Charge transfer and dark current effects are compared for regions of a large area 4500 × 1966 pixel CCD irradiated with 7.4 MeV protons at −130°C and at room temperature. Post-annealing measurements were also performed. Although there are differe

Cobalt60, 60 MeV proton and heavy ion tests have been performed on InGaAs and amorphous silicon microbolometer arrays with CMOS readout circuits. The readout circuits showed latch-up at threshold LETs~14 MeV/mg/cm2, but the total dose and displacemen

A STAR1000 CMOS active pixel sensor was irradiated with alpha particles at -130deg C and dark current measurements were made at temperatures up to 25degC. Approximately 90% of dark current spikes were seen to anneal near room temperature. This implie

The performance of a large area 4500times1966 pixel CCD was measured after alpha particle irradiation at -135degC. Trap concentrations (as measured by deferred charge and first pixel response) were a factor ~1.3 higher than after annealing to room te

2011 12th European Conference on Radiation and Its Effects on Components and Systems.
Cobalt60, heavy ion and proton irradiations of the LUPA4000 2048×2048 pixel CMOS image sensor were performed to assess the performance for ESA's proposed Solar Orbiter mission. Performance is acceptable up to at least 20 krad(Si).

A new automated method able to detect multilevel random telegraph signals (RTS) in pixel arrays and to extract their main characteristics is presented. The proposed method is applied to several proton irradiated pixel arrays manufactured using a 0.18

Random telegraph dark signal fluctuations have been studied in two types of CCD and two types of CMOS active pixel sensor after proton irradiation at 1.5, 10 and 60 MeV. Time constants and activation energies were very similar, indicating a similar d
