在分子科学研究所UVSOR装置的弯曲磁体光束线BL2B2上搭建了18 m高分辨率、高光子通量的球面光栅单色仪。单色仪覆盖 20-200eV 的能量范围，具有三个光栅。通过稀有气体原子（He、Ar和Kr）的离子产额谱估计，在光子通量为1×1010photonss−1、环电流为100mA的条件下，分辨能力（E/ΔE）为2000-8000。光子能量为45.6eV时含有7%的二阶光。
An 18 m spherical grating monochromator with high resolution and high photon flux has been constructed at the bending magnet beamline BL2B2 of the UVSOR facility in the Institute for Molecular Science. The monochromator covers the energy range of 20–200eV with three gratings. The resolving power (E/ΔE) has been estimated by ion yield spectra of rare gas atoms (He, Ar and Kr) to be 2000–8000 under the conditions of a photon flux of 1×1010photonss−1and a ring current of 100mA. A second-order light of 7% is contained at a photon energy of 45.6eV.
