A ceramics-free waveguide for ITER ion cyclotron wave system

A ceramics-free waveguide for the high-power International Thermonuclear Experimental Reactor ion cyclotron (ITER IC) system (15-80 MHz), which is a TEM waveguide supported mechanically by T-shaped ridged waveguides, is proposed. The transmission-line theory shows that this waveguide has power handling capability of more than 3 MW, where an optimized antenna impedance is used for the ITER plasma parameters. The transmission line model used for the analysis is verified by the experiments on a one-tenth scale model.<
