Therefore, the linear hot cathode 2 can be placed at a position sufficiently close to the electron beam control electrode 3, depending on the design conditions, without the electron beam control electrode 3 and the position regulating member 4 coming into contact with each other. I can and
Moreover, the linear hot cathode 2 can be arranged on the same plane as the electron beam control electrode 3.

用的効果は大である。(Effects of the Invention) According to the present invention, the electron beam control electrode has the electron beam passage hole and the escape hole integrally formed so as to be adjacent to each other or to be continuous. Alternatively, since the linear hot cathode is no longer in contact with the electron beam control electrode, the linear hot cathode can be placed sufficiently close to the electron beam control electrode, or it can be placed on the same plane as the electron beam control electrode. The practical effects are great, such as increasing the degree of freedom in design.
