Abstract
An apparatus for efficiently generating ozone in dry air or in oxygen at about 1 bar pressure. The apparatus generates a uniform cold plasma having no arcs or localized discharges that fills the entire generator volume. Electrical pulses having a peak voltage of approximately 20 kV, pulse width of approximately 20-ns FWHM, and repetition rate of approximately 10 kHz drive the generator. Short pulses apply voltage to the generator on a short time scale compared to the time required to form an arc-like discharge, and at an electric field strength many times over DC breakdown, which is not achievable with long electrical pulse widths. The generator is optimized for cool, UV-free operation. Dimensions of the generator are adjusted to optimize production of ozone by tailoring the distribution function of the electrons in the cold plasma. Overall efficiency of the generator approaches 50% of the theoretical quantum efficiency of generating ozone.
