In 1959 the Journal of Nuclear Materials (JNM) was founded and is now celebrating its
Diamond Anniversary year. The present paper is part of a series in which single JNM …

In fusion reactors, surfaces of plasma facing components (PFCs) are exposed to high heat
and particle flux. Tungsten and Copper alloys are primary candidates for plasma facing …

Helium irradiation on tungsten changes the surface morphology dramatically by forming a
nanometre-sized fibreform structure which could bring about serious problems for fusion …

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 …

Molecular dynamics simulations reveal sub-surface mechanisms likely involved in the initial
formation of nanometre-sized'fuzz'in tungsten exposed to low-energy helium plasmas …

The response of a variety of W material grades to nanostructure 'fuzz'formation is explored.
W targets are exposed to He or D2–0.2 He plasmas in PISCES-B at 900–1320K to below …

The thickness x, of tungsten fuzz layers are measured for non-varying helium (He) plasma
exposure conditions spanning four orders of ion fluence $\Phi $(10 24–10 28 m− 2) and flux …

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 …

Blister formation and D retention in W have been investigated for low energy (∼ 55±15 eV),
high flux (∼ 10 22 m− 2 s− 1), high fluence (⩽ 4.5× 10 26 m− 2) ion bombardment at …

Under the anticipated operating conditions for demonstration magnetic fusion reactors
beyond ITER, structural and plasma-facing materials will be exposed to unprecedented …
