Advances in CdZnTe Detectors for Safeguards

摘要

In this paper, we will describe recent developments in CdZnTe detector technology, includingmethods to improve the performance of detectors at high ambient temperature, miniature electronicsfor spectroscopy, and analytical software for portable detectors. A large-volume, portable detectionprobe consisting of an array of coplanar grid detectors is demonstrated. The probe is shown to havesimilar efficiency to NaI(Tl) detectors used for holdup measurements.
