Example: Slow Extraction to CBM Experiment The Au beam is produced in the following steps: UNILAC • Au 4+ is produced in the MEVVA source, • Au 25+ is produced in the UNILAC gas stripper at 1. 4 Me. V/u, • Accelerated in UNILAC to 11. 4 Me. V/u , • Stripping of Au 25+ ions to Au 65+ ions in the TK Stripper, • 4 pulses are produced in ~1 s (2. 7 Hz) . SIS 18 • Accelerates each pulse to 1 Ge. V/u, • Needs ~1. 6 s for 4 batches (including pre- and post processing) as limited by ion source. HEBT • transfer and stripping of Au 65+ ions to Au 79+ ions. SIS 100 • Injection of 4 batches from SIS 18 needs ~1. 1 s • Acceleration to 11 Ge.

Progress on the Collector Ring Ø The Technical Design Report of the CR has been updated and approved in February 2014. Ø In-kind Review Board (IKRB) meeting (01. 04. 20014) assigns a major part of the CR components (63 %) to Budker Institute of Nuclear Physics (BINP) Ø Contract on transfer of the CR system responsibility to BINP is prepared. After Council decision it can be signed. Ø BINP and GSI make good progress in design and procurement of CR components GSI Helmholtzzentrum für Schwerionenforschung Gmb. H
