| Outline of Final Research Achievements |
Power and particle handling by plasma-facing components (PFCs) such as divertor will be one of the most critical issues, affecting the successful operation of a fusion power reactor. Heat fluxes onto the divertor predicted by the most recent scaling law will be far more than those that can be handled by the current design based on a tungsten target brazed on a copper alloy heat sink. As a possible solution, the use of liquid metals has been proposed over the past decade or so, and most recently liquid convection has been found effective not only heat removal but particle removal. In the present work, electromagnetic forced convection is proposed and its proof-of-principle experiments have been conducted successfully.
