Stabilizing Effect of Gas Conductivity Evolution on the Resistive Sausage Mode of a Propagating Beam

Abstract

Previous theoretical work has shown that a highly current neutralized charged particle beam propagating in a pre-ionized plasma channel of fixed conductivity is subject to a resistive sausage instability. The authors show that the instability if stabilized, for the case of beam propagation into initially unionized gas, when the effect of beam-collisional ionization on the gas conductivity is modeled fully self-consistently.
