碳纳米管阴极强流脉冲发射放气质谱分析
Outgassing mass spectrum analysis with intense pulsed emission of carbon nanotube cathode
摘要
Abstract
The outgassing mass spectrum property with intense pulsed emission of the carbon nanotube（CNT） cathode is investigated on a 2 MeV linear induction accelerator injector by using the quadrupole mass spectrometer.The results show that the cathode has a capability of desorbing gases from the CNT cathode under pulsed high voltage.There are significant CO2,N2（CO） and H2 desorbing gases which play an important role in the formation of the cathode plasma.The mechanism of electron emission of CNT cathode is plasma-induced field emission,rather than explosive field emission,which is proved by analyzing the desorbed gases component.关键词
