A monochromator stabilization system with a semi-automatic tuning procedure has been developed. The system comprises an X-ray beam position/intensity monitor, a control electronics unit, a computer program that operates on a personal computer or workstation, a piezo translator attached to the first crystal of a double crystal monochromator, and a phase-sensitive detector as an optional component. The system suppressed the fluctuations of the photon beam intensity and the beam position by {approx}0.1% and {approx}1 {mu}m, respectively, at the sample locations in the beamlines of SPring-8 with a frequency of less than 10 Hz. The system with the phase-sensitive detector holds the peak of the rocking curve of the double crystal monochromator, which is effective in reducing the time required to perform the energy scan measurement.
