Future space applications of compound semiconductor X-ray detectors

Detectors based on compound semiconductors have now reached a level of matu rity, where they can be considered for use in a variety of space-based appl ications involving X-ray imaging optics. The possible range of space applic ations is reviewed and the key future requirements of these detectors are d iscussed. These X-ray detectors will play a major role in future astrophysi cs and planetary missions. Recent results on the agency's X-ray detector re search and development program into such materials as TIBr, epitaxial GaAs and CdZnTe are presented. (C) 2001 Elsevier Science B.V.
