Fig. 1 Schematic of LHD plasma

Caption

Left: Plasma has a twisted doughnut shape. Top right: Cross section of LHD plasma. Heat from the plasma gradually escapes to the outside. The divertor plate (heat-receiving plate), which receives this heat directly, is subjected to a particularly large heat load. Lower right: Spatial distribution of plasma temperature and density. Turbulence tends to occur with the largest gradient. The propagation process of turbulence is an unresolved issue.
