Commissioning results of the APS storage ring RF beam position monitors

The commissioning of the 360 rf beam position monitors (BPMs) in the Advanced Photon Source (APS) storage ring (SR) is nearing completion. After using the single-turn capability of the BPM electronics in the early ring commissioning phase, resolution measurements versus current and bandwidth were successfully performed. In the standard SR vacuum chamber geometry, the resolution was measured with beam as 0.16{mu}m{center_dot}mA/{radical}(Hz). For the insertion device vacuum chamber geometry, the resolution was measured to be 0.1{mu}m{center_dot}mA/{radical}(Hz). Since the photon beam stability requirement for the users is only 4.5 microns rms in the vertical direction, invesgations of rf BPM offset versus current and bunch pattern have also been initiated. Both single bunch and multibunch beam patterns with varying intensity were used to determine offset stability for both the global and the local orbit feedback applications. {copyright} {ital 1997 American Institute of Physics.}
