The global wave code LION was designed to study ICRF and Alfvèn wave heating in toroidal geometry, solving a second order system of differential equations, with the simplification E(parallel) = 0, and using the dielectric tensor of a homogeneous plasma. The paper discusses the assumptions and limitations of the method used, and presents the latest improvements. These include absorption by ions at harmonics of the cyclotron frequency and some aspects of the electron dynamics: Landau damping and transit-time magnetic pumping.
