Effect of Temporal Current Modulation on the Tracking Force Acting on a Relativistic Electron Beam in an Ohmic Plasma Channel

Abstract

The effect of the current rise time in a relativistic electron beam pulse on the tracking force exerted by the low-conductivity Ohmic plasma channel on the beam has been analyzed using the “hard” beam model. It is shown using numerical analysis that an increase in the beam current rise time substantially reduces the tracking force considered here.
