CHARACTERIZATION OF PLASMA GENERATION IN BUBBLES WITH A PLASMA GUN
Résumé
Plasma interactions with liquids has drawn much attention over the past few years considering the interest of water decontamination or treatment of pharmaceutical products. In this context, we studied the potential of low temperature plasmas created inside bubbles using a Plasma Gun (PG) from which the capillary exit is immersed into liquids. Plasma generation inside rare gas bubbles, as well as bubble growth and shape modifications were evidenced through timeresolved ICCD imaging. In this work, we performed experiments in distilled and tap water. For the same used gas, results clearly show that the plasma propagation inside the bubbles and the bubbles behaviour are strongly dependent of the liquid conductivity. These observations, not only, show the importance of the characteristics
of the liquid on the production of the reactive species, but also the importance of the evolution of these characteristics during the treatment time.
