A new divertor configuration is suggested as a possible solution to the problems of high heat flux and erosion at the divertors in large high-power tokamaks. The proposed configuration is a toroidally symmetrical slot in the divertor that allows part of the edge plasma and most of its power to enter a cavity in a thin annular sheet. The large surface area of the sheet is exposed to interaction with gas in the cavity. This results in radiation and a reflux of fast neutral atoms, both of which transport power to the cavity walls. The heat flux is reduced because the power is spread over a much larger area. Erosion due to sputtering is also reduced because the decreased power flux reduces the sheath potential and, therefore, the average ion impact energy. Sputtering by fast neutrals should not be a serious problem because neutrals are not accelerated by a sheath as are ions. Helium ash and impurity atoms that are ionized within the cavity tend to be trapped there by the electric field that must exist throughout the source region in order to make the removal rates for electrons and ions both equal to the production rate.
