Impedance studies at the Karlsruhe Research Accelerator using the Bunch-by-Bunch feedback system — •Edmund Blomley, Akira Mochihashi, Marcel Schuh, and Anke-Susanne Müller — IBPT, KIT, Karlsruhe

At the KIT storage ring KARA (KArlsruhe Research Accelerator) the impedance is influenced by several factors like in vacuum moving gap insertion devices and scrapers. Additionally, over the last several years, the vacuum chamber has been modified multiple times due to installation of new insertion devices. This contribution presents systematic studies of the impedance using long-term archive data as well as measurements using the fully digital 3D bunch-by-bunch feedback system.
