Abstract

This report shows the progress achieved in simulations of thermal and non-thermal effects which may appear for high power ECRH in the W7-X stellarator (under construction in Greifswald, Germany). Simulations are carried out with the new ray tracing code TRAVIS which was developed for electron cyclotron studies in arbitrary 3D magnetic configurations, with emphasis on heating, current drive and ECE diagnostic.
