介绍了兰州物理研究所正在进行的离子发动机空心阴极寿命试验。试验表明,该空心阴极在经过3 000 h放电工作后,状态稳定,未见衰退趋势。研究结果还表明,该空心阴极暴露大气后具有良好的抗中毒能力。
This paper introduces the ongoing hollow cathode life test of ion engine in Lanzhou Institute of Physics. Experiments show that the hollow cathode after 3 000 h discharge work, the state is stable, no declining trend. The results also show that the hollow cathode has good resistance to poisoning after being exposed to the atmosphere.
