Example: Slow Extraction to CBM Experiment Reference Production chain for operation in MSV Beam Parameters UNILAC SIS18 SIS100 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 postprocessing) as limited by ion source. HEBT transfer and stripping of Au65+ ions to Au79+ ions.

Collector Ring - CR

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 design and procurement of CR components
