Foresite, Inc., a consultant, laboratory and test equipment development company, has a goal for the subject research, in collaboration with Purdue University, to ...

A compact "dual-mode" 1-micron laser source will be developed that can be switched "on the fly" between a high-pulse-rate, lower-energy emission mode and a lower-pulse-rate, high-energy emission mode. Pulse duration will be less than 10 ns and beam quality will be near-diffraction-limited.
