摘要

Irradiation effects of proton and gamma-ray on a CVD diamond detector were studied on Beijing Tandem accelerator and ⁶⁰Co source. The decrease of the detector's signal current was less than 3.5% after irradiated by 10¹³ cm^-2, 9 MeV continuous protons. Dark current didn't change obviously after the proton irradiation. The calculated radiation damage coefficient is 1.3 × 10¹⁶ μm^-1·cm², which is much higher than that of Si PIN detectors. The signal current increased a little after irradiated by 10.32 C/kg and 1.25 MeV γ-ray, as the electrons excited by γ-ray can deduce traps in diamond. And the increase is less than 0.7%. Diamond detector has high radiation hardness and can be used in high radiation detection.
