This paper introduces energy response and detection efficiency calibration of single-photon counting CCD by X-ray source. In the calibration experiment, several standard X-ray sources are adopted to radiate forward the CCD detector and the counts occur. Energy response curve of CCD is close to linear, but the curve slope of different CCD is evidently different. The MATLAB program for studying the detection efficiency and the split pixel event is set up. The detection efficiency of CCD changes with photon energy in the range of 3.1-24.9 keV, and the detection efficiency obtained from the calibration experiment is in agreement with absorption efficiency that is offered by XOP software.
