Commissioning of Digital Bunch-by-Bunch Feedback Systems at DELTA and their Application as Diagnostics Tools.* — •Markus Höner, Mohammed Bakr, Holger Huck, Shaukat Khan, Robert Molo, Andre Nowaczyk, Andreas Schick, Peter Ungelenk, and Maryam Zeinalzadeh — Center for Synchrotron Radiation (DELTA), TU Dortmund University, 44221 Dortmund, Germany

Digital bunch-by-bunch feedback systems have been recently installed and commissioned at the synchrotron radiation source DELTA operated by the TU Dortmund University. The feedback systems allow detecting and counteracting longitudinal as well as transversal multi-bunch instabilities. Beam current-dependent grow-damp measurements have been performed in order to characterize these instabilities. In addition to that, the feedback systems are used as diagnostics tools to study the oscillation amplitudes of different electron bunches during the injection process.
