Investigation of the injection into the ANKA storage ring by a turn by turn BPM system

Modern BPM electronics allow turn by turn acquisition of the position for both the injected and stored beam. This offers additional opportunities for diagnostics. In addition to the slow BPM acquisition system installed at ANKA, two LIBERA ELECTRON units (www.i-tech.si) have been installed. The system is used to investigate and optimize the Booster and the injection process into the Storage Ring. Tune and orbit in the Booster could be determined, as well as for the first turns in the Storage Ring. The stray field of the storage ring septum turned out to cause a bump of the stored beam. The settings of the kickers could be optimized for minimized orbit distortion. The phase space of the injected beam could be determined.
