文中给出了以正交电磁埸中的空间电荷流方程解为基础的M型电子槍的设计方法。利用复数平面中解析的连续性,可以证明求所需电极的正确形状是可能的。这种设计给出了一种与法国的短槍相似的电子槍,其最大优点在于,可以预计从电子槍中发射出来的电流以及阴极上的电流密度。文中同样表明,对空间电荷流的解作一定的近似,即可设计出一种新型电子槍,即具有极高收歛度的长槍,该电子槍的理论非常简单,并且电极形状完全能用解析方式给出。
In this paper, the design method of M-type electron gun based on the solution of space charge flow in orthogonal electromagnetic wave is given. Using the continuity of the resolution in the complex plane, it is possible to demonstrate that it is possible to find the correct shape for the desired electrode. This design gives an electron gun similar to a French gun, with the biggest advantage being that the current emitted from the electron gun and the current density at the cathode can be predicted. The paper also shows that the space charge flow solution to make a certain approximation, you can design a new type of electron gun, that is, with a very high degree of convergence of the long gun, the electron gun theory is very simple, and the electrode shape can be resolved Way given.
