Abstract

This paper proposes a Traveling Wave Antenna for ICRH heating of T-15MD located below the equatorial plane of the tokamak for operation at 60MHz. Resonant ring feeding allows the recirculation of the RF power that is not radiated to the plasma and the termination of the TWA section in its iterative impedance. The paper describes the antenna design, the feeding ring tuning algorithm and expected performances of this antenna concept. The chosen geometry of the TWA sections is compatible with that of a future reactor and therefore this ICRH antenna system for T-15MD also represents a test bed for DEMO.
