Tungsten will be used as the plasma-facing divertor material in the International
Thermonuclear Experimental Reactor (ITER) fusion reactor. Under high temperatures and …

Helium (He) plasma irradiation to tungsten leads to formation of He bubbles and fiberform
nanostructures called fuzz on the surface. Although the fuzz growth condition and growth …

The interaction processes between the burning plasma and the first wall in a fusion reactor
are diverse: the first wall will be exposed to extreme thermal loads of up to several tens of …

Tungsten, the material used in the plasma-facing components (PFCs) of nuclear fusion
reactors, develops a fuzz-like surface morphology under typical reactor operating conditions …

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) …

The growth of He bubbles and the resulting impact on the microstructural evolution of W are
of paramount importance to the plasma-facing materials community due to the application of …

Recently, high entropy alloy (HEA) has demonstrated superior radiation resistance to
energetic particles. In this paper, we examine the radiation response of W-based HEA …

Surface free energy has been hypothesized as the cause behind the experimental evidence
(Parish et al., 2014) of a strong correlation between crystallographic orientation and surface …

Nanostructured tungsten has been proposed as a promising option for plasma facing
materials in future fusion reactors, because compared to conventional tungsten it shows …

Based on the physical processes, such as the collisions of energetic He ions in a fuzz layer,
He+ implantations into W bulk, and surface erosion of W fuzz layer, we have modeled the …
