We present experimental studies of the transmission of slow 4.5 keV Ar9? ions through a single cylindrical-
shaped glass capillary of macroscopic dimension with large aspect ratio. We show that an electric
guiding field can also build-up inside a macro-scale single capillary, and thereby slow highly charged ions
can be transmitted through the macro-capillary, keeping their initial charge state in a similar manner as
for the case of nano-capillaries. Our results clearly indicate the existence of the guiding effect even in the
case of large tilt angles.
