“…The microdischarges are imaged by a lens, and recorded by an ICCD camera (Andor iStar). By setting the opening of the ICCD gate to different phases of the applied voltage, it is possible to take images of different discharge events within the high voltage cycle (see [50] for details). To measure the spatio-temporally resolved MD development, the light from the single DBD is guided to a monochromator (Princeton Instrument SP2300) entrance slit.…”

“…A highly sensitive photomultiplier for single photon counting (Hamamatsu H5773/Becker-Hickl PMC-100-04) is equipped at the exit slit of the monochromator. This photomultiplier is part of the multi-dimensional time-correlated single photon counting (TC-SPC, Becker-Hickl SPC 152) set-up [50]. The high-voltage-power source as well as the diagnostic devices are controlled by a trigger signal generated in the TC-SPC system in order to enable the recording of the MD development for different phases within the applied voltage cycle.…”

The development of microdischarges and the inception dynamics of subsequent microdischarges in an electrode arrangement consisting of a metal pin and a hemispherical dielectric-covered electrode, operated in air with a small toluene admixture, is studied. The discharge is operated with sinusoidal high voltage. A gated ICCD camera and a current probe enable the recording of images and current pulses of the single microdischarges, respectively, while the spatio-temporally resolved development is measured with a multidimensional time-correlated single photon counting technique. The overall discharge dynamics changes significantly if a concentration of 35 ppm toluene is added to dry air. A lower high voltage amplitude than in dry air is needed for stable discharge operation. This can be explained by the lower ionization energy of toluene compared to molecular oxygen and nitrogen. The microdischarge development is the same with or without admixture, i.e. a positive (cathode directed) streamer mechanism is observed. Lower mean power is dissipated into the discharge when toluene is admixed. The main effect caused by toluene admixture is the suppression of high-energy microdischarges in case of the cathodic pin half-cycle of the sinusoidal high voltage. The influence on the inception voltage by additional ionization mechanisms and volume memory effects, the consumption of energetic electrons for toluene decomposition reactions, and the modification of the surface by plasma treatment are discussed as possible reasons.

The formation of carbon monoxide, oxygen and ozone in a barrier corona discharge (BCD) operating in pure carbon dioxide (CO2) and binary mixtures of CO2 and argon is studied. The asymmetric electrode configuration of the BCDs allows plasma operation at pressures exceeding 1 atm, up to 6 bar, at moderate high-voltage amplitudes below 15 kV. Charge–voltage plots and an equivalent circuit model are employed to characterize the electrical parameters at different pressures and gas compositions. Depending on these conditions and the voltage amplitude, full or partial coverage of the electrodes with plasma is obtained. The existence of an optimum pressure for power dissipation for each given operation voltage amplitude and gas composition can be confirmed and explained by the equivalent circuit model. Increasing the CO2 concentration in the working gas increases the mean reduced electric field strength E/N while pressure reduces it in the BCD. The CO2 conversion shows a maximum efficiency of about 4% at 1.5 bar for the gas mixture Ar/CO2 = 1:1 and a voltage amplitude of about 10 kV. The calculation of thermodynamic equilibrium parameters reveals that a relatively small increase in pressure can affect both, the equilibrium parameters and the reaction rates. As a result, the specific required energy for the reaction ($$\Delta \mathrm{H}/\mathrm{SEI}$$ Δ H / SEI ) shows an optimum, but only 8% of the electrical input energy is spent for CO2 dissociation at these optimum conditions.
