Generation of Large Volume Atmospheric Pressure Air Plasma

Atmospheric pressure large volume air plasma was generated by applying 100 ns, 1-kHz high voltage pulse between two parallel electrodes separated by 48-mm gap. The high voltage power electrode has uniformly distributed pens and ground electrode shaped as a flat disc. Glow discharge ignition is initi...

Zusammenfassung:Atmospheric pressure large volume air plasma was generated by applying 100 ns, 1-kHz high voltage pulse between two parallel electrodes separated by 48-mm gap. The high voltage power electrode has uniformly distributed pens and ground electrode shaped as a flat disc. Glow discharge ignition is initialized at the outer pens to form luminousness circle. By applying higher voltage, the glow expands to ignite the internal pens and to fill the gap between the two electrodes. Each pen forms glow discharge plasma with the ground electrode. The increase in voltage or frequency enhances the plasma intensity and homogeneity. The generated plasma showed efficiency against the fruit borne fungi of grapes.
