本文提出了一种用于异常衍射数据采集的X射线入射能量的标定和稳定方法，并成功地应用于北京同步辐射装置单晶衍射光束线1W2B上。该方法采用反馈回路控制双晶单色器的运动，使入射X射线能量在吸收边拐点处保持在0.2eV范围内。
A method to calibrate and stabilize the incident X-ray energy for anomalous diffraction data collection is provided and has been successfully used at the single-crystal diffraction beamline 1W2B at the Beijing Synchrotron Radiation Facilities. Employing a feedback loop to control the movement of the double-crystal monochromator, this new method enables the incident X-ray energy to be kept within a 0.2 eV range at the inflection point of the absorption edge.
