[en] Transmission of highly charged ions through microcapillaries is studied theoretically by a classical trajectory simulation based on the classical-over-the-barrier model. The interaction of highly charged ions with the internal surface of the capillary is treated within the framework of dielectric response theory. We find the resulting charge state distribution of transmitted projectiles in good agreement with measurements. We analyze the angular distributions and the distribution of the mean occupation numbers of n shells of highly charged ions. We also present theoretical results of the energy loss of the highly charged ions undergoing distant collisions at grazing incidence angles with the internal surface of the microcapillary target.
