Properties of microturbulence in toroidal plasmas with reversed magnetic shear
Electrostatic drift wave turbulence in tokamak plasmas with reversed magnetic shear is studied using global gyrokinetic particle simulations. The linear eigenmode of the ion temperature gradient (ITG)...

Unified theory of resistive and inertial ballooning modes in three-dimensional configurations
Analytic results for the stability of resistive ballooning modes (RBMs) and electron inertial ballooning modes are obtained using a two-scale analysis. This work generalizes previous calculations used...

A procedure is described for evaluating particle pinches to be used in interpreting particle diffusion coefficients from measured density and temperature profiles in the edge pedestal of tokamak plasmas. Application to the interpretation of two DIII-D [J. Luxon, Nucl. Fusion 42, 614 (2002)]. discharges yields new information about particle pinches and particle diffusion coefficient profiles in the edge pedestal. ©2009 American Institute of Physics
