Magnetically insulated theory with both electron and ion flows

Abstract

Both the ion emission from anode surface and the electron emission from cathode surface may occur in the magnetically insulated transmission line (MITL) with a very high pulsed power and a very large current density. A model for the MITL with both electron and ion flow is developed. In this model, physical quantities (such as space-charge sheath thicknesses and flow currents) in the MITL are theoretically analyzed, and the specific expression for the voltage on the line by the terms of currents is derived. Furthermore, particle-in-cell simulations are carried out to verify the theoretical results.
