VUV·SX high-brilliance light source

A third-generation VUV and soft X-ray ring (VSX ring in short) with a low emittance of several nm·rad is being designed at the Institute for Solid State Physics (ISSP) of the University of Tokyo, in close collaboration with the Photon Factory of KEK. The proposal for constructing the light source facility (VSX Light Source) is now in preparation for submission to the government. A brief description is presented on the facility storage ring and injectors as well as a newly organized body for construction and utilization of the facility. (J.P.N.)
