We report on design and performance of a high-resolution x-ray monochromator with a spectral bandwidth of ΔE(X) ≃ 1.5 meV, which operates at x-ray energies in the vicinity of the backscattering (Bragg) energy E(H) = 13.903 keV of the (008) reflection in diamond. The monochromator is utilized for high-energy-resolution diffraction characterization of diamond crystals as elements of advanced x-ray crystal optics for synchrotrons and x-ray free-electron lasers. The monochromator and the related controls are made portable such that they can be installed and operated at any appropriate synchrotron beamline equipped with a pre-monochromator.
我们报告了一种高分辨率X射线单色仪的设计与性能，其光谱带宽为ΔE(X) ≃ 1.5毫电子伏特，工作于X射线能量附近，该能量处于金刚石(008)反射的背散射（布拉格）能量E(H) = 13.903千电子伏特附近。该单色仪用于对金刚石晶体进行高能量分辨率衍射表征，这些晶体是同步加速器和X射线自由电子激光的先进X射线晶体光学元件。该单色仪及相关控制装置设计为便携式，以便能够安装并在任何配备了前置单色仪的合适同步加速器光束线上运行。
