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

The tungsten (W) material in the high heat flux regions of the ITER divertor will be exposed
to high fluxes of low-energy particles (eg H, D, T, He, Ne and/or N). Combined with long …

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 …

Helium plasma irradiation to various metals leads to peculiar morphology changes as
forming fiberform nanostructures called fuzz when a certain set of conditions is satisfied. In …

Helium plasma irradiation on metal surfaces leads to the formation of metallic fuzzy
nanostructures accompanied by the growth of helium bubbles in metals. The mechanism 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 …

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

Isolated regions of nano-tendril bundles (NTBs) have been grown on tungsten surfaces
exposed to low-pressure direct-current helium plasma discharges operating with the …

It is now well-known that under exposure to a helium (He) plasma at elevated temperatures,
a tungsten (W) surface is modified by the growth of a fibreform nano-structure referred to as …

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 …
