Abstract

The paper presents the results of experiments for studying the dynamics and internal structure of an axial plasma jet at the PF-3 facility. Measurements of the azimuthal distribution of the toroidal magnetic field \({{B}_{\varphi }}(\varphi )\) were carried out. A joint analysis of the experimental base of the obtained distributions \({{B}_{\varphi }}(\varphi )\) and the optical detection data of the plasma glow from the plasma flow revealed two types of motion observed simultaneously: the azimuthal rotation of individual parts of the plasma flow, as well as the displacement of the central current’s region relative to the axis of the facility’s transit chamber. The angular velocity of plasma rotation is estimated from the data of magnetic measurements and high-speed optical photographic recording. Some features of the current in the head and tail of the flow are revealed. It is shown that the results obtained are consistent with the MHD theory of jets ejected from young stars.

在研究PF-3设施中轴流射流的方位角结构时，对从年轻恒星物体射出的射流旋转进行实验室建模的方法

摘要

本文介绍了在PF-3设施上研究轴向等离子体射流的动力学和内部结构的实验结果。进行了环形磁场\（{{B} _ {\ varphi}}（\ varphi）\）的方位角分布的测量。对获得的分布\（{{B} _ {\ varphi}}（\ varphi）\）的实验基础进行联合分析来自等离子流的等离子辉光的光学检测数据揭示了同时观察到的两种类型的运动：等离子流各个部分的方位角旋转，以及中心电流区域相对于设施传输轴的位移室。从磁测量和高速光学照相记录的数据估计等离子体旋转的角速度。揭示了流的头部和尾部中电流的一些特征。结果表明，所获得的结果与从年轻恒星喷射的MHD理论相一致。
