Understanding the effects of high energy proton radiation is essential in planning for the next generation of X-ray space telescopes. We report on the results of an experiment in which an X-ray hybrid CMOS detector was incrementally irradiated with 8 MeV protons up to a total absorbed dose of approximately 3 krad(Si) (4.5 x 109 protons/cm2). The effect of the damage caused by the high energy protons is then analyzed in the context of several detector characteristics, including read noise, dark current, and energy resolution.
