We studied the influence of air on a pure AMPJs (1 slm) produced by a square-pulsed sDBD, with two discharges per applied voltage pulse. Using laser absorption spectroscopy, we measured spatiotemporal Ar(1s5) absorbance profiles, to compare its quenching in different N2-O2 shieldings in a co-flow reactor (0.1 to 3 slm and ~0 to 100% of O2). We processed this data into spatiotemporal density and effective-lifetime profiles of Ar(1s5), for both discharges.
Absence of O2 leads to the lowest peak Ar(1s5) density for both discharges and lowers the reproducibility of the first. Increasing O2 fraction increases the propagation velocity of the first discharge and decreases that of the second, with temporal profiles further altered with the radius.
Isolating the effect of O2 on AMPJs could be helpful for future applications, and the obtained data can help validate computational models.
