简要介绍了弧矢聚焦双晶单色器的作用及基本原理,描述了离线测量弧矢聚焦双晶单色器出射光斑位置的方法。此方法为弧矢聚焦双晶单色器出射光束位置的快速装调提供了有效的措施。
This paper briefly introduces the role and basic principle of sagittal focusing twin-crystal monochromator, and describes the method of off-line measuring the spot position of sagittal focusing monochromator. This method provides an effective measure for the quick setting of the position of the outgoing beam of the sagittal focusing twin-crystal monochromator.
