The installation of new 140 GHz systems for electron cyclotron heating on the tokamak ASDEX-Upgrade and the stellarator W7-AS with a power of 2 MW each and 3 s pulse length is underway. These systems use gyrotrons, developed by the Institute of Applied Physics, Nizhny Novgorod, and built by Toriy in Russia, as high power mm-wave sources. The gyrotrons can be operated for 3 s with 0.5 MW and for 1 s with 0.7 MW EHF output. The transmission of the millimetre wave power is realized by a combination of beam waveguides and corrugated HE{sub 11} waveguides. Components for transmission and high power diagnostics as well as first results are described together with the system.
