本文研究了正交场分布发射或发射底极放大器广义的稳态非线性电子与波互作用理论。系统的方程是非线性微-积分方程,是从一维等效传输线方程,洛仑兹力方程,连续方程和泊松方程展开而来。在理论中考虑了直流、高频和空间电荷力以及底极的二次发射的影响。数字计算机的解表明,要有增益,高频激励要有个门槛值,而且考虑了空间电荷力和二次发射时增益是提高的。靠近输出端线性地减小磁场也增加增益。根据硬-核-群聚(HKB)模型的近似解指出与计算机解有极好的一致性。
In this paper, we study the generalized steady-state nonlinear electron-to-wave interaction theory of the orthogonal field distribution transmitting or transmitting bottom amplifier. The system equation is a nonlinear micro-integral equation, which is derived from one-dimensional equivalent transmission line equation, Lorentz force equation, continuous equation and Poisson equation. In theory, the effects of DC, HF and space charge forces and the secondary emission of the bottom electrode are considered. The solution of a digital computer shows that there must be a threshold for gain and high-frequency excitation, and that the gain in space charge and in secondary emission is increased. Decreasing the magnetic field linearly near the output also increases the gain. According to the approximate solution of hard-core-cluster (HKB) model, it shows that there is an excellent consistency with computer solution.
