已经开发了具有半自动调谐程序的单色器稳定系统。该系统包括X射线束位置/强度监视器、控制电子单元、在个人计算机或工作站上运行的计算机程序、连接到双晶体单色器的第一晶体的压电转换器以及作为可选组件的相敏检测器。该系统在SPring-8光束线的样品位置处，以小于10 Hz的频率，将光子束强度和光束位置的波动分别抑制了0.1%和0.1 μm。具有相敏检测器的系统保持双晶单色器的摇摆曲线的峰值，这在减少执行能量扫描测量所需的时间方面是有效的。
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 ∼0.1% and ∼1 μm, 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.
