Abstract
The analysis of the results of experimental investigations of equilibrium, interaction and dynamics of vortex structures in pure electron and gas-discharge electron nonneutral plasmas during the time much more than the electron-neutral collision time has been carried out. The problem of long confinement of the column of pure electron plasma in Penning-Malmberg trap is considered. The mechanism of self-sustaining long-lived stable vortex structure in gas-discharge nonneutral electron plasma is proposed. The collapse of electron sheath in gas-discharge plasma of Penning cell is described. The analysis of the interaction between the stable vortex structure and the symmetric electron sheath, as well as of the action of vortex structures on the transport of electrons along and across the magnetic field is made.
