Abstract

Two-temperature collisional-radiative model of surface-wave sustained discharge at atmospheric pressure in a capillary tube is presented. Division of microwave power within the discharge is analysed. Calculations are made for atmospheric pressure argon plasma created inside a quartz tube with and without a liquid cooling coat and a shielding grid. Wave attenuation characteristics and axial distributions of density of dissipated power are presented. The predicted dependence of discharge length on the total flux of wave power is compared with the experimental values..
