Title: Performance of the beam position monitor system for the SLAC PEP-II {ital B} factory

Abstract

The beam position monitor (BPM) system for the SLAC PEP-II {ital B} Factory was designed to measure the positions of single-bunch single-turn to multibunch multi-turn beams in both rings of the facility. Each BPM is based on four button-style pickups. At most locations the buttons are connected to provide single-axis information ({ital x} only or {ital y} only). Operating at a harmonic (952 MHz) of the bunch spacing, the BPM system combines broadband and narrowband capabilities and provides data at a high rate. The active electronics system is multiplexed for signals from the high-energy ring (HER) and low-energy ring (LER). The system will be briefly described; however, the main purpose of the present paper is to present operational results. The BPM system operated successfully during commissioning of the HER (primarily) and the LER over the past year. Results to be presented include on-line calibration, single-bunch single-turn resolution ({lt}100 {mu}m), and multibunch multi-turn resolution ({lt}3 {mu}m), multiplexing, and absolute calibration. Thus far, the system has met or exceeded all the requirements that have been tested. The remaining requirements will be tested when both rings are completed and commissioned this summer. In addition, typical results of beam physics studies relying on themore » BPM system will be presented. {copyright} {ital 1998 American Institute of Physics.}« less
