24 GSI Helmholtzzentrum für Schwerionenforschung GmbH Example: Slow Extraction to CBM Experiment The Au beam is produced in the following steps: UNILAC Au4+ is produced in the MEVVA source, Au25+ is produced in the UNILAC gas stripper at 1.4 MeV/u, Accelerated in UNILAC to 11.4 MeV/u, Stripping of Au25+ ions to Au65+ ions in the TK Stripper, 4 pulses are produced in ~1 s (2.7 Hz). SIS18 Accelerates each pulse to 1 GeV/u, Needs ~1.6 s for 4 batches (including pre- and post- processing) as limited by ion source. HEBT transfer and stripping of Au65+ ions to Au79+ ions.
