Abstract

An interest to properties of the discharge in gas mixtures with SF₆ is justified by a wide use of such mixtures in the electron and commutation apparatuses and in the pulse discharge HF/DF lasers. Such lasers are considered to be perspective sources of radiation in the 2.4-3.2 μm range of the wave lengths. Experimental studies of the discharge in mixtures Ne/SF₆/C₆H₁₄ [1] and SF₆ - C₂H₆ [1, 2] have shown, that under certain conditions the discharge area extends, and spreads over the whole surface of electrodes. Discharge in the pure SF₆ (P = 78 mBar) [3] was shown to expand in width from ~ 2.5 mm to ~ 3.5 mm. The mechanism of such an expansion till now remains unclear. The present paper is devoted to computer modeling of kinetic processes in non-uniform plasma in the SF₆ gas. The kinetic processes affecting temporal and spatial distribution of the current density in non-uniform plasma are revealed.
