Electron density measurement in atmospheric pressure plasma jets: Stark broadening of hydrogenated and non-hydrogenated lines

摘要: Electron density is one of the key parameters in physics a gas discharge. In this contribution application Stark broadening method to determine electron low temperature atmospheric pressure plasma jets discussed. An overview available theoretical calculations hydrogenated and non-hydrogenated atomic lines presented. The difficulty evaluation fine structure splitting lines, which important at density, analysed recommendations on applicability for ionization degree plasmas are given. Different emission line mechanisms under conditions discussed an experimental profile fitting procedure determination suggested. Available data carefully excited over wide range frequencies from dc MW pulsed mode. Finally, given concerning technique estimation typical jets.
