CHARACTERIZATION AND PERFORMANCE EVALUATION OF AN HPXe DETECTOR FOR NUCLEAR EXPLOSION MONITORING APPLICATIONS
Expanding missions in nuclear explosion monitoring (NEM) and nuclear security have highlighted the need for high-resolution ambient-temperature gamma detectors that can provide radionuclide-specific monitoring under demanding field conditions. Recent improvements in high-pressure xenon (HPXe) detectors indicate that this technology has potential to provide rugged, large volume ambient temperatu...
متن کاملDesign and Modeling of a Compton-suppressed Phoswich Detector for Radioxenon Monitoring
By measuring the concentration of four xenon radioisotopes in the atmosphere, the International Monitoring System (IMS) can verify nuclear weapons tests around the world. To measure ultra-low concentrations of radioxenons, many detection systems, such as the Automated Radioxenon Sampler and Analyzer (ARSA) and the Swedish Automatic Unit for Noble gas Acquisition (SAUNA), have been developed and...
متن کاملNuclear Explosion Monitoring Research and Development Roadmaps
In the past ten years, significant progress has been made in nuclear explosion monitoring (NEM) through research and development (R&D) with regard to detection, location and identification, however substantial improvements are yet possible. Today, there is increasing interest in both current and planned NEM R&D technology particularly in light of its relevance to the Comprehensive Nuclear-Test-...
متن کاملPerformance Evaluation of a New CZT Detector for Nuclear Medicine: SOLSTICE
Solstice is a new concept of gamma camera designed to use the better energy resolution typically available in solid-state detectors. To that purpose, an array of 88 Cadmium Zinc Telluride (CdZnTe or CZT) crystals was characterized for gamma ray detection performance. The bias voltage was applied to the single electrode cathode side of the crystal (radiation side). The anode side of the individu...
متن کاملDetector and Telescope Development for ProtoEXIST and Fine Beam Measurements of Spectral Response of CZT Detectors
We outline our plan to develop ProtoEXIST, a balloon-borne prototype experiment for the Energetic X-ray Imaging Survey Telescope (EXIST) for the Black Hole Finder Probe. EXIST will consist of multiple wide-field hard X-ray coded-aperture telescopes. The current design of the EXIST mission employs two types of telescope systems: high energy telescopes (HETs) using CZT detectors, and low energy t...
