Method of Control o Multiple Contraction in the volume of Weakly Ionized Plasma by Standing Acoustic Wave Excitation.

This invention is a process that uses a standing acoustic wave in the volume of weakly ionized plasma to control the initiation of contraction (transition to arc) in certain designated places – the antimodes of the standing wave.
