Results on double-sided d.c.-coupled silicon strip detectors irradiated with photons up to 1 Mrad
1996
We irradiated with photons from a60Co source a double-sided d.c.-coupled silicon strip detector and several test structures fabricated at CSEM. We measured the leakage currents and the interstrip and backside capacitances. Up to a maximum dose of 1 Mrad, the current densities are always below 350 nA/cm2, mostly due to thermally generated surface currents. The interstrip capacitances increase at most 17% with respect to not irradiated detectors, while the backside capacitances do not change.
