| Outline of Final Research Achievements |
Cross-field electron transport in Hall thruster was investigated using experimental and nuemerical methods to improve the performance of Hall thruster and the accuracy of plasma simulation. As typical results obtained in this study, the experimental evaluation of 100-W class Hall thruster demonstrated that the discharge channel narrowing required an increase in the magnetic field strength in order to restrict the increase in the cross-field electron transport. The experimental evaluation of 2-kW class Hall thruster demonstrated that low discharege channel erosion rate was achieved using the magnetically shielding configuration. In addtion, the pole-piece interactions with the discahrge plasma affected cross-field eletron transport in Hall thruster.
