Abstract
The spatial distribution of gas temperature in the cylindrical positive column of a low pressure glow discharge has been theoretically investigated. Although the theory has been based on the Elenbaas-Heller equation, here the energy input of neutral particles included in the equation has been given by the elastic collision with electrons. According to this, some fresh and remarkable features never found so far, have been obtained. Concrete calculations have been made in He, Ne, and Ar by making use of the quasineutral theory of the positive column recently presented by the authors, and several characteristics have been produced. These results will be contributed to elucidate the mechanism of positive column in gas discharge media including gas laser plasmas.
