METHOD OF PRODUCING PLASMA JET AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC H05H1/24 

FIELD: physics.

SUBSTANCE: spark discharge between two tip electrodes is ignited, one electrode is left under a floating potential, wherein high voltage pulses of a positive polarity voltage with a rising edge of 0.1<τ<10 mcs are fed to the second electrode, ignition of the discharge is carried out between the electrodes installed at an angle of 0<α<160°, forming a plasma jet at the point of maximum curvature of the current channel. The device implementing the method comprises two tip electrodes forming a spark discharge gap, one electrode is free, a high voltage power source, the second electrode located at an angle of 0<<α160° to the first one, is high-voltage and has a positive voltage polarity with a rise front of 0.1<τ<10 mcs, the discharge gap is 5<d<20 mm.

EFFECT: simplifying the design, obtaining plasma jets of atmospheric pressure in air without forced air pumping and reducing the gas flow in media containing mixtures of readily ionizable gases with electronegative gases.
