弧矢(Sagittal)聚焦双晶单色器设计

Design of a sagittally focusing double-crystal monochromator in synchrotron radiation

介绍了弧矢聚焦双晶单色器系统性能要求 ,详细分析了满足系统性能要求的光学设计、机械设计和控制系统设计方案。具体介绍了单色化和压弯聚焦等光学设计 ,Bragg角的转动和固定高差的移动等关键部件的机械设计 ,以及以直圆柔性铰链为基础的投角、滚角。

This article briefly remarks the optical design, structure design and control design of a sagittally focusing double-crystal monochromator, and introduces the structure design of the sticking point (homochromatism, focusing and the wheeling of the Bragg) and the adjustment frame of yaw, pitch and roll in the monochromator based on the right circular flexure hinge.
