Abstract :
The spatiotemporal development of a pulsed dielectric barrier discharge, which presents a secondary discharge, is investigated. The study focuses on space-time distribution of the representatives´ excited species using a high-speed camera technique combined with bandpass filters. The results demonstrate that the breakdown starts at the anode. The excitation mechanism of various species is analyzed.
