Conditioning Electron Beams in the Ion-Focused Regime
Abstract
Relativistic electron beams propagating through dense gas are subject to the resistive hose instability, a virulent kink instability that restricts the effective range of high-current beams. Previous studies have shown that the instability can be suppressed by centering the beam and tailoring its emittance prior to injection into the gas. One means of centering and tailoring a beam is to use short 'conditioning' cells that operate in the low pressure, ion-focused regime. In this paper, analytic models are developed to understand and assess the performance of such cells.
