摘要

Time-resolved ICCD images of discharge and plasma bullet formation in a capillary dielectric barrier discharge at atmospheric pressure have been obtained across the whole period in the voltage cycle. The images clearly show that the capillary discharge ignites at the inner edges of both electrodes, when each electrode is working as a cathode, and this leads to the formation of afterglow plasma bullets traveling upstream and downstream.
