Investigation on Dielectric Barrier Discharge in Neon at Atmospheric Pressure
摘要
Abstract
In order to have a deep understanding of dielectric barrier discharge（DBD） in neon at atmospheric pressure,the breakdown voltage,the discharge mode and evolution of DBD in a parallel neon gap were investigated by means of electrical measurements and fast photography.Homogenous discharges could be easily produced in 2~8mm gaps in neon and were attributed to glow discharge.Compared to that in helium,the homogenous DBD in neon had a smaller discharge current density and a wider current pulse.The differences between the first breakdown and subsequent steady breakdowns were measured,it was revealed that the first breakdown usually had a higher gap voltage and a later phase,as explained by the seed electrons and penning ionization.High-speed time-resolved photographs of the homogenous discharge in neon were taken using an ICCD camera with an exposure time of 10ns.Side-view photographs showed an evolution from Townsend discharge to glow discharge,which was similar to that observed in helium discharge,while the positive column could hardly be observed in neon at the sub-normal stage of the discharge.The end-view photographs showed a radial development in neon discharge which was also similar to that in helium.关键词
