ICRF heating is a favorable high-density plasma heating method, since the ICRF wave can propagate in high-density plasma. ICRF heating in a helical reactor was calculated by using an antenna code and a ray tracing code assuming high-density plasma without resonance layers of α-particles in the plasma core. Enough loading resistance and a low electric field inside the ICRF antenna was obtained. Strong heating of plasma is expected in high-density plasma by heating electron and tritium, especially with the configuration of the second harmonic resonance layer of tritium on the magnetic axis shifted onto the saddle point.
