Granted: 2021-10-18
Abstract: FIELD: plasma technology.  
     SUBSTANCE: invention relates to plasma technology, to the section of methods for controlling plasma. The method is implemented by changing the potential of the electric field in a gas medium, using the point creation of a relief of micron sizes on the surface of a solid dielectric for the accumulation of surface charges, forming areas of increased tension and additional ionization foci in the discharge gap. This makes it possible to deform the electric field in the vicinity of the relief without coming into contact with the plasma. Such a non-contact electrical effect of the dielectric reduces the average breakdown voltage of the gas, increasing its ionization and directing plasma flows.  
     EFFECT: possibility of improving the accuracy of plasma flow control.
