【摘要】:目前國(guó)內(nèi)電子回旋共振(ECR)中和器的研究存在電子束流不能連續(xù)引出的問(wèn)題,為此通過(guò)改進(jìn)中和器天線結(jié)構(gòu)及優(yōu)化電子引出孔徑來(lái)改善中和器的性能。試驗(yàn)結(jié)果表明:中和器結(jié)構(gòu)改進(jìn)及優(yōu)化后其電子束流可以隨著接觸電壓的升高而連續(xù)變化,同時(shí)提高了中和器的推進(jìn)劑利用效率、降低了電子產(chǎn)生損耗。推進(jìn)劑利用效率和電子產(chǎn)生損耗在中和器結(jié)構(gòu)改進(jìn)前后分別為1.278 9和194.573 W/A,1.659 8和126.3 W/A。試驗(yàn)還通過(guò)靜電探針診斷出中和器耦合天線附近等離子體密度分布在1.72×10~(17)~12.1×10~(17)m~(-3)范圍內(nèi)。
[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).
