Performance of the ESR Barrier Bucket LLRF System — •Jens Harzheim1, Dilyana Domont-Yankulova1, Michael Frey2, Kerstin Groß1, Harald Klingbeil1,2, and Dieter Lens2 — 1TU Darmstadt, Darmstadt, Germany — 2GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany
A barrier bucket (BB) RF system is currently being installed in the Experimental Storage Ring (ESR) at GSI, Darmstadt, Germany. This system will be able to provide pulsed gap voltages, enabling highly sophisticated longitudinal beam manipulations like longitudinal capture, compression and decompression or stacking of the beam.
To fulfill the high requirements on the BB gap signal, the input signal has to be predistorted. This task has to be fulfilled by the LLRF system which includes an identification of the required RF system parameters. Additionally, adiabatic amplitude ramps and phase shifts are required for the intended beam manipulations and need to be performed by the LLRF system. The ramps will be provided by the FAIR Central Control System (CCS).
In this contribution, the topology of the ESR BB LLRF System is presented together with measured performance results for the different functionalities requested of the system.
