Recent Developments in Orbit Feedback on the SRS at Daresbury

摘要

Local vertical and global horizontal orbit feedback systems have been in routineused on the SRS at Daresbury since 1994 and are now an essential element in providing a stable photon beam to experimental stations. A brief review of the latest operational performance of these systems is followed by details of the latest enhancements under development including automatic global orbit feedback during an energy ramp and techniques for improving the performance of the vertical feedback system.
