Abstract :
The charge collection efficiency of the n+n silicon microstrip detectors for the ATLAS forward tracking has been evaluated for detectors irradiated with 24 GeV/c protons. The charge collection efficiency is found to be 99±1% after a fluence of 2×1014 protons/cm2 and 81±2% after 4×1014 protons/cm2. Furthermore, the charge collection efficiency of the detector irradiated with the lower dose does not show any dependence on the isothermal annealing up to 52 days at 20°C, as it remains constant through the whole annealing cycle.
