Possible Mechanisms for Electric-Field-Free Gas Breakdown

Abstract:

It was reported in the late 1960s 1 that gas breakdown occurs during explosive and electrical operation of magnetic flux compressor generators FCGs. Recently 2,3, we reported on experimental evidence of the formation of plasma and its propagation in the gas within the FCG with no electric field in the system. We named this phenomenon electric-field-free gas breakdown. In this paper, we discuss possible mechanisms for this type of gas breakdown. The first mechanism is related to the ionization of the gas by a sequence of shock processes caused by an explosively expanding metallic armature within an FCG. The second mechanism is related to the ejection of high-speed particles from the explosively shocked metallic surface of an FCG armature.
