Paper Abstract

Recently developed CdTe detectors with a Schottky anode contact are well suited for (gamma) -ray imaging applications in astrophysics and nuclear medicine. Since the response of the detectors to (gamma) -rays is homogeneous throughout their volume the detectors can be oriented to let the radiation enter perpendicular to the electric field. Thus, large area arrays with 10 mm thickness can be assembled. The leakage current and capacitance of the detectors is sufficiently low to connect more than a hundred together in a row-column read out reducing the number of electronic channels.
