Plasma parameters of microarcs towards minuscule discharge gap - DatasetThis dataset contains plasma parameters of microarcs generated between a cooled copper anode and a ceriated tungsten cathode by means of a one-dimensional unified non-equilibrium model for gap lengths between 15 and 200 µm and current densities from 2x10^5 up to 10^6 A/m^2. The data show that the decrease of the gap length down to a few tens of micrometers for a given current density results in a progressive shrinking of the quasineutral bulk in the microplasma and its complete disappearance. The decrease of the gap length further leads to an increase of the discharge voltage and the electron temperature, and to slightly less heating of the gas.
