Abstract: We report on the laboratory testing of two candidate CCDs for space astrometry missions: the STA700 and e2v CCD43 models. We measured noise, dark current and charge transfer inefficiency for both CCDs after high energy proton irradiation at a level equivalent to five years on-orbit for HST, and assessed how effective the radiation damage mitigation capabilities were for each detector. Neither detector fully meets AMEX-level requirements for high-speed, low-noise, radiation hard performance. We discuss future work that should result in development of CCDs that will meet requirements for space astrometry.
