The transport of a beam of variously charged ions via a flat equipotential vacuum gap is theoretically described. The values of the critical beam current density are determined. The current density and the average ion charge in a beam past the gap are expressed as functions of the injected beam parameters (current density, average charge, and initial energy). Regimes featuring the effective separation of singly and doubly charged ions are found.
