N2 - A nanosecond repetitively pulsed discharge in a quartz capillary filled with flowing synthetic air was investigated as a benchmark to address the mechanism of fast gas heating for conditions of up to complete dissociation of O2 and heating of a few thousand K occurring during the near afterglow phase. Electric current, electric field, gas temperature, energy deposition, and O atom concentrations were measured with respect to time. A 2-dimensional model was used to simulate discharge initiation and early breakdown, while a detailed 0D kinetic model was used to address the afterglow phase and fast gas heating. The high oxygen dissociation degree enables investigation of the key role played by O atoms in the fast gas heating chemistry.
