Table 1 Nine groups of tested samples and their corresponding nominal radiation fluences, equivalent to in-orbit exposures over 0.6, 6, 12 and 24 months with protons at 100 MeV. Each APD in group 5 was biased during irradiation at 20 V above its breakdown voltage. Group 9 was not irradiated, and kept as a control
