HCI Issues in Tokamak Fusion Plasmas
نویسنده
چکیده
Thermonuclear fusion powers our universe and is a most promising option for electricity and hydrogen fuel generation within a future sustainable and environmentally benign energy scenario. We shortly describe the current status of magnetic fusion research on its way to the international tokamak experiment ITER, for which construction at the European site Cadarache (France) starts in the near future and first plasma operation is expected in about ten years from now. In the adopted EU strategy for international fusion R&D, ITER is the first part of a ‘broader approach to fusion’ toward a fusion demonstration reactor (‘DEMO’) which can supply electricity into a power grid before the mid of this century. We then discuss the role of highly charged ions (HCI) for magnetic fusion (plasma transport, heating, edge and divertor plasmas, and diagnostics). Finally, we present two illustrative examples from our own work on HCI atomic and surface collisions with relevance for magnetic fusion plasmas.

Review of D - T Experiments Relevant to Burning Plasma
Progress in the performance of tokamak devices has enabled not only the production of significant bursts of fusion energy from deuterium-tritium (D-T) plasmas in the Tokamak Fusion Test Reactor (TFTR) and the Joint European Torus (JET) but, more importantly, the initial study of the physics of burning magnetically confined plasmas. TFTR and JET, in conjunction with the worldwide fusion effort, ...
