Abstract :
Cadmium Zinc Telluride (CZT) and Cadmium Telluride (CdTe) detectors with 200 μm pixellated electrodes were tested with the aim to determine material properties and electrical parameters for hybrid pixel detector (HPD) systems. A 32 channel discrete analogue preamplifier platform was designed and manufactured in which radiation tests were performed on packaged detectors. Although simple in concept, numerous obstacles were encountered as a result of the bump bonding process. This paper provides an overview of HPD development at the Monash Centre for Synchrotron Science, details the tests performed on the current prototype detectors and illustrates the general methodologies used on the development pathway.
