Radio-Frequency Glow Discharges of Different Gases Using Bare Metallic Electrodes at Atmospheric Pressure

The images of the atmospheric-pressure glow discharges driven by the radio-frequency power supply using He, Ar, N
₂
, O
₂
, air, or their mixture as the primary plasma-working gas are presented in this paper. The plasma jet, produced using the planar-type plasma generator behaving like a "brush", is useful for the effective treatment of different materials exposed to the plasma jet.
