Abstract
Observations of atmospheric pressure DBD plasma were conducted through the transparent electrode in Air, Argon, Helium, Nitrogen and Oxygen gasses at 1 and 3 standard liters per minute (s1pm) flow rates through the discharge gap, utilizing three types of excitation waveforms. Three phenomena were observed: (1) plasma filaments travel with the gas at the same speed as the gas for some but not all gases; (2) propagation of excitation is observed in Nitrogen plasma and the filament motion has no directional preference with gas flow direction; and (3) Oxygen, Nitrogen and Helium plasmas were observed to be rather uniform at least over longer time periods.
