SSRL RF System Upgrade

The Stanford Synchrotron Radiation Laboratory started operation as a parasitic light source in 1973, becoming a fully dedicated user facility in 1992. A project was approved in 1998 to upgrade the storage ring to a third generation source. In order to sustain higher current in a tightly reconfigured magnetic lattice, it became necessary to upgrade the rf system from the present 5-cell cavity to four units of single-cell cavities to be powered by one high-power or two low-power klystrons. We present an overview of the upgrade project to be completed by the year 2002
