Abstract

We report unprecedented transmission experiments of 3 keV [Formula presented] ions through capillaries of 100 nm diameter and [Formula presented] length produced by etching ion tracks in a polymer foil. We studied foils tilted up to [Formula presented] for which the incident ions are forced to interact with the capillary surface. Surprisingly, the majority of [Formula presented] ions were found to survive the surface scattering events in their initial charge state. The angular distributions of the transmitted particles indicate propagation of the [Formula presented] ions along the capillary axis. This capillary guiding of the [Formula presented] ion provides evidence that the inner walls of the capillaries become charged and electron capture from the surface is suppressed in a self-organizing process.
