Tungsten, the primary material under consideration as the divertor material in magnetic-
confinement nuclear fusion reactors, has been known for the last decade to form'fuzz'—a …

The performance of plasma facing components (PFCs) is critical for ITER and future
magnetic fusion reactors. The ITER divertor will be tungsten, which is the primary candidate …

Large-scale molecular dynamics simulations of post-implantation helium behavior in plasma-
facing tungsten single crystals reveal orientation-dependent depth profiles, surface evolution …

The production of energy through nuclear fusion poses serious challenges related to the
stability and performance of materials in extreme conditions. In particular, the constant …

Growth of helium (He) bubbles with different initial sizes in tungsten (W) has been
investigated by performing molecular dynamics simulations. Based on the simulation results …

For the purposes of long-term use of tungsten divertor walls, the formation process of the
fuzzy tungsten nanostructure induced by exposure to the helium plasma was studied. In the …

We present atomistic simulations that show the effect of surface orientation on helium depth
distributions and surface feature formation as a result of low-energy helium plasma …

The change in surface damage/microstructures and its effects on the hydrogen (H)
isotope/helium (He) dynamic behavior are the key factors for investigating issues of tungsten …

Tungsten is a promising plasma facing material for fusion reactors. Despite many favorable
properties, helium ions incoming from the plasma are known to dramatically affect the …

Molecular dynamics (MD) simulations are performed to derive an equation of state (EOS) for
helium (He) bubbles in tungsten (W) and to study the growth of He bubbles under a W (100) …
