Effect of Electrodes types on the Properties of the Dielectric Barrier Discharge Plasma

Abstract

In this research, the dielectric barrier discharge (DBD) plasma system was
designed. This design consists of two electrodes with a diameter (5 cm)
surrounding by Teflon with the top thickness (2 cm) and the bottom thickness is
(2.9 cm). The glass as a dielectric barrier with (2 mm) in thickness was used.
Non-thermal DBD Plasma was produced by applying (16 kV) AC voltage
source between the two electrodes and a glass plate as a dielectric barrier. The
effect of electrodes type on the properties of produced DBD Plasma was studied;
Copper and Aluminum electrode was used for this purpose. Plasma parameters
were calculated by analysis Plasma spectrum measured using optical emission
spectroscopy and using Boltzmann plot method. Electron temperature (Te) found
to be (4.46 eV) and (4.18 eV) for Copper and Aluminum respectively.
Keywords: DBD Plasma, Non-thermal plasma, Boltzmann plot.
