Summary
The usually applied scheme of electron heating in fusion plasmas by millimeter waves is limited regarding the plasma density. At the ASDEX Upgrade tokamak, which is operated by Max-Planck-Institut für Plasmaphysik in Garching, new schemes have been developed that allow efficient electron heating at higher density. These schemes are not only important to extend the operational space of ASDEX Upgrade but could also be used in the Wendelstein 7-X stellarator that is currently being built by the Greifswald branch of Max-Planck-Institut für Plasmaphysik.
