DIVERTOR PLASMA STUDIES ON DIII–D: EXPERIMENT AND MODELING

W.P. West, et al. DIVERTOR PLASMA STUDIES ON DIII–D: EXPERIMENT AND MODELING GENERAL ATOMICS REPORT GA–A22461 iii In a magnetically diverted tokamak, the scrape-off layer (SOL) and divertor plasma provides separation between the first wall and the core plasma, intercepting impurities generated at the wall before they reach the core plasma. The divertor plasma can also serve to spread the heat and particle flux over a large area of divertor structure wall using impurity radiation and neutral charge exchange, thus reducing peak heat an
