A Novel Room-Temperature Air Plasma Jet Array Driven by DC Power Supply

In this paper, we report on a novel roomtemperature air plasma jet array with a large cross section. There is no risk of glow-to-arc transitions. It is demonstrated that the air plasma plumes could merge together and produce a stable homogeneous glow. One hundred shots integrated photograph on dynamic of the air discharge is taken. The photograph reveals that the air plasma appears homogeneous.
