The EU 1 MW gyrotron for the ITER Electron Cyclotron Heating and Current Drive (EC H&CD) system has been developed in coordinated efforts from several EU institutions (EGYC) and with support of F4E. In a first experimental campaign the tube has been optimized in short pulse operation and has been conditioned for long pulse operation at the KIT teststand up to 180 s. In a second experimental campaign the tube has been transferred to SPC, EPFL, for operation in a dedicated super-conducting magnet at increased pulse length. This paper presents the main experimental results of the prototype tube achieved at KIT.
