Plasma Parameters of a Spherically Stratified Gas Discharge

摘要

Basic parameters of spherically stratified gas-discharge plasma are studied. Radial distributions ofthe electron concentration and temperature are measured by the method of an electric probe. It is shown thatthe electron concentration and temperature in an unstratified discharge monotonically decrease from the anodeto cathode, while, in a stratified one, they have discontinuities on the strata borders, which can be caused by theappearance of double layers in such a discharge.
