The compact DBD reactor implements the Venturi-DBD concept where both electrodes are covered by glass dielectrics each with a thickness of \u2206 = 1 mm, which are separated by the gap width d = 3 mm. The electrodes are made of copper and have rectangular shape with a length of 6.6 cm and width of 1.1 cm and are 2 mm thick. Plasma source is operated sinusoidally at a frequency of 24 kHz with applied voltages from 1.8 to 3.4 kV and pressures between 100 and 650 mbar.

\nThe size of thesmallest element in the plasma domain is 0.15 um. The size of the time step is adaptively determined keeping the relative error of the solver below the tolerance of 0.0001.
Electrical measurements:
\nBandwidth of voltage proble: 75 MHz; bandwidth of current probe: 120 MHz
Fluid-Poisson model:
\nA time-dependent, spatially one-dimensional fluid model was applied for the theoretical description and analysis of the investigated DBD. The fluid model includes balance equations for the particle number densities of electrons and several neutral and charged heavy particles, as well as for the electron energy density, coupled with Poisson's equation. Flux boundary conditions taking into account partial reflection of particles were employed for electrons and heavy particles. In addition, the emission of secondary electrons caused by positive ions impinging onto the surface was considered for the electron. Also, the accumulation of surface charges on the dielectrics was taken into account. The model equations were solved fully coupled by means of the finite element method using the software COMSOL Multiphysics.
Electrical measurements:
\nThe electrode voltage was monitored by means of the high-voltage probe P6015A, Tektronix Inc., USA. The current probe TCP0030, Tektronix Inc., USA was used to measure the electrical current. Both the voltage and the current probe were connected to an 1 GHz digital oscilloscope with four channels (DPO4104, Tektronix Inc., USA).
The measured voltage signals at the powered electrode was used as input for the modelling studies.
