Paper Abstract

Orthogonal transfer array CCDs were originally developed by the University of Hawaii and MIT Lincoln Laboratory for use in the focal planes of the ground-based Panoramic Survey Telescope and Rapid Response System (Pan-STARRS). These devices have relatively large area (5x5 cm) and a novel, multiple-output readout architecture that makes them attractive for certain applications in spaced-base X-ray astronomy. We have therefore conducted a series of tests to determine their sensitivity to proton radiation encountered on-orbit. We report effects of typical on-orbit proton exposure on charge transfer efficiency, dark current, noise and spectral resolution as a function of device operating temperature and readout parameters.
