Simulation results from COMSOL and BOLSIG+ for an input voltage of 8.5 kV. (a) Electric field distribution in the entire simulation domain. (b) Electric field along the symmetry axis of the electrode system. (c) Electron energy distribution function (EEDF) determined with BOLSIG+ for air with different contents of humidity, ranging from pure water vapor to dry air, corresponding to the field in the middle of the gap. (d) Electron mobility µe and electron density ne as a function of the reduced electric field, for E/n values found in the interelectrode gap.
