本文扼要介绍了射频触发的冷阴极正交场放大器的工作情况,并提出了电子注是怎样建立起来的问题,因为这要求在固有的未进行相位群聚的区域内维持电子连续碰撞阴极达20次以上。数字计算给出了部分的回答,指出重复碰撞的电子注的速度不是E/B,从而得出一个新的相位聚焦机理。发现在一个计算的电压范围内(和测量值很一致),即使没有精确的同步,电子注也能建立起来。叙述了两个计算机程序的原理,一个用于空间电荷的作用可以忽略的建起区域,另一个用于空间电荷有重要作用的过渡区和功率产生区域。得出了轰击阴极电子的速度和方向的定量结果,空间电荷密度的变化对其有显著影响。
This article gives a brief overview of RF-triggered cold cathode orthogonal field amplifiers and addresses the issue of how electron injection can be built because it requires that the electron be continuously impinging on cathodes up to 20 in areas that are not inherently phase-agglomerated Times or more. The numerical calculation gives a partial answer, pointing out that the velocity of the repeated electron collisions is not E / B, resulting in a new phase focusing mechanism. It was found that within a calculated voltage range (very consistent with the measured value), the electronic injection can be established even without accurate synchronization. Describes the principles of two computer programs, one for the built-up area with negligible contribution to space charge and one for the transition and power generation areas where space charge plays an important role. The quantitative results of the velocity and direction of the bombardment of the cathode were obtained, and the change of the space charge density had a significant effect on it.
