Found! A CCD that meets space astrometry requirements

We report on the measurement results for the STA model 1046 CCD, designed to support requirements for USNO's proposed Astrometric Mapping Explorer (AMEX) space astrometry mission. The STA1046 is found to meet AMEX requirements for operating speed, read noise, charge transfer inefficiency (CTI) and dark current after exposure to a high-energy proton fluence of 5 x 109 p+ cm-2 (@63.3 MeV). The lab measurements provide the basis for developing a validated performance model of the STA1046 which we use, along with USNO's Radiation Effects Simulation (RES), to predict on-orbit centroiding performance of an STA1046-based instrument.
