Gamma-ray spectroscopy with real-time readout is applied in portable and fixed (continuous) quantitative assays of in-situ special nuclear materials (SNM). Hold-up, in-process inventory, stored inventory, and dynamic materials are several categories of SNM for which in-situ measurements are required. Conventional room-temperature gamma-ray detectors serve in a limited number of these applications, but these detectors have a low gamma energy resolution that limits their sensitivities. It is necessary to develope room temperature detectors with improved sensitivity, and the promising approach is an elegant new detector design that benefits from the recent advances in solid-state materials technology for the production of large, good-quality crystals of CdZnTe. The detector operates with a miniature, modular, multi-channel analyzer. Characteristics of this detector are briefly discussed in this paper.
