Electrical behavior of an excimer lamp excited by an Argon-based dielectric barrier discharge

UV light sources are becoming more important in the biomedical field, among these sources; we find lamps excited by dielectric barrier discharge (DBD). The work consists on electrical study of an argon-filled DBD plane excimer lamp powered by a sinusoidal-shaped voltage source. The aim is to obtain a uniform light source with better efficiency. In this work, we used a simulation model where the DBD was taken under fixed temperature condition (400K), the electrodes are circular in shape with a radius of 5cm, the gap is 1mm, the applied voltage varies from 1-5KV and the frequency from 10 to 70 KHz and the pressure from 100-700 Torr. A kinetic and electrical study have been made, the kinetic diagram as well as the results of the current intensity and the total capacitive power deposition will be presented.
