Radiation studies of silicon-microstrip detectors for use in ATLAS and SCT

Silicon detectors designed for use in ATLAS at CERN's Large Hadron Collider, Geneva, Switzerland, are shown to operate satisfactorily after irradiation with 3/spl times/10/sup 14/ (24 GeV/c protons)/cm/sup 2/. No breakdown effects are seen with the detectors biased up to 500 V.
