Abstract

We present the initial results of the first germanium strip detector array for the imaging and high-resolution spectroscopy of gamma-ray sources. The array consists of four detectors, 5 × 5 × 1 cm each, with 25 strips on each side. The detectors are daisy chained to hybrid preamplifiers to reduce the number of channels of electronics. Good spectroscopy and imaging are achieved. We also present results from the development of an amorphous germanium contact technology as an alternative to the lithium contact technology. A prototype 25 × 25 strip detector was manufactured with this new technology and demonstrates good spectroscopy and imaging
