This document presents the results of an investigation of the interaction between an intense Relativistic Electron Beam (REB) and reduced density channels in ammonia (NH3) at 40 Torr. The channels were produced by absorption in the ammonia of energy from a pulsed CO2 laser. Two channel geometries were studied. The first employed a 2.5 cm radius channel with the nominally 1.2 cm radius REB injected coaxially. The second geometry employed an annular channel with its minimum density at 2.3 cm radius and near ambient density on axis. The REB was again injected coaxially. It was found that the conductivity induced in the reduced density channel by the REB caused large plasma currents to flow in the channel. The REB current and the plasma current flowed in opposite directions during most of the REB pulse, causing the REB to be expelled/repelled from the channel.
