Abstract
Results on the radiation hardness of photodiodes to fast neutrons are prese nted. Four photodiodes (three avalanche photodiodes from two manufacturers, and one PIN photodiode) were exposed to neutrons from a Cf-252 source at O ak Ridge National Laboratory. The effects of this radiation on many paramet ers such as gain, intrinsic dark current, quantum efficiency, noise, capaci tance: and voltage and temperature coefficients of the gain for these devic es for fluences up to similar to 2x10(13) neutrons/cm(2) are shown and disc ussed. While degradation of APDs occurred during neutron irradiation, they remained photosensitive devices with gain. (C) 2000 Elsevier Science B.V. A ll rights reserved.
