Cold cathode is applied as the important component in the crossed-field amplifier ( CFA) and has critical requirements for cold cathode materials. 冷阴极作为微波放大管的核心组件,它对冷阴极材料有着严格的技术要求。
Simulation and Modeling of Self-Modulated Re-Entrant Beam Crossed-Field Amplifier 自调制重入式正交场放大器的模拟设计
A physical model and related formulas for the calculation of small-signal gain and phase shift in a severed injected-beam crossed-field amplifier are presented in this paper. The analysis is based on the linear theory of thin beam CFA with the space charge effect included. 本文应用计及空间电荷效应的小信号薄电子注理论,建立了有切断区的注入式正交场放大器的物理模型,并导出了其增益及相移计算公式。
