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.
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.
