提出了一种自聚焦场致电子发射器,并对其进行了有限元模拟。在所提出的电子发射器中,栅电极被放置在中心并被阴极包围。因此,栅电极不仅要从阴极引出电子,而且要聚焦电子束。模拟结果表明,电子束的色散明显减小。
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.
