This paper introduced a new technique about calibration of a single-photon counting X-ray CCD. The principle of the CCD was described. In the calibration experiment, several standard X-ray sources were adopted to radiate forward the CCD detector and the counts occured. When the CCD was in a state of single-photon counting, the X-ray intensity was obtained with integral. After deducting the background, the photon energy of 6.453 eV that produced one count was calibrated. Based on this result, the detection efficiency of the CCD was calculated. The detection efficiency changed with photon energies in the range of 5.3~30 keV. The efficiency decreased with the increase of the photon energy.
