Study of high temperature semiconductor radiation detector

We describe the results of our study of response/performance of CdTe Schottky diode and CZT diode detectors in the energy region 10-1330 keV and Si--PIN detector in the energy range 5--60 keV using different radioactive sources like Fe--55 , Am--241 , Cd--109 and CO--57. We have also studied performance and linearity of the charge sensitive pre-amplifiers, main amplifiers of respective detector system and multichannel analyser (MCA 8000A) from the electronics part of the system. Effort has been made to study any change/degradation in the performance of these detectors over last two years and we have not detected any degradation.
