Title: R200 Spectrometer with Frisch-grid Cadmium Zinc Telluride (CZT)

Abstract

The goal of this project is to demonstrate an engineering prototype of a gamma ray spectrometer that uses Cadmium Zinc Telluride (CZT) in a configuration comprised of an array of position-sensitive virtual Frisch grid (PSVFG) detectors and show its capability to perform functions that would be useful to the IAEA. The detectors should achieve energy resolution of 2-3% at 200 keV and <1% at > 662 keV (at temperature <30°C), thereby outperforming all hand-held instruments currently in use other than cryogenically cooled germanium. BNL is working to transfer the technology to an industrial partner so that robust, fieldable instruments can be manufactured.
