Comparison of methods of self-absorption and effective branching fractions for metastable densities determination in surface-wave neon plasma

Popis výsledku v původním jazyce

A novel type of surface-wave sustained microwave discharge in neon at low pressure was studied by optical emission spectroscopy. The spectra of neon from transitions 2p5 3p to 2p5 3s were measured in axial and azimuthal directions and analysed for an effect of self-absorption in order to determine the densities of neon metastable states 1s3 and 1s5 (in Paschen notation) for different pressures. The methods of self-absorption and branching fractions were investigated and obtained results were compared. Supporting "white light" absorption experiments with external LED light source were performed in order to prove the non-absorption character in azimuthal direction.
