  24. Example: Slow Extractionto 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. SIS100 • Injection of 4 batches from SIS18 needs ~1.1 s • Acceleration to 11 GeV/u • KO-Extraction, spill length 1 - 10 s • Repetition Time ~3 - 13 s

  25. Collector Ring - CR

  26. Progress on the Collector Ring • The Technical Design Report of the CR has been updated and approved in February 2014. • 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) • 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 designand procurement of CR components
