In high recycling and detached plasma regimes the recycling region largely defines the properties of the whole scrape-off layer plasma by setting up the density and temperature profiles. As detachment approaches, the plasma temperature in the vicinit

The 2D simulations of edge plasma transport show that unlike some earlier publications, the impurity radiation loss per se does not cause the bifurcation-like transition to detached divertor regime. However, for the case where anomalous plasma transp

The ITER divertor, in its full-power operation phase, will need to withstand steady-state heat fluxes of up to 10 MW•m−2. In addition, “slow” plasma transients such as re-attachment events must be considered, during which the surface heat flu

Molecule-Activated Recombination (MAR) effect is re-considered in view of divertor plasma conditions. A strong isotopic effect is demonstrated. In deuterium plasmas, the reaction chain through D2+ formation, usually considered dominant and included i

Future tokamak reactors of conventional design will require high levels of exhaust power dissipation (more than 90% of the input power) if power densities at the divertor targets are to remain compatible with active cooling. Impurity seeded H-mode di

Divertor plasma detachment is analyzed from the viewpoint of energy and particle balance in the edge plasma. It is shown that volumetric recombination and impurity radiation losses are responsible for the transition to the detached plasma regime, whe

Deposition and fuel retention profiles in low power hydrogen L-mode plasmas and neon (Ne) seeded ITER DT burning plasmas have been investigated. Two different Ne seeded plasma backgrounds with varying sub-divertor neutral pressures but the same Ne im

The dissipative divertor for the power and particle exhaust in a tokamak relies heavily on strong impurity radiation inside the divertor volume. In the present paper, the influence of the cross-field transport inside the divertor volume on the radiat
