Measurements of Parameters on Large Area PIN Detectors

Key words: 
• PIN detector

Abstract: Ф60 mm silicon PIN detector is a large area and high sensitive one which has been developed in near years. Using the type CГC-67 γ accelerator, the parameters of PIN detectors such as time response, linear current and relative sensitivity are measured. The experiment results are compared with the theory calculation. The PIN detector can reach high γefficiency of up to 10^-14-10^-16 C·cm2, the rise time is about 10 ns and the FWHM of the time pulse is about 35 ns. The γ efficiency of the PIN detector may provide the sensitive range between 10^-14-10^-16 C·cm^2 that scintillator ＋ photo tubes detecting system and scintillator ＋ photomul tiplier tubes detecting system is not developed.
