Abstract

A description is given of the low-level RF circuitry for the several 1-MW RF systems for the 7-GeV Advanced Photon Source (APS) booster synchrotron and storage ring. The control circuits, including phase and amplitude feedback loops for the acceleration voltage, and a phase feedback loop for the klystron phase ripple are described. Initial operation of the systems are outlined. Synchronization of the voltages for bucket-to-bucket beam transfer between the two accelerators is also described with data showing typical operation
