Abstract

Global modes of the Alfvén wave exist in tokamaks because of the equilibrium current (GAE), the toroidicity (TAE), the pressure (BAE) and the shaping of the plasma (EAE). These modes have already been studied numerically using either cylindrical kinetic or toroidal fluid plasma models; comparisons with experiments showed however important limitations and led to the recent development of the toroidal PENN code, which includes a resistive fluid and a kinetic model based on a finite Larmor radius (FLR) expansion. Using this new tool, kinetic effects are here studied for a GAE mode in a medium size tokamak.
