    • A flat-type cold cathode electron gun is provided to focuss an electron beam emitted from the cold cathode electron gun by using a focuss lens of a simple structure, thereby implementing a micro electron gun. An electron source(100) has a cold cathode for emitting an electron, and an electron beam emitted from the electron source is focussed and accelerated by a grid(200). The electron beam is decelerated by a first flat-type opening(300), and the electron beam passing through the first opening is accelerated by a second flat-type opening(400). The deceleration and acceleration of the electron beam are performed by a DC power source. An additional DC power source is provided between the first opening and the second opening.
    • 提供一种扁平型冷阴极电子枪,通过使用简单结构的聚焦透镜来聚焦从冷阴极电子枪发射的电子束,从而实现微电子枪。 电子源(100)具有用于发射电子的冷阴极,并且从电子源发射的电子束被栅格(200)聚焦和加速。 电子束通过第一扁平开口(300)减速,并且通过第一开口的电子束通过第二扁平开口(400)加速。 电子束的减速和加速由直流电源进行。 在第一开口和第二开口之间设置一个附加的直流电源。
