The Future of Tore Supra

A vision for a long-term scientific and technological development for Tore Supra is highlighted in this paper. The proposed Tore Supra developments aim at consolidating the physics and technology of continuous tokamak operation on the route toward the development of a fusion reactor. This ambitious programmatic vision requires a significant power upgrade of the rf heating and current drive systems to operate Tore Supra up to the 20-MW power level in the long-pulse regime, i.e., at a convected heat flux up to 10 MW/m² on the actively cooled plasma-facing components. This would allow an ambitious exploration of physics and technology issues of continuous tokamak operation in synergy with the stellarator program.
