摘要：

The presented paper focuses on the influence of the gas flow rate on the electric field distribution in the capillary and plume of the helium plasma jet. 30 kHz AC-driven He jet with the coaxial geometry is used in this study. For the fixed amplitude of the applied voltage of 2 kV, electric field strength is measured using Stark polarization spectroscopy for several gas flows in range of 700-2000 SCCM. It was found that the increase of gas flow doesn't change the maximal value of the electric field, but it stretches measured profile in space.
