Evaluation of a Bunch-by-Bunch Fast Feedback System at ANKA — •Sebastian Marsching, Nicole Hiller, André Hofmann, Erhard Huttel, Vitali Judin, Benjamin Kehrer, Marit Klein, Anke-Susanne Müller, and Nigel Smale — Karlsruhe Institute of Technology, Karlsruhe, Germany

Multi-bunch instabilities are an important limiting factor in the operation of electron storage rings. Using modern bunch-by-bunch fast-feedback systems, these instabilities can be studied and partly damped, thus pushing accelerator performance beyond limits.

At ANKA, Instrumentation Technologies' Libera Bunch-by-Bunch Fast Feedback System is currently evaluated for damping instabilities present during injection as well as during user operation.

This talk will present the results of the ongoing work regarding the damping of these instabilities and the investigation of the corresponding multi-bunch effects.
