The electromagnetic field characteristics of the high-frequency torch discharge

Research output: Contribution to journalArticle

Abstract

The axial distribution measurements of the electric field harmonic component amplitudes of the high-frequency torch discharge operating in air, argon and helium were carried out. The truth of the high frequency torch discharge model, considering reflection of the electromagnetic wave at the end of the discharge channel, was examined on basis of this experimental data. The absence of coefficient variation of electromagnetic field damping due to the frequency in case of flare discharge ignition in air or argon was found. The ion and electron plasma frequencies estimation of the high-frequency torch discharge operating in various gases was carried out. The suggestion about parametric interaction of the external electromagnetic field with the own oscillations of the discharge plasma was formed.
