Global orbit feedback utilizing analog and digital technologies

Abstract

A bst racrAt the,'NSLS, an analog global orbit feedback system is used in regular operations, and a digital global orbit feedback system is available in machine physics studies on the X-Ray Ring. Here, we discuss the relative merits of utilizing analog and digital technology in orbit feedback. Results of experiments are reported characterizing the performance of our analog and digital systems when operated individually or together. We give our thoughts on plans for future development of the orbit feedback systems at the NSLS.
