Resistive drift modes in general geometry
A global approach for calculating resistive drift modes is developed, which does not use a ballooning formalism but solves the three-dimensional eigenvalue problem directly. The drift-wave model is based on linearized two-fluid equations with cold ions and electrostatic perturbations. For an axisymmetric model equilibrium results from the global approach are compared to those following from a ballooning approximation. For consistent equilibria the global approach is used to investigate the structure of resistive drift modes in tokamak configurations with positive/negative shear as well as in straight and toroidal l=2 - stellarator configurations.
