Status of Digital Bunch-by-Bunch Feedback Systems at DELTA and their Application as Diagnostics Tools.* — •Markus Höner, Holger Huck, Shaukat Khan, Robert Molo, Andreas Schick, Peter Ungelenk, and Maryam Zeinalzadeh — Center for Synchrotron Radiation (DELTA), TU Dortmund University, 44227 Dortmund, Germany

Digital bunch-by-bunch feedback systems allow to detect and counteract longitudinal as well as transverse multi-bunch instabilities. Beam current-dependent grow-damp measurements have been performed in order to characterize these instabilities at the DELTA storage ring. The longitudinal feedback system is used permanently during the operation of the new short-pulse facility in order to damp longitudinal bunch oscillations. Besides that, all three feedback systems are in use as excellent diagnostics tools, e.g. to investigate the injection process or to take data during sudden beam loss for post-processing. * Work supported by the BMBF.
