Gamma ray spectrometers are an important
element of nuclear and elementary particle physics experiments. However,
the performance of the detection systems used in these experiments is often
limited by the properties of presently available detectors.
This project will investigate a new design for cadmium zinc telluride
(CZT) detectors that promises to provide high energy resolution and high
detection efficiency at room temperature in a cost-effective manner.
Phase
I demonstrated the feasibility of implementing the new detector design on large
volume CZT detectors. Simulation
studies as well as experimental evaluation of the new CZT detector design was
carried out. During Phase II, the
preparation and properties of large CZT detectors will be evaluated,
particularly from the view-point of use in nuclear physics experiments.
Simulation studies of the new detector also will be conducted.
Commercial
Applications and Other Benefits as
described by awardee: Over
and above its scientific use in nuclear, high energy, and space physics
experiments, the new scintillator should be commercially applicable to medical
imaging, NDE, geological exploration, industrial CT imaging, nuclear
non-proliferation, and materials analysis.
