Status of the Bunch-by-Bunch Fast-Feedback System at ANKA — •Sebastian Marsching, Nicole Hiller, Erhard Huttel, Vitali Judin, Benjamin Kehrer, Marit Klein, Christina Meuter, Anke-Susanne Müller, Michael Nasse, Marcel Schuh, Nigel Smale, and Max Streichert — Karlsruhe Institute of Technology

At ANKA, the synchrotron light source of the Karlsruhe Institute of Technology, a vertical bunch-by-bunch fast-feedback system is being commissioned for damping multi-bunch instabilities and performing beam-dynamics studies.

The ANKA synchrotron operates at a regular beam energy of 2.5 GeV while the ANKA injector operates at only 0.5 GeV. Thus, the beam injected into the synchrotron has to be ramped up in energy. Therefore, the fast-feedback system has to be able to damp instabilities over the whole energy range from 0.5 to 2.5 GeV.

In this talk, we summarize the progress of the commissioning process and present studies we performed on compensating effects caused by the change of beam energy.
