The provision of a particle and power exhaust solution which is compatible with first-wall
components and edge-plasma conditions is a key area of present-day fusion research and …

We studied the influence of thin, electro-chemically grown tungsten (W) surface oxide films
on hydrogen isotope release from W. As deuterium (D) reservoir underneath the oxide, we …

We performed a direct comparison of deuterium retention and release from tungsten in
presence or in absence of oxygen impurities. A single crystal of W (110) was used to …

Abstract FESTIM (Finite Element Simulation of Tritium In Materials), is a versatile open-
source finite element code developed in Python for simulating hydrogen transport in …

Bulk tungsten samples were irradiated sequentially with 20 MeV tungsten ions and exposed
to deuterium plasma. The experiments were performed in order to simulate the displacement …

The interaction of hydrogen (H) with dislocations in tungsten (W) must be understood in
order to model the mechanical response of future plasma-facing materials for fusion …

Herein we investigate absorption and desorption of hydrogen in the sub-surface of tungsten
via density functional theory. Both the near-surface diffusion and recombination of a bulk …

In order to simulate hydrogen charging and discharging cycles of mechanically loaded
structures, an analytical solution for the differential equation of trapping kinetics is proposed …

The impact of helium (He) plasma exposure with He fluxes relevant for ITER and WEST on
the near-surface microstructure of polycrystalline tungsten (W) is investigated by coupling …

The molecular dynamics simulations of trapping of hydrogen atoms in tungsten are
presented. The simulations reveal formation of platelet-like structures of self-trapped …
