Control of the Development Rate of the Incomplete Stage of the Discharge Sliding on the Dielectric Surface

The possibility of controlling the development rate of the incomplete staged of the discharge sliding over a solid dielectric surface is experimentally shown. Depending on the gas pressure and power supply voltage, the development rate of the incomplete stage of the discharge in air sliding over the solid dielectric surface is determined. It is shown that the discharge development rate varies from 1.4 × 106 to 7.8 × 106 cm/s in the pressure range from 10 to 60 Torr voltage from 4 to 12 kV. Emission of the second positive system of nitrogen dominates in the emission spectrum of the incomplete sliding discharge.
