Power exhaust is a crucial issue for future fusion reactors. Divertor detachment and the required power dissipation fractions of about 95% are foreseen to be achieved by impurity seeding. In a tokamak. at high seeding levels the radiation often concentrates in a small region inside the confined plasma near the X-point. https://www.bekindtopets.com/hot-super-Chervo-Marco-Jacke-Herren-limited-grab/
