Then the ion channel performance is simulated and its oscillatory property is verified. Finally the nonlinear properties of the device are emulated. Several new results and ideals are obtained through the study on some issues in the drift and. slow wave structure region in PASOTRON in this paper. First, from the study of electron beam focussing and transmission properties in plasma, we can conclude that the famous BANNETT self pinch is only a short segment on the transmission curve, and the real transmission pattern is wavelike. This, to some extent, can extend our knowledge to the magnetic self pinch Second, generally it is thought the plasma density should be great to get high power output in plasma microwave devices, however our study shows that after other conditions are settled, there exists a optimum filling density. Third, the function of plasma used to be equivalent to a dielectric tensor, however our study shows that after introducing ion channel the plasma a electrons distributed and even the pure channel can be formed. This, to some extent, leads to the dielectric constant meaningless.
本文通过对无磁场等离子体返波振荡器的漂移区及互作用区的系统研究，获得了一系列具有创新意义的结论：首先，从对等离子体环境下电子束的聚束传输的研究中得出著名的BANNETT效应只不过是传输曲线上的一段，而真正的传输形态是波浪式向前，从而在一定程度上澄清和拓宽了人们对自箍缩效应的认识；其次，以往人们总是认为在等离子体微波器件中等离子体密度要很大才能获得高的输出，本文的研究表明在无磁场等离子体微波器件中，当其它条件确定后等离子体的密度并非越大越好，而是存在一最佳填充密度；第三，以往人们在研究中总是将等离子体的作用归结为一介电常数，本文在引入离子通道后说明在注入电子束后，等离子体电子存在分布，且常常会形成纯的离子通道，使介电常数的概念在一定程度上失去意义。
