Scientific paper

Charge coupled device (CCD) image sensors are rapidly gaining in importance as candidate focal plane detectors for X-ray astronomy. Methods of event selection and recognition are described, which allow excellent X-ray energy resolution (e.g. 133 eV FWHM at 4.95 keV) to be attained. The recognition and discrimination of charged particle background events is also shown to be efficient (up to 99.9%). Changes in CCD design to allow optimisation for X-ray imaging spectroscopy are discussed, and it is demonstrated that CCDs may offer, simultaneously, high spatial resolution, good energy resolution, high detection efficiency and good background rejection.
