Outline of Final Research Achievements

To understand anomalous electron transport in a Hall thruster, plasma turbulence inside the acceleration channel was observed using a E-band microwave interferometer. The dependence of the amplitude of the turbulence on magnetic flux density, and the relations between the turbulence and other plasma perturbations and between the turbulence and the discharge current, were investigated through power spectral density and bi-coherence analysis. The turbulence has a positive relation to the discharge current, leads to anomalous electron transport inside the acceleration channel, and is coupled with ionization instability. Low frequency perturbations (several hundred Hertz) were observed; this low frequency perturbation could be a key to suppressing plasma turbulence. In addition, we showed usefulness of the short pulse width laser (picosecond laser) diagnostics for the measurement inside the Hall thrusters.

Academic Significance and Societal Importance of the Research Achievements

本研究の最大の成果はホールスラスタの異常輸送にはこれまであまり注目されてこなかったプラズマ乱流が影響していることを実験的に示したものであり、異常輸送を抑制し、推力電力比向上にはこのプラズマ乱流の制御が鍵となることを示したことである。この成果をさらに発展させ、プラズマ乱流の物理機構を解明することで、異常輸送の抑制が可能になり、推力電力比90 mN/kWを超えるホールスラスタ開発への道が開ける。このホールスラスタは宇宙利用コストの大幅な削減を通して安全安心社会の構築に貢献する。
