AbstractNon-thermal atmospheric pressure plasma is new branch and tool in physics .Building generation dielectric barrier discharge (DBD) system at atmospheric pressure and studying of its thermal characterizations. The discharge was produced by applying high voltage (5-25 KV) and frequency (12 kHz). The thermal characterization was done by measuring discharge temperature at different applied voltage and different distances from barrier. The results indicate that the applied voltage and distance between electrodes effect on discharge (increasing or decreasing) according to operation conditions because they affects, as expected, the DBD plasma temperature decreases with the increasing of the dielectric thicknesses which results in the decrease of the discharge voltage across the gap, accordingly, the discharge across gap is also weakened.
