Abstract

Two types of cylindrical non-thermal dielectric barrier discharge plasma sources working at atmospheric pressure have been investigated and the electrical and optical characteristics were determined. The configurations compared are ring-and-rod and double-ring. At 30. kHz frequency and 62. W fixed input power, the electrical characteristics: V-I and V-Q Lissajous curves were measured. The capacitances, energies dissipated, and powers consumed for plasma generation have been quantified. Light emission characteristics of the two configurations were also measured at the main discharge region between the electrodes as well as at the afterglow plasma region. The propagation speed of ionization front of afterglow plasma has been estimated to be 0.5-1.3. cm/μs in this experiment.
