One-Atmosphere Uniform Glow Discharge Plasma as Another Modification of APG

One-Atmosphere Uniform Glow Discharge Plasma as Another Modification of APG 

The discharge transition from filamentary to diffuse mode in atmospheric air has been analyzed (Jozef Sherman, 2005) in the system shown in Fig. 4-100. The transition can lead not only to the dififirse mode but also into another non-homogeneous mode where the filaments are more numerous and less intense. 

Not only volumetric but also surface conductivity of a dielectric can promote DBD uniformity, if it is in an appropriate range. The memory effect can be suppressed by removing the negative charge spot formed by electrons of a streamer during the half-period of voltage
