Abstract
Device for emitting a plasma jet at ambient pressure and temperature, includes an electric-field generator for generating discharges between an anode assembly and a cathode assembly. The cathode assembly defines an inter-cathode dielectric space that extends inside the cathode assembly and is opposite at least one cathode surface of the cathode assembly, and has at least one cathode opening extending outside the inter-cathode space, the cathode opening being defined by at least one active edge of the cathode surface, the active edge(s) extending in a cathode opening plane. The anode assembly includes at least one pointed portion that is oriented toward the outside of the inter-cathode space and is laterally and deeply placed relative to the cathode opening. The pointed portion extends up to the cathode opening plane, for causing a plasma jet emission that is spontaneously sprayed in a predetermined direction toward the outside of the inter-cathode space.
