Abstract

The design of fast-wave current drive (FWCD) antennas combines the usual antenna considerations (e.g. the plasma-antenna interface, disruptions, high currents and voltages, and thermal loads) with new requirements for spectral shaping and phase control. The internal configuration of the antenna array has a profound effect on the spectrum and the ability to control phasing. The authors elaborate on these considerations, using a proof-of-principle (POP) experiment designed for the DIII-D tokamak. The extension of FWCD for machines such as the International Thermonuclear Experimental Reactor (ITER) will require combining ideas implemented in the POP experiment with reactor-relevant antenna concepts such as the folded waveguide
