【摘要】：目前国内电子回旋共振(ECR)中和器的研究存在电子束流不能连续引出的问题,为此通过改进中和器天线结构及优化电子引出孔径来改善中和器的性能。试验结果表明:中和器结构改进及优化后其电子束流可以随着接触电压的升高而连续变化,同时提高了中和器的推进剂利用效率、降低了电子产生损耗。推进剂利用效率和电子产生损耗在中和器结构改进前后分别为1.278 9和194.573 W/A,1.659 8和126.3 W/A。试验还通过静电探针诊断出中和器耦合天线附近等离子体密度分布在1.72×10~(17)~12.1×10~(17)m~(-3)范围内。
[Abstract]:At present, the research of electron cyclotron resonance (ECR) neutralizer has the problem that the electron beam can not be extracted continuously. Therefore, the performance of the neutralizer can be improved by improving the antenna structure of the neutralizer and optimizing the orifice of electron extraction. The experimental results show that the electron beam current of the neutralizer can change continuously with the increase of the contact voltage after the structure improvement and optimization, and the efficiency of propellant utilization of the neutralizer is improved and the electron loss is reduced. The propellant utilization efficiency and electron generation loss are 1.278 9 and 194.573 W / A 1.659 8 and 126.3 W / A respectively before and after the neutralizer structure improvement. The plasma density distribution near the coupling antenna of neutralizer was also diagnosed by electrostatic probe in the range of 1.72 脳 10 ~ (17) ~ 12.1 脳 10 ~ (17) m ~ (-3).
