Paper Abstract

Germanium strip detectors combine high quality spectral resolution with two-dimensional positioning of gamma-ray interactions. Readout is accomplished using crossed electrodes on opposite faces of a planar germanium detector. Potential astrophysics applications include focal plane detectors for coded-aperture or grazing incidence x-ray mirror imagers, and as detection elements of a high resolution Compton telescope. We report on test results of two germanium strips detectors, one with 2 mm position resolution, the other with 9 mm. We discuss general device performance in terms of energy and position resolution, crosstalk effects, potential applications, and a demonstration of imaging properties.
