Abstract

Switching of a short vacuum gap with an auxiliary discharge over the surface of a dielectric has been studied via high-speed recording of images of discharge plasma radiating in the optical spectral range. Based on the analysis of experimental data, we surmise that the cathode spot and cathode flame radiation play an important role in the formation of the current channel in the discharge.
