In recent years, the silicon charge coupled device (CCD) has found use in many applications in space science providing imaging solutions to a variety of instrument needs. Whilst the majority of imaging applications using CCDs are in the visible region, the ability of silicon to perform efficient detection of X-rays in the 0.1 keV to 10 keV band enables their use in, for example, X-ray astronomy. Since the early 1990s several instruments have been flown using X-ray-optimised CCDs as both non-imaging and imaging detectors at the focal planes of X-ray telescopes. This chapter reviews the use of the silicon CCD for direct detection in the X-ray region and describes some successful applications, together with radiation damage effects when used in the space environment.
