Abstract

Large area, high spatial resolution CdZnTe pixel detectors are being developed for hard X-ray astronomy. We have designed and fabricated custom readout chips and bump-bond these to pixelated CdZnTe crystals using indium bump bonding technology. The resulting detectors have 16 x 16 pixels with 300 micron pitch, enabling low noise operation and permitting detailed imaging. These devices are ideally suited for the focal plane of future high-resolution hard x-ray focusing telescopes now being considered, such as the HXT on Constellation-X. An initial demonstration using the sparse read-out capabilities of these detectors is presented.
