Abstract:

The design of the quasi optical (q. o.) RF output system for the first industrial prototype of the European 170 GHz, 2 MW, CW coaxial cavity gyrotron for electron cyclotron heating and current drive in ITER has been verified at a low power level. Results of measurements with a high quality TE_34,19-mode generator are in good agreement with the design calculations. This strengthens the confidence both to the employed design codes and to the manufacturing quality of the launcher and mirrors.
