Abstract

This paper presents a numerical method to calculate full wave problems in the toroidal geometry of a tokamak using two different plasma models. The numerical method implemented in the PENN code is based on a formulation in terms of the electromagnetic potentials and a discretisation with standard bilinear or bicubic Hermite finite elements. Two models for the dielectric tensor operator yield different physical problems. The first treats the plasma as resistive fluids, the second is a kinetic model taking into account the finite size of the Larmor radii. New results are obtained for kinetic effects in toroidal geometry showing the difficulty in heating plasmas up to temperatures relevant to a tokamak reactor.
