High Current Relativistic Electron Beam Propagation in High Neutral Pressure Environments

Abstract

High current intense relativistic electron beam (IREB) propagation is intrinsically unstable in high pressure environments (HPE) due to the onset of the resistive hose instability. One of the ways to reduce the growth of the hose is through beam conditioning which consists of emittance tailoring and current centroid sweep damping. In the experiments reported in this work we conditioned the SuperIBEX IREB using IFR and active B theta cells. The conditioning cells successfully stabilized the beam for approximately 20 betatron wavelengths (lambda beta) and propagation lengths exceeding 5 m.
