摘要

摘要利用磁探针和电探针研究了外部轴向磁场对磁等离子体压缩机（MPC）产生的夹持等离子体流的影响。在存在外部磁场的情况下，温度测量显示等离子体流核心附近有两组温度不同的电子。外部磁场导致等离子体流中的电流、电子温度显著增加，并首次在MPC中观察到电流片状结构的形成。

Structure and local parameters of self-compressed plasma streams in external magnetic field

Abstract The influence of the external axial magnetic field on pinching plasma flows generated by a magnetoplasma compressor (MPC) has been studied using magnetic and electric probes. In the presence of an external magnetic field, temperature measurements show two groups of electrons with different temperatures near the plasma stream core. The external magnetic field leads to a noticeable increase in the electric current in the plasma stream, electron temperature, and the formation of the current-sheet-like structure observed in the MPC for the first time.
