Abstract
Radial profiles of gas temperature, electron temperature, and electron density were measured in a free-burning atmospheric-pressure argon ar c-discharge plasma using line-shape analysis of scattered laser light. This method yields gas temperature, electron temperature, and electro n density directly, with no reliance on the assumption of local thermo dynamic equilibrium (LTE). Our results show a significant departure fr om LTE in the center of the discharge, contrary to expectations.
