Controlling the plasma potential distribution in segmented-electrode hall thruster

Research output: Contribution to journal › Article › peer-review

Abstract

Segmented electrodes and ceramic spacers (CSs) placed along the Hall thruster channel are shown to produce strong modifications of axial and radial plasma potential distributions as compared to conventional nonsegmented thruster. These modifications are associated with differences in secondary-electron-emission properties of materials used for electrodes and CSs and correlate with plasma-plume divergence.
