| Outline of Final Research Achievements |
To develop cluster systems of Hall thruster for high-power electric propulsion systems, evaluations of SBS systems consisting of two-head system of magnetic-layer head were performed. As a result, it is found that a cathode position influences on the thrust performance. The plume divergence results on the influence. Effects of combination of magnetic field fidrections on th plume divergence was investigated by numerical analyses. In addition, interference effets of anode-layer SBS system were observed.
