The BEPC beamline 4B9B is intended for VUV-SX photoelectron spectroscopy and other soft x-ray applications. The beamline optical system consists of a focusing mirror system and a VUV-SX spherical grating monochromator with four gratings, which cover a large spectral range 10--1100 eV. Three laminar gratings (1100, 500, and 200 lines/mm) with a 57--m radius are used at a 174/degree/ including angle, and the other grating (600 lines/mm) with a 6-m radius is used at a 142/degree/ including angle to be suited for low-energy use. Scanning is achieved by the rotation of the grating, and a pair of stepping motor-driven slits follow the Rowland circle to improve the monochromator's performance. The optical design and ray tracing results about this monochromator are described
