CAPESYM INC — Department of Homeland Security SBIR Phase I: Successful growth of novel halide scintillators SrI2:Eu and CLYC depends on a supply of hi

Description

Successful growth of novel halide scintillators SrI2:Eu and CLYC depends on a supply of highly pure precursor materials. CapeSym and SAFC will partner to provide holistic analysis of the nature of precursor impurities and their impact on scintillator performance. We will characterize light and heavy impurities, purify the material through novel techniques, and re-test outputs. In parallel we will conduct pricing analysis to estimate the volumes required to reach various cost targets. In this way we will begin to measure and correlate the relationship between impurities, scintillator yield, and processing costs. Anticipated benefits include:  increased understanding of binary-halide contamination issues  improved precursor processing techniques  improved scintillator performance  a roadmap for attaining precursor cost reduction
