Paper Abstract

We report on the measurement results for two candidate astrometric CCD designs, the STA700 and the e2v CCD43. Both of these CCDs have been considered as design baseline CCDs for use in a high-precision astrometric instrument in space, similar to the one proposed for the FAME, DIVA, or AMEX missions. We have exposed one sample CCD of each design to a fluence of 5 x 109 p+ cm-2 (@ 63.3 MeV), then measured the relevant readout noise, dark current, charge injection noise, and CTI performance. We compare the two CCDs and assess how well each mitigates radiation damage.
