Abstract

It is established that higher stability of a self-sustained volume discharge (SVD) without pre-ionization in mixtures of SF₆ with hydrocarbons (deuterocarbons) is explained by higher surface density of cathode spots and the corresponding reduction of the current across a spot. It is shown that SVD may occur in mixtures of SF₆ with hydrocarbons (deuterocarbons) without special systems for gas pre- ionization in extremely compact system of electrodes. Wide- aperture non-chain HF (DF) lasers with high radiation energy can be created on this basis. Such laser with the aperture approximately 20 cm provided the generation energy 190 J in the case of HF and 152 J in the case of DF and the electric efficiency 3 and 2.4 %, respectively.
