RF SYSTEM RESEARCH-AND-DEVELOPMENT FOR THE PEP-II B-FACTORY

The PEP-II B factory will be a high-luminosity asymmetric electron-pos itron collider optimized for the study of CP violation [1]. It is bein g built at SLAG by a collaboration including SLAG, LBL and LLNL. The i ntegrated-luminosity needed for the experiment requires high average b eam current in the two storage rings and this creates significant chal lenges in the design of the RF system and other components. The paper describes the R and D activities in progress towards meeting these cha llenges and some of the significant achievements in the areas of RF ca vity design, higher-order mode damping, RF window design and feedback systems.
