DCR of APDs biased during irradiation. The highlighted portion represents the period of irradiation. While the irradiation is on, the DCR of each APD increases until saturation in the passive quenching circuit, after which saturation causes an apparent (not real) decrease in the DCRs [31]. After irradiation ceased, actual DCRs slightly improved due to spontaneous annealing, leading to an apparent DCR rise in the over-saturated samples.
