“…The DBD in volume configuration has been adopted for atmospheric-pressure plasma processing at first for its simple design [3,17,18]. The main drawback of the volume DBD lies in the limited thickness of processed material, as follows from its design.…”

Diffuse Coplanar Surface Barrier Discharge (DCSBD) is a novel type of atmospheric-pressure plasma source developed for high-speed large-area surface plasma treatments. The statistical behavior of microdischarges of DCSBD generated in artificial air atmosphere was studied using time-correlated optical and electrical measurements. Changes in behavior of microdischarges are shown for various electrode gap widths and input voltage amplitudes. They are discussed in the light of correlation of the number of microdischarges and the number of unique microdischarges' paths per discharge event.The 'memory effect' was observed in the behavior of microdischarges and it manifests itself in a significant number of microdischarges reusing the path of microdischarges from previous half-period. Surprisingly this phenomenon was observed even for microdischarges of the same half-period of the discharge, where mechanisms other than charge deposition have to be involved. The phenomenon of discharge paths reuse is most pronounced for wide electrode gap width and/or increased input voltage amplitude.

“…Ozone generation efficiency has been widely studied in laboratory conditions and performance has been reported for systems based on pulsed corona discharges and various dielectric barrier discharges [4][5][6][7][8][9][10][11]. For example, more than 20 years ago, Masuda et al [4] reported a surface continuously AC excited (10 kHz and 10 kV peak-to-peak) dielectric barrier discharge (DBD) ozoniser based on a high-purity alumina ceramic with parallel strip-like discharge electrodes and a grounded water-cooled film-like induction electrode capable of producing ozone concentration as high as 5-10 9 10 4 ppm.…”

The measurements of electro-optical discharge characteristics and concentration of produced ozone were performed to evaluate the efficiency of ozone production in an AC surface dielectric barrier discharge (SDBD) in pure oxygen at atmospheric pressure. The discharge was driven in an amplitude-modulated regime with a driving AC frequency of 1 kHz, variable discharge duty cycle of 0.01-0.8 and oxygen flow rate of 2.5-10 slm. We observed asymmetric SDBD behaviour as evidenced by the variation in the ratio of the O I /O 2 ? emission intensities registered during the positive/negative half-periods and complemented by the transferred charge measurements through the Lissajous figures. We also found a strong dependence of O 3 concentration on the discharge duty cycle. The highest calculated ozone production yield reached 170 g/kWh with a corresponding energy cost of about 10 eV/molecule when combining the lowest inspected duty cycle with the lowest AC high voltage amplitude.

“…Using a surface discharge in oxygen at 10 kHz, best result reported by Masuda et al in pure oxygen was a yield of 170 g/kWh [29] with a high level of ozone production of 5 to 10 %. Pietsch in O 2 and in air respectively, using dielectric barrier discharges [30].…”
