摘要：
The transmission of highly charged Xe and Ne ions through polycarbonate (PC) nanocapillaries with multiple holes (m-PC) was investigated at the Institute of Modern Physics (IMP) in Lanzhou. In particular, Au films were evaporated on both the front side and the back to prevent the surface from charging up. The time effect was observed and the charging up model in an insulating nanocapillary was employed to explain the phenomenon. It was found that more than 98% of the transmitted ions remained in their initial charge state. The guiding effect and the relationship between the charge state and the critical angle were also studied.
