Space Charged SF6 Switching Studies

Abstract

Because intense heating limits spark gap repetition rates, interest in diffuse discharge switching has been increasing. Experimental apparatus to determine possible diffuse discharge applications of space charged SF6 gas is described as are the resulting high field electrical transport properties. In particular, prebreakdown current/voltage characteristics are reported for reduced fields E/N approximately 10 (exp -15) v/cm2 and pre breakdown ion currents 100 microamperes. The effect of externally induced photo detachment is also investigated with emphasis on system switching parameters.
