磁力矩器对星外等离子体分布影响分析

文章通过计算某型号磁力矩器工作时产生的磁场，分析了等离子体在磁力矩器磁场中的运动状态，计算了电子在磁力矩器周围的密度分布。结果显示:在磁力矩器工作时，周围电子密度将增大，最大可为正常密度的10倍。密度增大的区域尺寸在轴向上略大于磁力矩器的长度，越靠近磁力矩器的两端电子密度越小，形成一个“凹陷”；径向上主要在半径小于4 m的范围内。在此区域应避免摆放对带电粒子敏感的部组件。

The influence of magnetorquer on the space plasma

This paper studies the influence of magnetorquer on the space plasma and presents calculations of the motion states of plasma in the magnetic field produced by the magnetorquer in operation, and the electron density distribution around the magnetorquer. The results show that the electron density around the magnetorquer will increase during the operation of the magnetorquer. The axial dimension of the region with increased electron density is a little larger than the length of magnetorquer. In the region, the electron density is 2-5 times higher than the value when the magnetorquer is not in operation and even 10 times in some places.
