Space-charge effects in long coaxial vacuum transmission lines

Abstract

A new two−dimensional time-dependent electromagnetic particle code is applied to the high-voltage pulsed power flow problem in a long self-magnetically insulated coaxial line. It is found that the current leakage occurs only near the front of the voltage pulse, that energy transport is very efficient at high voltages, and that the electrons in the insulated region do not get close to the anode.
