Title:	Some exact results for test ion acceleration in a dynamic planar electron sheath
Abstract:	New results are obtained for relativistic acceleration of test positive ions in the laminar zone of a planar electron sheath evolving from an initially mono-energetic electron distribution. The electron dynamics is calculated against the background of motionless foil ions. The limiting gamma-factor of accelerated ions is shown to be determined primarily by the values of the ion-electron charge-over-mass ratio mu and the initial gamma-factor of the accelerated electrons. It is shown that, for mu < 1/8, a test ion can catch up with the electron front only when the initial electron gamma-factor is above a certain critical value. The dependence of this critical electron gamma value on the problem parameters is investigated.
