A new method to suppress high-order harmonics for synchrotron radiation soft x-ray beamline
摘要：
提出了一种在软X射线波段抑制变线距平面光栅单色器高次谐波的简便可行的方法。相关的计算和实验表明，通过改变出射臂长参数，略微减小夹角，可以显著提高光纯度。该方法适用于北京同步辐射装置（BSRF）4B7 B光束线探测器定标实验。
英文摘要：
A feasible and convenient method has been proposed to suppress higher-harmonics for varied-line-spacing (VLS) plane grating monochromator in soft x-ray region. Related calculations and experiments demonstrate that decreasing the included angle slightly by changing the parameter of exit arm length can significantly improve light purity. This method is suitable and has been used for experiments of detector calibration in beamline 4B7B at Beijing Synchrotron Radiation Facility (BSRF).
