Vortex formation and transport in 2D magnetized nonneutral bounded plasmas

Summary form only given, as follows. The nonlinear behaviors of the magnetized nonneutral plasmas in two-dimensional cylindrical and Cartesian geometries are studied with particle-in-cell codes. In the (r,/spl theta/) cylindrical geometry, the self-induced radial electric field E/sub r/ due to charge nonneutrality causes E/spl times/B velocity shear, which induces some instabilities to form various vortex patterns and changes the transport behaviors. The effects of control parameters such as the applied magnetic field B, the electron-ion charge nonneutrality, and a external drive voltage on the vortex formation and the radial particle fluxes are investigated. In the (x,y) rectangular geometry, the dust oscillation due to induced space-charge field and the large inertia of dust is shown under slowly turning magnetic field even in the charge neutral plasma. The charge to mass ratio of the dust and the differences of charge densities among electrons, ions, and dusts play important roles of the oscillation. The flux changes and the pattern formation of dusts for various control parameter are examined.
