论文摘要

在径向内爆阶段和等离子体焦点的捏阶段存在轴向磁场的直接实验证据都提出了许多基本重要性的问题。其中最基本的是其存在的事实,从传统的血浆物理学看来,这是难以理解的。已知血浆在径向内爆相中具有对称轴。轴向磁场相对于轴具有定义的极性。由于磁流失动力学的方程是通过翻转轴向坐标的符号而没有改变的,因此轴向磁场的极性必须来自初始条件。确切的初始条件确定轴向磁场的极性尚不清楚。需要更多数据来指导这个问题的理论发展。轴向磁场测量的常规技术(例如磁探针和法拉第旋转测量)存在一些技术问题。理论和实验困难的综合作用是,研究人员避免了与轴对称等离子体中轴向磁场相关的研究,而支持更多面向结果的项目,但不幸的是,与轴向对称等离子体中轴向磁场存在有关的问题仍然未分辨。为了促进与血浆焦点和其他等离子体中轴向对称性相关的问题有关的研究,本文引入了一种新技术,该技术通过重新定义测量的目标和范围来避免测量的技术困难。该论文以教程形式撰写,以使年轻研究人员刚刚开始研究生涯的利益,因此不会在常规期刊上发表。鼓励同伴科学家和年轻研究人员直接与作者联系。

Direct experimental evidence for the existence of axial magnetic field both in the radial implosion phase and the pinch phase of a plasma focus has raised many questions of fundamental importance. The most fundamental of these is the fact of its existence, which is incomprehensible in terms of a conventional view of plasma physics. The plasma is known to have an axis of symmetry in the radial implosion phase. The axial magnetic field has a defined polarity with respect to the axis. Since the equations of magnetohydrodynamics are unchanged by flipping the sign of the axial coordinate, the polarity of the axial magnetic field must arise from the initial conditions. Exactly how the initial conditions determine the polarity of the axial magnetic field is not clear. More data are needed to guide theoretical developments of this question. There are several technical problems with the conventional techniques of axial magnetic field measurement such as magnetic probes and Faraday rotation measurement. The combined effect of theoretical and experimental difficulties is that researchers avoid research related to the axial magnetic field in axisymmetric plasmas in favour of more result-oriented projects, with the unfortunate consequence that questions related to the presence of axial magnetic field in axially symmetric plasmas remain unresolved. In order to promote research related to the questions related to the axial magnetic field in the plasma focus and other plasmas with an axial symmetry, this paper introduces a new technique that skirts the technical difficulties of measurement by redefining the objectives and scope of measurement. The paper is written in a tutorial format for the benefit of young researchers just beginning their research career and hence will not be published in regular journals. Peer scientists and young researchers are encouraged to contact the author directly.
