Investigation of the energy characteristics of a plasma torch with an expanding channel for the output electrode

Abstract

The results of experimental and theoretical investigations of low-temperature plasma generators with an expanding channel of the output electrode are presented. Experimental equipment with a sectioned output electrode has been constructed. The distribution of electric current in the section for different values of the consumption of gas and current is determined.
