COMMISSIONING OF CSR IN LANZHOU

is consists of the ECR ion source, cyclotron of SFC, SSC, and CSRm, CSRe, had been installed and started commission from 2005. Two injection modes of the stripping injection and MMI with electron cooling were tuned successful. The typical gains of accumulation from 7 to 60 were obtained by single multi-turn injection or multiple multi-turn injections (MMI) respectively. The beam momentum spread typical from 4×10 -3 is cooling to 2×10 -4
