In this paper, we report a molecular beam mass spectrometer study of a time‐modulated radiofrequency (RF)‐driven atmospheric pressure plasma jet in Ar + 1% O₂. Time‐resolved measurements of the absolute density of O₃ during the RF modulation period revealed a temporal increase of O₃ densities at the start and end of the power modulation. This increase correlates with the increase in O₂ due to plasma‐induced transient vortices in the gas jet. Pseudo‐one‐dimensional plug flow modeling of the axial species densities as a function of distance match well with the experimentally recorded trends. The obtained results were used to assess the importance of the O flux in previously reported ClO⁻ production in saline by the same plasma jet.

通过分子束质谱法获得的调制RF驱动的大气压等离子体射流的流出物中的空间和时间分辨的O，O3和空气密度的绝对值

在本文中，我们报告了在Ar + 1％O ₂中由时间调制的射频（RF）驱动的大气压等离子体射流的分子束质谱仪研究。在RF调制期间对O ₃的绝对密度进行时间分辨测量后发现，功率调制开始和结束时O ₃密度随时间增加。这种增加与气体射流中等离子体引起的瞬时涡流引起的O ₂的增加有关。轴向物种密度随距离变化的伪一维塞流模型与实验记录的趋势非常吻合。将得到的结果被用来评估在先前报道的CLO将O通量的重要性^- 用相同的等离子射流在盐水中进行生产。
