INVESTIGATION OF AVALANCHE PHOTODIODES RADIATION HARDNESS FOR BARYONIC MATTER STUDIES

Modern avalanche photodiodes (APDs) with high gain are good device candidates for light readout from detectors applied in relativistic heavy-ion collision experiments. The results of the investigations of the APDs properties from Zecotek, Ketek, and Hamamatsu manufacturers after irradiation using secondary neutrons from U120M cyclotron facility at NPI of ASCR in Ä ReÄ z are presented. The results of the investigations can be used for the design of the detectors for the experiments at NICA and FAIR.
