Simulative results show that the electron beam can be transported in the unmagnetized plasma-filled for two reasons. The first, the plasma neutralizes the majority of the space charge forces within the beam. The second, radial electric field generated by electron beam interaction with the plasma leads the beam to converge along axis. By PIC simulation, we find that atomic mass of the background ion effects on the Characteristics of the plasma-filled devices.

非磁化等离子体填充的RBWO-FEL的模拟表明只有在一较窄的背景等离子体密度范围内，电子注才能良好传输，产生泵波及激光功率输出，并都存在有峰值功率点，同实验观测到的结果完全吻合；该范围内，电子注的传输是由于背景离子中和了注中径向发散空间电荷力及注在等离子体中产生的径向的电场使注在轴向汇聚。
