MAST Upgrade Divertor Facility: A Test Bed for Novel Divertor Solutions

摘要: The challenge of integrated exhaust consistent with the other requirements in DEMO and power plant class tokamaks (ITER-like alternative DEMOs, Fusion Nuclear Science Facility approaches) is well-known solution likely to be fundamental design operating scenarios chosen. Strategies have been proposed such as high main plasma radiation, but improved solutions are sought will require revised research methodologies. While no facility can address all challenges, new MAST Upgrade tokamak enables exploration a wide range divertor aspects single device their relation core (e.g., access H-mode) particular development understanding ideas. It has unique combination closed divertor, capability configurations from conventional long leg (including Super-X), fully symmetric double null (plasma structures). To extrapolate scale devices where full tests advance not feasible yet different physics mechanisms may dominate, theory-based models essential for confident performance prediction, optimization, “qualification” concept. Development validation at heart program around Upgrade. Amongst many areas explored, there strong focus on closely coupled topics detachment cross-field transport filaments), key ingredients effective reliable protection plasma-facing components scale.
