Status of bunch-by-bunch feedback systems at the DELTA storage ring used for electron beam diagnostics* — •Markus Höner, Svenja Hilbrich, Holger Huck, Maryam Huck, Shaukat Khan, Arne Meyer auf der Heide, Carsten Mai, Robert Molo, Helge Rast, Andreas Schick, Malte Sommer, and Peter Ungelenk — Center for Synchrotron Radiation (DELTA), TU Dortmund University, 44227 Dortmund, Germany

At the 1.5-GeV electron storage ring DELTA (TU Dortmund), bunch-by-bunch feedback systems are in use to analyze and counteract transverse and longitudinal multi-bunch instabilities. An automatic readout of bunch position data allows a real-time mode analysis during machine operation, which is available in the control room. In dedicated machine shifts an excitation of particular multi-bunch modes allows further investigation of beam stability and determination of natural damping times of all modes even below the instability threshold.

Besides that, a chromaticity-dependent single-bunch instability will be discussed and first bunch-by-bunch data taken from the synchrotron (BoDo) will be shown.
