摘要
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。
Ongoing life-test of hollow cathode has been introduced. The result indicated that the performance of hollow cathode has not show degradation trend after 3 000 hours life-test. The result has also showed the hollow cathode has good antipoisoning traits under air exposure condition.
