Abstract

A nanosecond repetitively pulsed discharge initiated in a quartz capillary tube filled with a flowing N₂:O₂ mixture, is used as a platform to investigate the depopulation mechanisms of the N₂(C³Π_u, v = 0) state of molecular nitrogen, at conditions of high specific energy deposition. The effect of a variable energy deposition is investigated by varying the tube diameter, and the total transmitted current. Upon increase of the specific deposited energy, it is found that, in pure nitrogen, an additional collisional depopulation mechanism appears, and dominates radiative decay and quenching by ground state N₂ molecules, when the specific deposited energy is large enough. The possible nature of this process is discussed.
