Abstract :
The maximum electron current at ANKA is presently limited by multi-bunch instabilities during injection and ramping. In order to overcome this barrier an analog transverse multi-bunch feedback system was developed and commissioned. During the test phase of the feedback operation a beam stabilization by the feedback system was clearly demonstrated. In the first six months of operation the number of total or partial beam losses related to instabilities was distinctly reduced.
