Abstract :
A magnetron injection electron gun based on carbon nanotube cold cathode is developed in this paper, which is designed for a 0.22THz TE03 mode gyrotron. The experimental results of electron gun show that the maximum beam current reaches 30mA and an average radius of 1.2mm beam spot are achieved by using ITO glass. And the beam current density is increased 100 times.
