Investigation of surface-wave sustained discharge in neon by optical emission spectroscopy and collisional-radiative modelling

Popis výsledku v původním jazyce

The aim of this work is to extend a previously developed method of determination of an electron temperature from optical emission spectra to surface-wave sustained microwave discharges. A surface-wave sustained discharge in coaxial tube structure in neonat low pressure (300?700 Pa) was studied by an optical emission spectroscopy. The spectra of the discharge were analyzed first with self-absorption methods in order to determine the densities of neon metastable states 1s3 and 1s5. The optical spectra measured in absorption-free direction were then analyzed with a 0D collisional-radiative model for neon discharge in order to determine the electron temperature and the reduced electric field strength in the discharge. Two types of the electron distribution function were used in the calculations ? the Maxwellian EDF and the solution of the Boltzmann kinetic equation. The neon metastable densities determined from the self-absorption method depended on the gas pressure ranging 0.10?0.46 x 10
