Laboratory and radiation performance testing results for the e2v model 212 CCD

摘要

The e2v CCD212 was designed and developed explicitly to support very high accuracy astrometric observations in moderate radiation environments in space. One of the major new innovations in the detector is the use of "charge canals", I.e. regions of raised potential walls rather than notches or channels, in order to mitigate bulk damage effects without the CTI discontinuities associated with spilling over the notch capacity. We report on both pre- and post-radiation performance test results for this detector.
