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 …

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

We present a theoretically-motivated model of helium bubble density as a function of volume
for high-pressure helium bubbles in plasma-facing tungsten. The model is a good match to …

We investigate helium flux effects on helium transport and surface evolution in plasma-
facing tungsten using molecular dynamics. The simulations span two orders of magnitude …

We conduct molecular dynamics simulations of helium in tungsten to study the interaction of
helium with grain boundaries. Model systems with grain boundary planes perpendicular to …

One of the most critical challenges for the successful adoption of nuclear fusion power
corresponds to plasma-facing materials. Due to its favorable properties in this context (low …

Fusion reactor environments inevitably lead to the formation of high-pressure helium
bubbles whose nucleation, growth, and diffusion strongly impact the performance of plasma …

Formation of helium bubbles impacts mechanical properties of materials used in nuclear
