Abstract

The experimental observation of a tripolar vortex, three aligned vortices with alternate sign of polarity of rotation, in a plasma was discussed. It was found that the net momentum transfer during the charge-exchange interaction produced an effective force acting on ions. The analysis suggested that the effective force dominates the ambipolar-electric field and drives the anti-E×B vortical motion of ions.
