摘要

离子噪声是微波管中一个重要的性能指标。它表现为相位的松弛振荡。本文采用混合模型对离子噪声现象进行了分析，提出了抑制和消除离子噪声的方法。为了降低离子噪声，除了提高真空度和电子束聚焦水平等常用方法外，还讨论了另一种更实用的方法——在管中增加电极环，并通过数值模拟(PIC)证明了这是一种很好的方法。

The way of depressing and eliminating the ion noise in microwave tubes

Ion noise is an important figure of merit in microwave tube. It behaves manifest as a relaxation oscillation of phase. In this paper, we used hybrid model to analyze the noise phenomena and the way of depressing and eliminating the ion noise. To reduce the ion noise, besides the commonly way such as improving the vacuum degree and electronic beam focus level, another more practicability technique of adding electrode ring in tube is discussed and the numeric simulation (PIC) proved it is a well method.
