Abstract

We developed high current electron emission carbon nanotube cold cathode electron sources for high power vacuum devices. To develop high power devices with electron beam, electron emission current is most important. More than 100 rnA electron emission current achieved with the optimized CNT fabrication process and its structure. The electron emission current limited by the conductivity of CNT emitters, the higher conducting emitters show higher electron emission current. Detail on the fabrication process and performance of electron beam would be presented.
