- 摘要:
- 空心阴极和离子推力器或霍尔推力器的耦合放电与其和平板阳极的独立放电有明显差异,主要表现为工作特性不同和寿命大幅缩短等。基于空心阴极的设计寿命与其在推力器中实际寿命显著不同的事实,归纳分析了空心阴极在推力器中寿命缩短的主要原因,总结了推力器中电场、磁场、背景中性气体密度等因素对空心阴极寿命的影响机理研究现状,并提出需要进一步深化的主要研究内容。
- Abstract:
- The coupling discharge of hollow cathode in ion thruster and hall thruster is significantly different from its independent discharge with flat electrode, mainly manifested in different working characteristics and greatly shortened service life.Based on the fact that the design life of hollow cathode is significantly different from its actual life in thruster, the main reasons for the shortening of the life of hollow cathode in thruster were analyzed, the influence of electric field, magnetic field and background neutral gas density on the life of hollow cathode was summarized, and the main research contents that need to be further deepened were put forward.
