介绍了一种基于行波磁场加速器的新型双级推进系统。在初级电离源中产生的等离子体被注入第二级，在第二级中，等离子体通过行进磁场被加速。通过粒子-细胞模型的分析强调了电子作为加速载体的作用：磁场直接作用于电子，在磁前沿产生空间电荷，产生的电场也加速了离子。该系统的原型已建成使用传输线配置的初步实验研究。微波源被用作初级电离级。实验装置包括电流探头、磁场探头和飞行时间探头。
This paper describes a new dual-stage propulsion system based on a traveling magnetic field accelerator. The plasma produced in a primary ionization source is injected into the second stage where it is accelerated by means of a traveling magnetic field. An analysis through a particle-in-cell model highlights the role of electrons as carriers of the acceleration: the magnetic field directly acts on electrons creating a space charge at the magnetic front, where the resulting electric field also accelerates the ions. A prototype of the system has been built using a transmission line configuration for a preliminary experimental investigation. A microwave source is used as the primary ionization stage. The experimental setup includes current probes, magnetic field probes and time-of-flight probes.
