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 …

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 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 …

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 …

Microelectromechanical systems (MEMS)-based sample carriers became a breakthrough for
in situ inspection techniques, especially in transmission electron microscopy where the …

Helium (He) plasma irradiation to tungsten (W) leads to morphology changes in nanometer
scale by the formation and growth of He bubbles. Initially pinholes and protrusions are …

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 …

The interaction of H or He atoms with a core of edge and screw dislocations (SDs), with
Burgers vector a 0/2$\left\langle {\rm 1}\,{\rm 1}\,{\rm 1}\right\rangle $, is studied by means of …

Low-energy helium (He) plasma irradiations were conducted on ruthenium (Ru) and
rhenium (Re), which have hexagonal close packed (HCP) crystal structures. Growth of linear …

The concentration of helium in tungsten fuzz-like nanostructures has been measured by
means of thermal desorption spectroscopy. Fuzz was formed on the W surface under …
