Description

This paper deals with investigations of plasma parameters of electric arc discharge between Cu-Mo composite electrodes in argon flow. The radial profiles of plasma temperature and electron density, obtained by optical emission spectroscopy, were used in calculation of plasma composition in assumption of local thermodynamic equilibrium. Additionally analysis of molybdenum atomic spectral lines for purposes of arc discharge plasma diagnostics was carried out. In result of selection several MoI spectral lines and their oscillator strength are recommended
