Performance characteristics of pixelated CZT crystals used on the GammaTracker project
2011
GammaTracker is a handheld radioisotope identification device in development at Pacific Northwest National
Laboratory that uses eighteen pixelated Cadmium-Zinc Telluride (CZT) crystals to provide energy resolution
approaching that of high-purity germanium without the need for cryogenic cooling. Additionally, these crystals can be
used to provide directional and imaging capabilities that cannot be found in other handheld detectors. A significant
number of CZT crystals have been procured during the development of the GammaTracker system; the majority of these
were procured with the same set of specifications. Each of these detectors has been characterized in terms of key
parameters, including current-voltage response and pixel-by-pixel energy resolution. The results of this testing indicate
that the overall quality of CZT crystals is improving over time.
