Outline of Final Research Achievements

The potential measurement of the hollow cathode was conducted in various operation conditions. The low potential and the electron sheath near the anode was observed. This is caused by suppression of the plasma instability by high mass flow rate.
The 40% plasma acceleration by the traveling magnetic field. From this result, the demonstration of the plasma acceleration by the traveling magnetic field was succeeded. The increment of the electron temperature and the electron number density was also measured, and the separation between the acceleration by the potential gradient and the acceleration by the pressure increase is a future issue.

Academic Significance and Societal Importance of the Research Achievements

本研究でのホローカソードプルームの計測により、プラズマ中の電位勾配が流量や電流により大きく変化することが示され、電位が低く電位勾配が生じない新しい動作モードを発見した。これは、ホローカソードの長寿命化につながる発見である。
進行磁場を用いた無電極のプラズマ加速手法が本研究で初めて実証された。この加速手法は、既存の無電極加速手法に比べ高い加速効率が理論的に期待されており、今後の研究により高い効率を実証することにより、既存の電気推進機より遥かに長寿命な推進機の実用化が期待できる。これは、衛星の長寿命化や更なる高度な宇宙ミッションの実現へつながる成果である。
