| Outline of Final Research Achievements |
Towards the high density and high yield production of hydroxyl radicals in atmospheric pressure plasma, which is effective for sterilization and decomposition of molecules, a control method of the accumulated electrical charge on the dielectric surface has been developed with an AC high voltage biased nanosecond pulse dielectric barrier discharge, whose impact on the productions of the hydroxyl radical, ozone, and nitric oxides have been experimentally investigated. In this study, the control of the electrical charge on the dielectric surface with the nanosecond pulse appears to enhance the pulse discharge current and the peak to peak electrical charge in AC cycle. In addition, both enhancement effects on the current and electrical charge due to the nanosecond pulse superposition are found to be well correlated with the produced ozone and dinitrogen monoxide densities.
