Abstract: Atmospheric pressure plasma jet can protrude some 5.0 cm into air. It holdspromise for multivarious innovative applications, but its formation mechanismremains unsettled. We show that the plasma jet is essentially a streamer coronatotally independent of, but obscured by, dielectric barrier discharge.Consequently, the jets can be equally successfully generated even with onesingle bare metal electrode attached to the tube orifice, both downstream andupstream simultaneously, and at a significantly reduced voltage. These resultswill help understand the underlying physics and facilitate a safer and moreflexible implementation of this marvelous plasma source.
