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.
