Abstract

A system of microwave diagnostics of non-stationary atmospheric-pressure plasma jets based on microwave cavity resonance spectroscopy has been developed. The developed system consists of a spectrum analyzer and a cylindrical microwave cavity resonator, in which a TEIII transverse electric eigenmode was excited. The resonator was excited and the signal was recorded using two small linear antennas placed closer to the bases of the cylindrical resonator. The time dependences of the average volume conductivity of plasma jets of helium and argon dielectric barrier discharges were measured. The discharge was powered from a 160 kHz alternating voltage source with both continuous generation and an interrupter. The use of the interrupter in the power supply allowed to estimate the relaxation time of the plasma jets.
