Transmission of highly charged ions through a glass capillary with the outlet size of 0.1 mmϕ was observed. Highly charged ions (HCIs, Ar9＋∼Ar14＋) were extracted from an electron beam ion source with the acceleration potential of 3 kV, and HCI beam in the 10 pA range was injected into the glass capillary. Transmitted current was in the several pA range, and the current density was about 5 times higher than the incident current density, however, it is necessary to improve unstable aspects such as limited operating time.
