Abstract
The vacuum system of the 8-GeV storage ring planned by the Riken-Jaeri SRF (Synchrotron Radiation Facility) design team is presented. The vacuum system is designed to maintain a beam-on operating pressure of 1 ntorr or less to achieve an electron (or positron) beam life of approximately 24 h. Particular attention is given to the various vacuum chamber components and to the flexible vacuum chamber for an insertion device with an RF contact. A stress analysis of the chamber and crotch together with a thermal analysis is discussed
