“…Damage distributions were first calculated analytically by Marshall et al in 1990 with good agreement obtained for dark current distributions produced by 12 MeV protons in Si charge injection devices. At 63 MeV the data indicated less variance in the measured distribution than in the damage energy calculation, a result also found by Hopkinson et al at 100 MeV in Si charge coupled devices (CCDs).…”

Abstract-This paper presents a combined Monte Carlo and analytic approach to the calculation of the pixel-to-pixel distribution of proton-induced damage in a HgCdTe sensor array and compares the results to measured dark current distributions after damage by 63 MeV protons. The moments of the Coulombic, nuclear elastic and nuclear inelastic damage distributions were extracted from Monte Carlo simulations and combined to form a damage distribution using the analytic techniques first described in [I]. The calculations show that the high energy recoils from the nuclear inelastic reactions (calculated using the Monte Carlo code MCNPX [2]) produce a pronounced skewing of the damage energy distribution. While the nuclear elastic component (also calculated using the MCNPX) contributes only a small fraction of the total nonionizing damage energy, its inclusion in the shape of the damage across the array is significant. The Coulombic contribution was calculated using MRED 13-51, a Geant4 [4,6] application. The comparison with the dark current distribution strongly suggests that mechanisms which are not linearly correlated with nonionizing damage produced according to collision kinematics are responsible for the observed dark current increases. This has important implications for the process of predicting the on-orbit dark current response of the HgCdTe sensor array.

“…The degradations of charge transfer inefficiency (CTI) and dark current induced by 10 and 60 MeV proton irradiation have also been studied [3]. The mean degradation of the dark current and the dark signal non-uniformity induced by proton irradiation from 17 MeV to 100 MeV have been analyzed [5]. The random telegraph signal behavior induced by 1.5, 10, and 46 MeV protons irradiations have been presented previously in [6].…”

“…Proton displacement damage effects on CCDs have also been extensively investigated. [6][7][8][9][10] Histograms of dark current in p-buried channel CCDs irradiated by 10 MeV protons are available in the literature. 6 Dark signal spikes in EEV three phase CCDs irradiated by 40 MeV protons are investigated.…”

“…7 Mean degradation of dark current and DSNU induced by proton irradiation from 17 to 100 MeV are analyzed. 10 On the contrary, fewer studies focus on neutron displacement damage effects on CCDs, especially in the case of reactor neutrons. It is important to note that neutron irradiation brings only displacement damage because neutral particles induce negligible ionization.…”

The experiments of reactor neutron irradiation which induce dark signal increase in COTS array CCDs are presented. The flux of the reactor neutron beams was about 1.33 × 108 n/cm2s. The three samples were exposed to 1MeV neutron-equivalent fluences of 1 × 1011, 5 × 1011, and 1 × 1012 n/cm2, respectively. The mean dark signal (KD), dark signal non-uniformity (DSNU), and dark signal spikes (hot pixels) versus neutron fluence are investigated. The degradation mechanisms of the dark signal in CCDs are analyzed. The mean dark signal increase due to neutron displacement damage appears to be proportional to displacement damage dose. The dark images from the CCDs irradiated by neutrons are presented to investigate the generation of dark signal spike. The 1D and 2D figures which show the output signal voltage of pixels in dark images irradiated by different neutron beam fluences, are presented to compare the degradation of KD, DSNU, and dark signal spike.
