Intense plasma emission induced by jet-to-jet coupling in atmospheric pressure plasma arrays

Intense plasma emissions were achieved via jet-to-jet coupling in a multi-tube array-based plasma device in ambient air. The plasma array device consisted of a central glass tube encircled by an array of hollow glass tubes. A single plasma jet was induced via jet-to-jet coupling and enabled significantly increased plasma emission despite a negligible change in power consumption. An increase in the number of outer tubes yielded a greater number of charged particles involved in the plasma process and resulting in the achievement of higher plasma emission in the coupled system.
