On the Space Trajectory and Transmission Properties of Magnetically Self-Focussing Beam

本文给出了充等离子体微波管漂移区电子运动的空间轨迹方程，据电子运动特性沿径向将空间划分为三个区域．利用数值方法分别求解非相对论和相对论条件下的空间轨迹，并详细阐述了注的传输特性，讨论了影响电子注传输质量的因素研究表明，适当选择等离子体填充因子和工作电压可实现磁自聚焦电子注的高效高质量传输．

The equation of electron space trajectory in drifting tube filled with on plasma is given in this paper. The space is divided into three areas; the equation is numerically solved under relativistic and unelativistic condition; the transmission properties are studied and some parameters affecting the transmission properties are discussed in detail. The study shows that efficient transmission of magntically Self-focussing beam can be reached by choosing the plasma filling factor and the voltage.
