Abstract

The formation of red plasma diffuse jets (PDJs) initiated by a capacitive discharge in air at pressures of 0.1–10 Torr is studied. Data on the dimensions and properties of plasma diffuse jets including counter-propagating ones with different and identical front polarities are obtained in a pulse-periodic discharge mode in a 15-cm-diameter tube. Photographs of the discharge glow in various modes are presented. It is confirmed that the emission of counter-propagating PDJs is suppressed at the same polarity of voltage pulses. It is shown that during a collision of unipolar PDGs formed from two generators the brightness of the discharge plasma between the ring electrodes increases.

低压空气中大直径等离子扩散射流的形成
摘要 研究了在压力为 0.1-10 托的空气中由电容放电引发的红色等离子体扩散射流(PDJ)的形成。在一个直径为 15 厘米的管子中,以脉冲周期放电模式获得了等离子体漫射射流的尺寸和特性数据,包括具有不同和相同前极性的反向漫射射流。照片显示了各种模式下的放电辉光。结果证实,在相同极性的电压脉冲下,逆向推进的 PDJ 的发射受到抑制。研究表明,在两个发生器形成的单极 PDG 碰撞过程中,环形电极之间的放电等离子体亮度增加。

期刊介绍: Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
