Mean energy of electrons in the oxygen discharge plasma

Czechoslovak Journal of Physics B Aims and scope

Abstract

The mean energy of electrons in the homogeneous form of the positive column in an oxygen discharge is determined. The mean energy of electrons is calculated from double-probe characteristics under the assumption of a Druyvesteyn distribution using volt-equivalents of the electron “temperature”. The relation between the mean energy of electrons andE/p is compared with the theoretical results of another author. As a result of this comparison it can be concluded that for some discharge conditions the energy distribution of electrons is very close to a Druyvesteynian. We also analyze the influence of the negative ions on the double-probe characteristics.
