Abstract
A new device based on very short pulsed discharges, generating plasmas balls and plumes over very long distances (up to several meters). These plasma balls travel in a dielectric guide at the end of which there is generation of an apparent plasma plume like zone, with a shape and intensity dependent on the discharge repetition rate. A secondary mixture plasma can be produced close to a given surface by adding other gas fluxes in the main gas stream. The plasma balls can be generated in gases at a repetition rate in the range from single shot to multi-kilohertz.
