This paper reports on first experimental study of a self-sustained volume discharge (SSVD) in c-C₄F₈. The discharge voltage and current oscillograms are taken over a wide range of gas pressures. How and why this discharge radically differs from that in other strongly electronegative gases is considered in terms of the theory of the vibrational relaxation in polyatomic molecules. For the first time an SSVD in c-C₄F₈ preheated by CO₂-laser radiation has been investigated. The unusual behavior and temperature-dependent characteristics of this discharge are revealed. There is much discussion on the peculiarities of an SSVD in a preirradiated c-C₄F₈. To refine the static limiting field in c-C₄F₈ the static dielectric strength of c-C₄F₈ is measured on changing the gas pressure by nearly two orders of magnitude.
