Abstract

We report the status of ongoing investigations into Cadmium Zinc Telluride (CZT) strip detectors for application in hard x-ray astronomy. We have instrumented a nine strip by nine strip region of a two sided strip detector made in our detector fabrication facility. In order to measure the position resolution of our detectors, we have implemented acollimated beam that concentrates radiation to a spot size less than 50 mu m We have placed a 30 mu m upper limit on the width of the pointspread function for this system. We have also performed charge collection studies as a function of incident photon energy and bias voltage with a single sided, 100 mu m pitch CZT strip detector wire bonded to an SVX ASIC charge amplifier. The detectors exhibited excellent strip uniformity in terms of photon count rate and spectroscopic information.
