ABSTRACT
An atmospheric pressure plasma jet source driven by pulsed wave of several tens of kilohertz and by sinusoidal wave was designed and characterized. A newly designed jet consists of a sharpened tungsten pin electrode covered with a cone type Teflon layer confined in a Pyrex tube. This structure provides an efficient ignition since the electric field is concentrated on the end of electrode. Using the electrical and optical characterization, the properties of plasma bullet were explored. For the Ar plasma jet driven by a pulsed wave at low duty cycles, the volume, the speed, and the luminosity of the plasma bullet became larger, and the striation behavior was observed.

    Effects of the metal plasma jet emitted from the cathode spot of a vacuum arc (or a unipolar arc) on the surrounding electric field variation are investigated. It is shown, using a 2-D magnetogasdynamical model, that the cooling of the expanding metal plasma over the cathode surface leads to a...
