Bunch by Bunch Feedback System Review

Bunch-by-bunch feedback (BBF) is a system designed to control the betatron or synchrotron oscillation of each bunch independently. It not only serves as a tool to dampen these oscillations, primarily for the suppression of beam instabilities, but also to excite individual bunches independently and to record their position or timing on a bunch-by-bunch, turn-by-turn basis. This paper reviews the applications of BBF presented at the I.FAST Workshop 2024 on Bunch-by-Bunch Feedback Systems and Related Beam Dynamics
