The charge coupled device (CCD) is useful as an imaging detector in the X-ray waveband, and when used to detected single photon events can simultaneously provide spatial imaging and energy resolution. This capability is important in the field of X-ra

The X-ray detection efficiency of charge coupled devices (CCDs) is dependent on the thickness of the active depletion layer in the silicon, typically less than 40 μm and limited by the purity of available epitaxial substrates. For X-ray imaging, the
