The reduction of diffusion by plasma rotation and ion dissipative effects

The authors show that the combined effects of rotation, ion-viscosity and ion-neutral friction reduce the particle transport substantially for positive rotation and enhance the transport for negative rotation. Consequently, there exists a weak axial gradient in a cylindrical geometry with identical electrodes (at the cathode the plasma is hotter and denser than at the anode). The authors also show that because of these effects the particle confinement was appreciably better than the classical and Nernst effect
