摘要

感应脉冲等离子体推力通过脉冲感应电磁场电离和加速等离子体产生推力。放电区内磁场的空间分布既影响施加在等离子体上的洛伦兹力，也影响等离子体与电路之间的电磁耦合。建立了具有高重复性的感应脉冲等离子体推进器实验原型和具有低积分误差的三维瞬态磁场测量系统。通过重复脉冲放电的扫描测量，获得了等离子体中与时间相关的磁场空间分布。结合高速摄影和电参数测量的结果，讨论了等离子体结构演变与磁场穿透之间的关系。

Experimental study on the time-dependent spatial distribution of the three-dimensional magnetic field in an inductive pulsed plasma thruster

Inductive pulsed plasma thrust generates thrust by ionizing and accelerating plasma through pulsed inductive electromagnetic field. The spatial distribution of the magnetic field within the discharge region influences both the Lorentz force exerted on plasma and the electromagnetic coupling between plasma and circuit. An experimental prototype of inductive pulsed plasma thruster with high repeatability and a three-dimensional transient magnetic field measurement system with low integration error are established. Time-dependent spatial distribution of the magnetic field in the plasma is obtained by scanning measurement employing repeated pulse discharges. Combined with the results of high-speed photographing and electrical parameter measurements, the relationship between the evolution of plasma structure and the magnetic field penetration is discussed.
