摘　　要：兰州重离子加速器冷却储存环主环的离子注入方式包括剥离注入和多圈多次注入。在剥离注入中,带电离子通过碳膜后的电荷态分布对注入效率有较大影响。本工作对离子通过碳膜后的电荷态分布进行了测量,并阐述了兰州重离子加速器冷却储存环上剥离器的应用。给出了离子通过碳膜后电荷态分布的测量结果。Charged ions may be injected into the CSRm by means of the charge stripping injection or the multiple multi-turn injection. The charge state distribution of the ions passing through the carbon foil has great influence on the performance of the accelerator and thus plays a key role in the charge stripping injection. It＇s found that the charge state distribution is dependent on the thicknesses of the carbon foil and the energy of the ions. In present work, the carbon stripper was applied to HIRFL-CSR and the best optional charge state distribution was measured.
