  • Abstract
    In this paper, a self-focusing field electron emitter was proposed and simulated with finite element method. In the electron emitter proposed, the gate electrode is placed on center and surrounded by cathode. Therefore, gate electrode is not only to extract the electron from cathode, but also to focus the electron beam. The simulated results show a significant decrease of the dispersion of electron beam.
