电荷剥离装置是串列加速器的重要组成部分。与固体剥离器和普通气体剥离器相比
循环气体剥离系统具有束流能散度增加少、等效剥离厚度高、束流接受度大和加速管内真空度高等优点。最近
为北京大学6MV串列加速器研制的循环剥离系统投入了使用
本文介绍该系统的基本结构、安装调试、束流实验以及由于加速器性能提高而得以开展的应用工作。
Recirculation gas stripper has the advantages of high beam acceptance
high gas density in stripper tube comparing with original gas stripper and less increase of beam emittance comparing with foil stripper. Recently a new recirculation gas stripper has been designed and manufactured for the EN tandem at Peking University. The structure
installation and performance of this stripper are described in this paper. Based on this improvement
the beam transmission of 10Be3+ has been increased from 5% to 11%
heavy ions with high charge state up to 17 have also been obtained for fabricating nano structure with ion track technology.
