Abstract

This paper describes the proposed low-level RF system of the positron accumulator ring (PAR), the injector synchrotron, and the storage ring of the 7-GeV Advanced Photon Source. Four RF systems are described since the PAR consists of a fundamental frequency system at 9.8 MHz and a harmonic system at 117 MHz. A block diagram of an accelerating unit is shown and descriptions of various control loops are made (including amplitude control, phase control, and cavity tuning control). Also, a brief overview of the computer interface is given
