Paper Abstract

We present results of detailed characterization of the spatial properties of large area crossed strip CZT detectors now under development at CASS/UCSD for use in coded aperture astrophysical hard X-ray instrumentation. We address the volumetric uniformity of spectral response for these detectors as determined by charge sharing and loss, diffusion, and electron trapping. Results are presented for our prototype detector having 500 μm pitch and collecting area 32×32 mm2; however, we also explore these characteristics as they effect performance of larger and smaller pitch detectors of similar design.
