Electrical and Optical Characterization of Dielectric Barrier Discharge Produced in Atmospheric Air

Abstract

This paper reports the results concerning the production of Dielectric Barrier Discharge (DBD) at atmospheric pressure air and its electrical and optical characterization. The discharge was produced by applying high voltage AC source of frequency (10-30) kHz and potential difference of (0-20) kV across the electrodes. The discharge was characterized by measuring current and voltage with a high frequency digital oscilloscope. The optical characterization was made by taking the spectrums of discharge by optical emission spectrometer. The optical spectra in the range of 200 nm to 450 nm have been analyzed in order to estimate the electron temperature by intensity ratio method. Results showed that the electron temperature is about 1.9 eV.

Development of atmospheric pressure air dielectric barrier glow discharge in large gaps through modulation of pulsed power supply upon AC

“…In general, the purpose of placing a barrier is to limit the current development in order to control and suppress the ionization avalanche and sudden discharges. Considerations of the barrier, including the type of barrier material (dielectric 22 , resistive 23 , or ferroelectric 18 ), and thickness, are the most important factors in creating a uniform glow discharge. Although many attempts have resulted in the generation of glow discharge in air at atmospheric pressure only in small gaps, the generation of glow discharge in large gaps has been reported in some papers.…”

Influence of Distance and Argon Flow rate on Pseudomonas aeruginosa Bacteria Exposed to Non thermal Plasma at Atmospheric Pressure

“…Free radicals formed during plasma generation are described as atoms or molecules with non-marital electrons or contains an open casing. In addition, some ultraviolet radiation is generated when plasma is formed [6,7,8].…”
