Abstract :
The main heating method for the stellarator W7-X which is currently under construction is Electron Cyclotron Resonance Heating (ECRH) at 140 GHz. To meet the physical and technical demands of the W7-X machine a 10 MW ECRH system with CW capabilities has been constructed. To test the performance of the system and to measure the beam propagation characteristics, a prototype system is currently under construction. In this paper we describe this system and present first RF measurements on beam propagation.
