From: Repeated radiation damage and thermal annealing of avalanche photodiodes
Post-annealing dark count rates. DM1 is thermally annealed after each incremental irradiation, whereas DM2 is annealed only if the post-irradiated dark count rate exceeds 2Â kcps on at least two detectors. Comparing the post-annealed dark count rates at \(3.35\times 10^{9}\)Â p/cm2 and \(4\times 10^{9}\)Â p/cm2 cumulative fluences, DM2 evidently achieves lower values across most detectors compared to DM1
