ABSTRACT
An improved theory for the neoclassical polarization drift of the collisionless single ion with the arbitrary time-varying radial electric field is presented. A guiding-center motion code is used to numerically study the neoclassical polarization drift of a collisionless single ion in a model tokamak geometry. The results from the improved theory are compared with the numerical results and they agree with each other very well. The improved theory can be used to study the neoclassical polarization drift due to the fast time-varying radial electric field.

    A numerical study is presented of the evolution of plasma blobs in the scrape-off layer of a tokamak, in the presence of dust. Appropriate fluid model equations for the nonlinear interchange mode in a dusty plasma are derived, accounting for the attachment of electrons and ions, as well as for...

    Neoclassical shielding is the dominant mechanism reducing the collisionless zonal flow in a tokamak. Previously, this phenomenon was analyzed in the case of an essentially homogeneous equilibrium since the wavelength of the zonal flow perturbation was assumed to be much less than the scale...

    The magnetron plasma etching of SiO2 and Si in fluorocarbon gas has been investigated. The plasma has high ionization degree, collisionless high density, and low energy ion flux (I∼1.0 mA/cm2, 30<=Ei <=250 eV at 1 W/cm2) and a controllable etch uniformity. The bulk of the plasma supports an...

    The results are discussed of a 2½ dimensional, undriven, fully open-boundary particle-in-cell simulation of symmetric, anti-parallel reconnection.
