Abstract
We present a model of an ECWR discharge, where electrons are heated by resonant absorption of electron cyclotron waves induced by an induction coil and propagating along a stationary magnetic field. We concentrate on a cylindrical discharge geometry; the external magnetic field is perpendicular to the cylinder axis. Using a finite element scheme, the time and space dependence of the induced electromagnetic fields are calculated under the assumption of a homogeneous plasma density. From these, the power deposition in the discharge, and the resonance condition for the external magnetic field can be determined.
