| Abstract: | HIRFL-CSR,a flew heavy ion cooler-storage-ring system at IMP,had been in commissioning since the beginning of 2006.In the two years of 2006 and 2007 the CSR commissioning was finished,including the stripping injection(STI),electron-cooling with hollow electron beam,C-beam stacking with the combination of STI and e-cooling,the wide energy-range synchrotron ramping from 7 MeV/u to 1000 MeV/u by changing the RF harmonic-number at mid-energy,the multiple multi-turn injection(MMI),the beam accumulation with MMI and e-cooling for heavy-ion beams of Ar,Kr and Xe,the fast extraction from CSRm and single-turn injection to CSRe,beam stacking in CSRe and the RIBs mass-spectrometer test with the isochronous mode in CSRe by using the time-of-flight method. |
