A New Generation of Red-Sensitive CCDs

Abstract: High-resistivity charge-coupled devices are currently being developed at Lawrence Berkeley Laboratory. The CCDs are fully depleted by an external bias voltage, and are 200-300 micrometers thick. We review basic CCD function and present high-voltage development results for visible and infrared quantum efficiency, radiation tolerance, point spread function, and charge transfer efficiency. These CCDs will be used for space and ground-based telescopes such as SNAP, DES, and LSST.
