Abstract :
The virtual German-Italian-Russian Helmholtz- Institute "Advanced ECRH for ITER" runs a program FADIS aimed to develop a system for combining outputs from a set of gyrotrons and toggling the combined beam with kHz-frequency between two launcher for dedicated electron cyclotron heating and current drive in fusion experiments. A diplexer prototype fed by a 140 GHz gyrotron with ~0.5- MW, ~ 1-s pulses operated in good agreement with theory.
