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 non segmented 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.
