Experimental investigations of the vortex-chain generated in the two-component plasma with the sheared flow of magnetized electrons

Abstract

We present further experimental results on the observation of electron vortices in an electrostatic plasma lens at the strong radial gradient of electron density. Anharmonic low frequency large-amplitude potential waves propagating in azimuth direction are observed. The recently observed results give additional confirmation that the observed waves are the manifestation of the vortex-chain generated at the azimuthal sheared flow of magnetized electrons compensating ion beam.
