The feasibility of the slow-wave structure as an ICRF launcher is studied. The well-defined travelling-wave spectrum of this structure makes it a plausible candidate for current-drive experiments. Using a model which is realistic in ICRF experiments, the impedance function, the propagation constant, and the damping length along the structure are calculated as a function of plasma/antenna separation. We find that with reasonably accurate control of plasma position and sufficient spacing between the plasma and antennas, which can be expected from reactors, the use of the slow-wave structure for ICRF launching is feasible.
