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 beryllium erosion by helium plasma irradiation is studied at the PISCES-B linear plasma device and interpreted using the accompanying simulations by the ERO code. The influence of plasma conditions and varying negative biasing of the Be plasma ta

On hydrogen transport in the first wall material of fusion devices in the presence of a broadband distribution of traps over the trapping energy

Autor: Sergei Krasheninnikov, E.D. Marenkov

Publikováno v: Physics Letters A. 378:1526-1530

The dynamics of hydrogen dissolved in a sample with continuous distribution of traps over trapping energy φ ( e ) ∝ exp ( − α e ) ( e = E / T is the ratio of trapping energy E to the sample's temperature T) is considered. Assuming that the hydr

On gas desorption from the tokamak first wall during edge localized modes

Autor: E.D. Marenkov, Roman Smirnov, Sergei Krasheninnikov

Publikováno v: Plasma Physics Reports. 39:867-872

The effect of gas desorption from the tokamak first wall on the pedestal recovery in the H-mode after an edge-localized-mode burst is considered. Results of FACE code simulations of hydrogen desorption from a beryllium wall are presented. It is found
