Abstract :
Although it is generally recognized that the current IC technology is applicable to next step devices, the capability of current IC antennas to efficiently couple power to next step plasma is sometimes questioned. The ITER design effort has identified requirements for an acceptable performance. ITER-like IC antennas, fulfilling or possibly exceeding ITER requirements and designed for long pulse operation (1000 s) are currently being developed at Cadarache. In the paper, their essential features are described. Applications to existing and next step devices am discussed.
