Abstract

This paper presents the results of the experimental investigation of plasma chemical conversion of sulphur hexafluoride initiated by a pulsed electron beam (TEA-500 pulsed electron accelerator) with the following characteristics: 400–450 keV electron energy, 60 ns pulse duration, up to 200 J pulse energy, and 5 cm beam diameter. Experiments were conducted on the effect of the pulsed electron beam on SF₆ and on mixtures of SF₆ with O₂, Ar, or N₂. For the mixture of SF₆ and oxygen, the results indicated chemical reactions involving the formation of a number of products of which one is sulphur, confirming the Wray – Fluorescence Analysis. The plasma chemical conversion of SF₆ initiated by the pulsed electron beam was not detected when SF₆ was mixed with Ar or N₂, suggesting a possible mechanism for the reaction of SF6 in the presence of O₂.
