Název v původním jazyce

Spectroscopic investigation of multiple Boltzmann distributions of various atomic and ionic states in an expanding H2O-Ar dc arc jet

Popis výsledku v původním jazyce

Předneseno na:12th European Plasma Conference (12th High-Tech Plasma Processes conference, HTPP-12),Bologna,IT,24.-29.06.2012, PS1.11 Population distributions of argon atomic and ionic excited states in the supersonic part of a plasma jet expanding fromthe H2O-Ar dc arc torch into a chamber maintained at a pressure of 10 kPa have been studied by optical emission spectroscopy. The excitation temperatures are obtained from ArI (13.1-15.3 eV) and ArII Boltzmann (19.2-22.5 eV) diagrams. The ionization temperature is obtained from the intensity ratio of argon ionic and atomic lines, using electron number density calculated from the Stark broadening of hydrogen Hß line and Saha equation. A systematic difference in the total excitation temperature between both argon systems is found, with the ionic excitation temperature being significantly higher and close to the ionization temperature. The Boltzmann plots also reveal that the population distribution within a given electronic configuration
