Figure 2
Flat-field response obtained by dividing a post-irradiation flat-field by that of a pre-irradiation flat-field, without trimming. Each data point represents a pixel; however, analysis was constrained to the four highest-dose regions of Fig. 1[link]. A shaded 2σ variation band, representing the count-rate dispersion of un-irradiated pixels, has been used in conjunction with an indicative trend line to approximate the dose required to induce departure from nominal sensor behaviour. Irradiation clearly increases pixel sensitivity.
