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.

GSI Helmholtzzentrum für Schwerionenforschung GmbH Collector Ring - CR

GSI Helmholtzzentrum für Schwerionenforschung GmbH Progress on the Collector Ring  The Technical Design Report of the CR has been updated and approved in February  In-kind Review Board (IKRB) meeting ( ) assigns a major part of the CR components (63 %) to Budker Institute of Nuclear Physics (BINP)  Contract on transfer of the CR system responsibility to BINP is prepared. After Council decision it can be signed.  BINP and GSI make good progress in design and procurement of CR components
