Some recent results of the silicon detector radiation damage study by the RD2 collaboration

Abstract Recent results by the RD2 Collaboration of a study of radiation damage of silicon detectors for the ATLAS detector at LHC are presented. The detectors have been irradiated by neutrons with fluences of up to 1.5 × 10 14 neutrons/cm 2 . The electric field in the detectors before and after type inversion, the depletion voltage and the dark current were studied.
