Machine-learned interatomic potential for sputtering of tungsten-boron surfaces
Alexandre Bergero, Jesper Byggmästar, Fredric Granberg
Boronization, where boron is deposited onto tungsten surfaces, is a key technique to reduce plasma contamination, such as oxygen in Tokamak fusion reactors. The exact interaction b…

Four regimes of primary radiation damage in tungsten
Jesper Byggmästar, Ville-Markus Yli-Suutala, Aslak Fellman +3
We observe for the first time in silico the transition to a linear regime in the primary damage production in tungsten. As the critical plasma-facing material in fusion reactors, r…

New insight into quantifying vacancy distribution in self-ion irradiated tungsten: a combined experimental and computational study
Zhiwei Hu, Jintong Wu, François Jomard +2
In this work, we propose a new approach based on positron annihilation spectroscopy to estimate the concentration of vacancy-type defects induced by self-ion irradiation in tungste…
