Abstract
AC-coupled silicon strip detectors were exposed to neutron fluences of 5·1013n/cm2 and to Co60 photon doses of 2.8 Mrad. No change in the value of the coupling capacitors was observed. Polysilicon resistor values increased by 15% and saturated after 200 krad photon dose. They were stable under neutron irradiation. Thee interstrip punchthrough threshold voltage increased from 4 to 13 V under photon irradiation. The accumulation of fixed charges in SiO2 was measured using MOS capacitors and the photon-induced surface current generation velocity was determined with gated diodes.
