Abstract

The Super SOR is a third-generation VUV and soft X-ray light source that is being designed at the University of Tokyo. Eight insertion devices (ID) including a 27-m long undulator will be installed in the ring. Since the ring has a very narrow acceptance for beam loss by collision with residual gases, the vacuum system is required to achieve operation pressure of 10^-9 Pa range in order to guarantee a long beam lifetime. According to the designed lattice, the pump location and pressure distribution was examined by a simple calculation. Beam chambers should be equipped with high pumping speed, especially in arc sections. The chambers for arc sections and insertion devices have been designed. Some vacuum components were manufactured for trial and examined
