Scientific paper

The paper presents the capabilities of a charge-coupled device (CCD) as an imaging instrument with energy resolution for future cosmic X-ray telescopes. CCD will simultaneously fulfill requirements for high angular resolution, high quantum efficiency, and moderate spectral resolution. Verification and detection of single X-ray photons was verified, and established many requirements for application to the advanced X-ray Astronomy Facility. These include cooling of the device, a maximum readout of 0.3 sec, and a minimum thickness of 50 microns to detect 7 keV X-rays and to provide a clear discriminant against cosmic rays and charged particles. An algorithm was used to recognize event existence and then sum charges from several adjacent pixels to obtain the position centroid location and to optimize the energy resolution.
