文摘Charge stripping is employed to produce multi-charged ions for injecting the cooling storage ring.After penetrating through the carbon foil,the widened distribution of ion charge states poses a limit to the ion injection.Therefore,the carbon foil plays a key role in the charge stripping injection.In this paper,four strippers for Heavy Ion Research Facility at Lanzhou(HIRFL) and Cooling Storage Ring(CSR) are introduced.The charge state distribution of the stripped ions is measured and the stripping efficiency of the foils is investigated.The experimental results are consistent with the theoretical values.
