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.

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

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 designand procurement of CR components
