从填充等离子体微波管漂移空间电子运动轨迹方程出发，详细阐述了α区和β区电子注的聚束性能，电子围绕平衡半径在α区和β区交替波浪式前进，波纹的周期和幅度与等离子体密度和电子运动速度有关，此外，对弱加速场电子传输性能的研究表明，调节等离子体参数、电压和场强，可实现电子注无磁场聚束传输
Based on the equation of trajectory of electrons filled in the space of plasma tube filled with plasma, the beam bunching performance of electron injection in α region and β region is elaborated. The electron moves forward alternately in α region and β region around the equilibrium radius. The period and amplitude of the ripple Plasma density is related to the velocity of electron movement. In addition, studies on the electron transport properties of weak accelerating fields show that adjusting the plasma parameters, voltage and field strength can achieve electron beam-free magnetic field beamforming
