Beam-tracking studies with RINGBEARER II

Abstract

This report presents results from the RINGBEARER II linearized monopole/ dipole particle simulation for an intense relativistic electron beam propa gating in a gas near three types of channels: 1) pre-existing conductivity, 2) density, and 3) density with pre-existing conductivity. Comparisons are made with earlier analytic results for the initial conditions for the pre existing conductivity channel. DISCLAIMER
