| Outline of Final Research Achievements |
To develop cluster systems of high power electric propulsions, a Hall thruster system consisting of two magnetic-layer-type heads were developed. Investigations of fundamental operational characteristics and thrust performance were performed. The measured discharge current profiles of the two heads suggested that the amplitude and the phase relation of 20 kHz-range discharge current oscillations were strongly influenced by interferences between operations of the two head. The results of the thrust measurements showed that the thrust depended on the combination of the applied magnetic field directions and became higher for opposite directions. It was also found that the difference in the thrust decreased as the discharge voltage increased.
