Deep-depletion CCDs for X-ray astronomy.
Abstract
The successful use of deep-depletion silicon CCDs as single photon X-ray detectors is described. At an X-ray energy of 5.9 keV, a quantum efficiency of 76 percent for a 56 micron deep, 4000 ohm-cm RCA CCD has been measured (three times that of a conventional CCD). The high X-ray quantum efficiency, high spatial resolution, and ability to reject charged particle background make the deep-depletion CCD one of the strongest contenders for focal plane instrumentation on AXAF, the Advance X-ray Astrophysics Facility.
