Source of a Volume Plasma Jet Based on a Low-Current Nonstationary Discharge

Abstract

A special type of diffusive discharge (glow discharge) on which a low-current spark discharge is superimposed is created experimentally in a gas flow, in the form of atmospheric pressure plasma jets. The flow of current in the discharge gap is a steady regime of periodical current pulses. A highly efficient portable low-temperature nonequilibrium argon plasma source (the PortPlaSter) is designed on the basis of this glow discharge with superimposed low-current spark discharges.
