Description
Modern avalanche photodiodes (APDs) with high gain are excellent device candidates for the light readout from detectors used for the high energy physics experiments. We report the results of the APDs radiation hardness study. Properties of APDs manufactured by Zecotek, Ketek and Hamamatsu companies are studied in terms of internal defects accumulation. Test setups for offline and online APD irradiation measurements are described. Simplified models estimating contribution of various noise components are discussed in comparison with data achieved by static and dynamic characteristics analysis and Fourier analysis. The results of the APDs investigations after irradiation using secondary neutrons from the cyclotron facility U120M at the Nuclear Physics Institute of ASCR in Řež are presented. The results of the investigations can be used for the design of the Projectile Spectator Detector (PSD) for the CBM experiment at the future FAIR facility, the Forward Wall Detector (FWD) for the Baryonic Matter Spectrometer (BM@N) and the Multi Purpose Detector (MPD) at the future NICA facility.
