Calculation of electron transport data in noble gases

POSTER

Abstract

The features of the energy distribution function of electrons drifting in a rare gas are analyzed. The case of electron drift in He, Ne, Ar, Kr and Xe is considered. The results of calculation of the energy balance of electrons and drift characteristics in an electric field at strengths of 0.1 $<$ E/N $<$ 1000 Td taking into account inelastic collisions are presented. We consider the model of electron-atom collisions, which makes it possible to properly consider the energy balance of electrons, including of inelastic collisions. Based on a numerical experiment, characteristics of electron velocity distribution function and energy characteristics of electron drift in the dc electric field were tabulated. The drift velocities, average electron energies, characteristic Townsend energies, average electron energies resulting in atom excitation and ionization events, the ratio of elastic and inelastic energy loss, and the ionization Townsend coefficient were calculated. Moreover, electron diffusion along and across the electric field was considered and the dependence of diffusivities on the diffusion time was obtained. The presented data can be used to analyze experiments with dusty plasma.
