The article presents results of investigation of interaction of the structu
res based on GaAs compensated by interaction of the deep centers with ioniz
ing radiation of a wide spectral range. The structures are able to record s
ingle quantum of electromagnetic radiation with energy E greater than or eq
ual to 5 keV, have high-speed response and radiation resistance and can be
used for the development of high-efficiency multi-element detectors for mod
ern diagnostic systems. (C) 2000 Elsevier Science B.V. All rights reserved.
