Abstract.

The electron density is measured in an argon-CO2 thermal plasma by optical emission spectroscopy. Electron density is deduced from the Stark broadening of the argon line and hydrogen (H\(_{\alpha}\)) line. Different theories are used and compared. The effect of CO2 molecule upon this plasma is studied as a function of the Ar-CO2 mixture composition and discharge current. The electron density is ranging from 3 x 1021 m-3 to 5.6 x 1022 m-3. The influence of the arc confinement is studied and the electron density gradients are evaluated. Departure from local thermal equilibrium is also discussed.
