Popis: Detectors with integrated amplification and memory (DEPMOS counters) were irradiated by 10 MeV protons with doses up to 8 kGy. While the device remains fully operational, radiation damage is found to reduce the period τ for thermal filling-up of the internal storage gate, i.e. the period required for reset, and to shift the transmission characteristics of the MOS transistor component. The exponential temperature dependence of τ enables extensions to several min (s) before (after) irradiation by cooling to 220 K.
