Device Simulation of a Unipolar Gamma-Ray Detector
The pulse height spectra from a new kind of unipolar gamma-ray detectors were predicted using a new three-dimensional simulation program developed at Sandia National Laboratories. The detectors were fabricated...

On the Active Volume of Cadmium Zinc Telluride Gamma-Ray Spectrometers
In this paper we develop quantitative models to predict the active volume of cadmium zinc telluride (CZT) detectors operated as gamma-ray pulse height spectrometers. Three cases are considered: a conventional ...

Gamma-ray imaging and spectroscopy system using room-temperature semiconductor detector elements
We report on the design, construction, and testing of a gamma-ray imaging system with spectroscopic capabilities. The imaging system consists of an orthogonal strip detector made from either HgI2 or CdZnTe crysta...
