Consequently the beam transmission problem is solved well. The general design curves of microwave plasma drift tube are developed by the theory and they can be used for development of the plasma microwave devices. Ion channel, as a important phenomenon in the interaction between electron beam and plasma, is first introduced into the study of PASOTRON, to replace the concept'plasma channel'used in general plasma microwave devices. A model is created to describe the channel performance. The channel is not stable, it is oscillatory and the oscillation frequency is larger than that of plasma.

作为电子束与等离子体相互作用的一个重要现象，本文首次将离子通道的概念引入到了PASOTRON的研究中，以区别常规的等离子体通道概念，并通过建立的模型推出离子通道并非一稳定规则的通道，而是具有振荡特性，振荡频率高于等离子体频率，推出了当满足一定条件时束外可能没有电子而成为纯的离子通道，这种状态对微波器件有重要的价值。
