Sensors for the Hubble Space Telescope wide field and planetary cameras (1 and 2)The technology of the wide field planetary camera (WFPC-2) CCD technology is examined with reference to the WFPC-1 experience. Strategies are presented for elimination of quantum efficiency (QE) hysteresis and implementation of maintenance-free QE stability, improved far-UV performance, on-orbit photometric calibrations, refinements in CCD electronics, and anticipated CCD particle radiation effects. Absorption depth vs. wavelength in silicon and a cross section of the CCD membrane are shown.
