Arrays of position sensitive virtual Frisch-grid detectors (Conference Presentation)

Paper Abstract

We present new results from testing a small array of position-sensitive virtual Frisch-grid gamma-ray detectors. Such arrays provide high-detection efficiency, excellent energy and position resolution. They can be used in compact hand-held instruments or in large-area gamma ray imaging cameras. The high granularity position sensing enables these detectors to correct the response non-uniformity caused by crystal defects. This important feature allows one to achieve high detection performance while using standard-grade (unselected) CZT crystals, which is expected to reduce the overall cost of field deployable high-resolution CZT gamma ray detection instruments. Here, we report the results of testing several array prototypes with configurations designed for different applications.
