摘要： PURPOSE: An electron beam focusing electrode and an electron gun using the same are provided to focus the electron to an anode direction separated from a cathode by passing the electron through the penetration hole of the electron beam focusing electrode. CONSTITUTION: A cross section of a second surface(32) of a penetration hole(33) emitting the electron is larger than the cross section of a first surface(31) of the penetration hole. The cross section of the penetration hole is inclined to the progressing direction of the electron beam passing through the inside of the penetration hole. A protrusion(34) is formed in at least one side of the penetration hole. The orbit of the electrons passing through the inside of the penetration hole is controlled by the protrusion. The distortion of the electric field is decreased in an edge part of the electron beam. The uniformity of the electron beam from the electron gun is improved.
摘要翻译：目的：提供电子束聚焦电极和使用该电子束聚焦电极的电子枪，以通过使电子通过电子束聚焦电极的穿透孔将电子聚焦到与阴极分离的阳极方向上。构成：发射电子的穿透孔（33）的第二表面（32）的横截面大于穿透孔的第一表面（31）的横截面。穿透孔的横截面向穿过穿透孔内部的电子束的前进方向倾斜。突起（34）形成在贯通孔的至少一侧。穿过穿透孔内部的电子的轨道由突起控制。在电子束的边缘部分，电场的变形减小。来自电子枪的电子束的均匀性得到改善。
