Study of the PIN detectors radiation tolerance
PIN detectors have been extensively used to detect charged particles and X-ray.The new type PIN detectors were irradiated by different energy protons,and their irradiation tolerance was investigated.Relative charge collection efficiency,energy spectrometer and relative energy resolution were also measured.With the increasing of irradiation dose,charge collection efficiency decreased and relative energy resolution grown.The results suggested that the irradiation tolerance in the PIN detector depended on the range of the protons in the detector.The maximum tolerance irradiation doses of the detector for the impacts of 3.5 and 7.2 MeV protons were 3 × 1010 p/cm2 and 7.2 × 109 p/cm2,respectively.
