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.
