光束线反射镜和单色器是作为日本XFEL设施SPring-8 ngstrom紧凑型自由电子激光器（SACLA）的关键光学器件开发的。光学系统的设计是为了将极强的横向相干XFEL光传输到实验站。反射镜系统提供高强度且能量范围低于15 keV的粉红色光束，而Si（111）单色仪覆盖4- 30 keV的更宽能量范围，带宽为0.01%。为了实现高稳定性和无污染环境，这些光学元件的机械设计具有高刚度和超高真空（UHV）兼容性。运行100天后，在镜面上没有观察到辐射损伤。
Beamline mirrors and a monochromator were developed as key optical devices for the Japanese XFEL facility, SPring-8 Ångstrom Compact Free Electron Laser (SACLA). The optics were designed for transporting extremely intense, transversely coherent XFEL light to the experimental stations. The mirror system delivers a pink beam with high intensity and an energy range below 15keV, while the monochromator with Si (111) covers wider energy range of 4–30keV with 0.01% bandwidth. For realizing high stability and contamination-free environment, the mechanics of these optical components were designed to have high stiffness with ultra-high vacuum (UHV) compatibility. After 100 days of operation, no radiation damage was observed on the mirror surfaces.
