This paper reports the electrical behaviors of atmospheric pressure plasma reactor with Dielectric Barrier Discharge (DBD) in air medium. The DBD discharge was generated in air at atmospheric pressure using Disc Electrode Geometry (DEG) reactor powered by ac voltage (0-7kV) at a frequency of 24kHz. The glass plates of thickness 1.0mm and 3.0mm were used as dielectric. The current-voltage characteristics were studied for two air gap of 2.0mm and 3.0mm by varying the applied voltages. The numbers of filamentary micro discharges were found as increased in each half cycle with increase in power. The observations of Lissajous figure of applied voltage versus electric current was used for measuring energy deposited by discharge and also compared with calculated value. Lissajous figures clearly show that the energy deposited by discharge was dependent on applied voltage. The electron density of discharge was measured by power balance method. Electron density was found in the order of 1017 per cubic meter.

AbstractThe decaying plasma that is produced by the dielectric barrier discharge (DBD) in helium across a cylindrical tube at a pressure of helium 1–40 Тorr has been spectroscopically investigated. The radical difference between the nature of the barrier discharge afterglow and longitudinal pulse discharge afterglow at the same plasma electron density has been demonstrated. It has been shown that this effect is due to the abnormally low density of metastable He(2^1 S _0, ^3 S _1) atoms in the plasma that is produced by DBD. In such an experiment, it is possible to observe a purely recombination afterglow that is free of processes involving metastable atoms, which is fundamentally important for solving the problem of helium afterglow.

A homogeneous dielectric barrier discharge (DBD) was produced in air with a mixture with argon by applying high voltage A.C. source of potential difference (0-20) kV and frequency (20-50) kHz across two parallel disc electrodes with glass as dielectric barrier. In this paper, the determination of electron density in glow mode based on power balanced method is presented. Significant effects in electron density were found with the variation applied voltage.The Himalayan Physics Vol. 4, No. 4, 2013 Page: 10-13 Uploaded date: 12/22/2013
