Abstract

In this work, the results of an experimental study of plasma parameters of a secondary discharge at atmospheric pressure, sustained by a low-power (~ 100 W) rotating gliding discharge in an air stream under conditions of a significant excess of the plasma channel length of the secondary discharge over the length of the self-sustained discharge channel in the range of 1...100, are presented. Plasma parameter determination was carried out using emission spectroscopy of the plasma with the SpecAir program. The assessment of the electric field intensity in the secondary discharge plasma was based on the dependencies between the discharge voltage drop and the length of the discharge current channel.
