Description

The automatic gain control system (AGC) is designed to continuously monitor and automatically control the gain of the phoswich detectors of the Hard X-ray Modulation Telescope (HXMT). It consists of a 241Am radioactive source distributed within a plastic scintillator (BC408) viewed by Multi-Pixel Photon Counter (MPPC). To verify the feasibility of application in space experiments, four MPPCs (S10362-33-050C) from Hamamatsu were irradiated using a beam of 23MeV protons with flux 1.0×108pcm-2, 2.0×108pcm-2, 4.0×108pcm-2 and 1.0×1010pcm-2. The leakage current of irradiated MPPC samples is found to increase linearly with total dose due to radiation damage. The device has completely lost its photon-counting capability when irradiated up to 13.6Gy. The pulse-height resolution has deteriorated hardly after irradiation and couldn't work with more than 450Gy, where the measured sample has been illuminated with a few hundred photons by the 241Am radioactive source.
