本文描述了一台用于真空紫外区工作的24米球面光栅单色仪。该仪器采用两个就地可互换的光栅，光谱范围为44至410ä(280至30 eV)。光束线光学系统由1：1预聚焦环形镜、带可移动出射狭缝的球面光栅单色器和再聚焦镜组成。报道了由实验站的测试测量确定的光子通量、分辨率和高阶贡献。
A 24-m spherical grating monochromator designed for operation in the VUV region at the Photon Factory is described. With two in situ interchangeable gratings the instrument covers the spectral range of 44 to 410 Å (280 to 30 eV). The beamline optical system consists of a 1 : 1 prefocussing toroidal mirror, a spherical grating monochromator with a movable exit slit, and refocussing mirrors. The photon flux, resolution and higher-order contributions are reported as determined by test measurements at the experimental station.
