摘要

本研究探讨了横向磁场对压力为 30 托的氦气中高压脉冲放电的影响。研究提出了一个描述横向弱磁场（B = 0.4 T）中氦气高压脉冲放电的简单二维流体模型，该模型使用经验关系来解释磁场。使用经验关系计算有效磁场的结果与实验结果非常吻合。此外，还研究了磁场存在时的放电发展动态。在压力为 30 托的氦气中，磁场对气体放电发展动力学没有明显影响。

Transverse magnetic field effects on the high-voltage pulsed discharge plasma in helium

This study investigates the effect of a transverse magnetic field on high-voltage pulsed discharge in helium at a pressure of 30 Torr. A simple two-dimensional fluid model that describes the high-voltage pulsed discharge in helium in a transverse weak magnetic field (B = 0.4 T) is presented, which uses an empirical relation to account for the magnetic field. The results of using the empirical relation for the effective field agree well with the experimental results. The dynamics of discharge development in the presence of the magnetic field is also investigated. The magnetic field does not significantly affect the gas-discharge development dynamics in helium at a pressure of 30 Torr.

期刊介绍： JPP aspires to be the intellectual home of those who think of plasma physics as a fundamental discipline. The journal focuses on publishing research on laboratory plasmas (including magnetically confined and inertial fusion plasmas), space physics and plasma astrophysics that takes advantage of the rapid ongoing progress in instrumentation and computing to advance fundamental understanding of multiscale plasma physics. The Journal welcomes submissions of analytical, numerical, observational and experimental work: both original research and tutorial- or review-style papers, as well as proposals for its Lecture Notes series.
