The Rf Phase System of the Slc ’

The phases of the RF throughout the SLC accelerator complex play an important part not only in the energy and energy spread of the beams at the end of the liiac, but also in the production process of both electrons and positrons. Proper machine operation requires that certain phase relationships be maintained between the RF systems of the electron source, the electron and positron damping rings, the linac, and the positron source. This paper presents an overview of the interplay of the various RF phases throughout the SLC accelerator complex as well as describing various hardware and software inter-connections which have been made to facilitate control of the system as a whole. In addition, a description is given of RF phase monitoring required for system control. Operational experience and future plans are also discussed.
