AbstractRecently we proposed a method to determine the gas temperature using the van der Waals broadening of atomic spectral lines for atmospheric pressure Ar-He plasma. Here our investigations are continued by studying the influence of Ar*-Ne interactions in order to enlarge the applicability of the proposed method for the determination of gas temperature in argon - neon mixtures. The Ar I 425.9 nm line is found to be suitable for the gas temperature determination.

The goal of the present work was the investigation of the possibility to use intensity distribution of the Q-branch lines of the hydrogen Fulcher-α diagonal band (d3Πu−→a3∑g+ electronic transition; Q-branch with v=v′=2) to determine the temperature of hydrogen containing high-frequency electrodeless lamps (HFEDLs). The values of the rotational temperatures have been obtained from the relative intensity distributions for hydrogen-helium and hydrogen-argon HFEDLs depending on the applied current. The results have been compared with the method of temperature derivation from Doppler profiles of He 667.8 nm and Ar 772.4 nm lines. The results of both methods are in good agreement, showing that the method of gas temperature determination from the intensity distribution in the hydrogen Fulcher-α (2-2)Q band can be used for the hydrogen containing HFEDLs. It was observed that the admixture of 10% hydrogen in the argon HFEDLs significantly reduces the gas temperature.
