【Abstract】 In this paper we report the application of super-aligned carbon nanotube field emission electron source in the neutralizer of RF ion thruster. The electron source can emit 1.5 mA current at 400～500 V to meet the neutralization requirement of the RF ion thruster, and it has excellent in-orbit performance with advantages of low emission voltage, large emission current, high stability and high reliability.更多还原
