摘要
Previous work has shown that hybrid semiconductor detector arrays similar to those used in infrared focal-plane arrays are very attractive for use in nuclear medicine and other gamma-ray imaging applications. In this paper, we describe the development of a 64 x 64 readout multiplexer specifically for use in gamma-ray imaging; we also describe the construction of 64 x 64 CdZnTe hybrid detector arrays using the new readout. The readout and detector array are both about one inch square (2.5 cm x 2.5 cm) and have 380 mu m pixel pitch. Some initial assembly problems have been resolved by stabilizing the hybrids with epoxy. Preliminary testing results are presented that verify that the 64 x 64 CdZnTe arrays perform as excellent imaging spectrometers.
