摘要

Two kinds of photodiodes have been investigated for the ATLAS SCT readout. We present in this paper the results of irradiating bulk and epitaxial Si PIN diodes with 1MeV-equivalent neutrons and 24GeV protons. The devices were biased during some of the tests. They were exposed to a fluence of around 2.5 × 1014 n cm−2 followed by a fluence of approximately 2.5×1014 p cm−2.
