To combine powers from a set of gyrotrons and to switch the combined wave beam between a number of output channels, various kinds of multiplexers can be used. Especially, narrow-band frequency diplexers in connection with small frequency-shift keying

For the upper launchers of the 170 GHz electron cyclotron resonance heating (ECRH) and current drive system of ITER, "remote steering" based on the imaging properties of corrugated square waveguides is the reference option. In the last years, a varie
