Development of hybrid frequency couplers for non-inductive current generation in a tokamak
Used initially as a heating method in order to reach the temperature required for the fusion of a thermonuclear plasma, hybrid waves have been shown to be a more efficient method for non-inductive current drive in a tokamak. The size and objectives of a machine such as ITER led to the design of new antennae made of oversized waveguides. This new concept of antenna will be more simple, more robust and will be able to transmit the same if not more power than the present antennae. This concept contributed to the development of a new code called ALOHA (for Advanced LOwer Hybrid Antenna) which, in the end, will be able to give the characteristics and the behaviours of this new oversized antennae in front of a tokamak plasma.
