Proceedings of the 2005 Particle Accelerator Conference.
A particle accumulator ring (PAR) is used at the Advanced Photon Source (APS) to collect multiple linac bunches and compress them into a 0.3-ns single bunch for booster injection. A 9.77-MHz fundamental and a 117.3-MHz harmonic rf system (RF12) are e
