[16.21] Thick CZT Detectors for Space Borne X-Ray Astronomy

Cadmium Zinc Telluride (CZT) has emerged as the detector material of choice for X-ray imaging spectroscopy in the 10 keV to 600 keV energy range. We contacted 0.5 mm thick substrates from the companies IMARAD, eV-Products, and Bicron with Gold and Platinum. In this contribution, we present a complete characterization of detectors with pixellated anodes (2.5 mm pitch) and monolithic cathodes. In addition, we discuss how to obtain the best estimate of the interaction location (3-D) and the photon energy for all photons striking the detector, including photons that hit the detector in-between adjacent anode pixels.
