Xl. Sun et al., MEASUREMENT OF PROTON RADIATION-DAMAGE TO SI AVALANCHE PHOTODIODES, I.E.E.E. transactions on electron devices, 44(12), 1997, pp. 2160-2166
The effects of proton radiation damage on EG&G C30902S Si avalanche ph
otodiodes (APD's) were measured, The APD bulk leakage current increase
d at 0.29 fA/rad, or about 1800 dark photoelectrons per rad(Si) at -10
degrees C under 16.2 MeV protons. There were little changes in the br
eakdown voltage, with the radiation doses up to 30 krad(Si). The incre
ase in the total dark currents below the breakdown voltage was insigni
ficant until 3 krad(Si).
