Název v původním jazyce
Determination of metastable densities in surface-wave neon plasma by self-absorption method
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 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. Homogeneous and axially dependent spatial intensity profiles were assumed in the calculations. Supporting white light absorption experiments with external LED light source were performed in order toprove the non-absorption character in azimuthal direction. The determined metastable densities depended on gas pressure ranging 0.10 - 0.46 x 10^10 cm-3 and 3.3 - 4.3 x 10^10 cm-3 for 1s3 and 1s5 state, respectively. A large influence of line-pair selection and column inhomogeneity on the resulting values was observed.
