Patent ID: 8778273

Claim:
A device for emitting a plasma jet at ambient pressure and temperature, comprising: an anode assembly; a cathode assembly; and an electric field generator capable of emitting a plasma jet between the anode assembly and the cathode assembly, wherein: the cathode assembly defines a dielectric space, called the inter-cathode space, extending inside a cathode surface of the cathode assembly, and the inter-cathode space comprises at least one cathode opening which opens to the outside of the inter-cathode space; and the anode assembly comprises an anode extending inside the inter-cathode space, one portion of said anode, called the pointed portion, having a minimum radius of curvature, which extends as far as said at least one cathode opening so as to be capable of spontaneously emitting said plasma jet, the plasma jet being projected spontaneously according to a predetermined orientation towards the outside of the inter-cathode space.
