1 mplementat . m Status of the Global anc , oca 1 Beam Position Feedback Systems - for the Advanced Photon Source Storage Ring *


The Advanced Photon Source ( A P S ) is implementing an extensive beam position feedback system for both global and local stabilization of particle and photon beams based on digital signal processing. The description and operational experience of the system will be given in this paper. In particular, we will discuss the underlying fundamental principles… (More)
