Investigation of microwave energy distribution character in a resonator type plasmatron

Abstract

An investigation of microwave energy distribution character in a plasma of microwave discharge inside a plasmatron based on a rectangular resonator has been carried out. The experiments were done applying the "active probe" method. Microwave discharge was excited in the air and oxygen.

The readings of the "active probe" and data on the local electric conductivity of plasma obtained using electrical probes have been compared.
