Nanostructured fuzz growth on tungsten under low-energy and high-flux He irradiation
We report the formation of wave-like structures and nanostructured fuzzes in the polycrystalline tungsten (W) irradiated with high-flux and low-energy helium (He) ions. From conductive atomic force microscope measurements, we have simultaneously obtained the surface topography and current emission images of the irradiated W materials. Our measurements show that He-enriched and nanostructured st...
متن کاملEffect of high-flux, low-energy He+ ion irradiation on Ta as a plasma-facing material
The goal of this work is to assess Ta as a potential plasma-facing material for future fusion reactors in terms of its response to high-flux, low-energy He+ ion irradiation. Ta samples were irradiated with 100 eV He+ ions at various fluences up to 3.5 × 1025 ions m-2 while simultaneously heated at constant temperatures in the range 823-1223 K. SEM studies show that irradiated Ta surfaces underg...
متن کاملMorphologies of tungsten nanotendrils grown under helium exposure
Nanotendril "fuzz" will grow under He bombardment under tokamak-relevant conditions on tungsten plasma-facing materials in a magnetic fusion energy device. We have grown tungsten nanotendrils at low (50 eV) and high (12 keV) He bombardment energy, in the range 900-1000 °C, and characterized them using electron microscopy. Low energy tendrils are finer (~22 nm diameter) than high-energy tendrils...

SEMmicrograph of a multimodal grained tungsten material after being irradiated with 200 eV He ions at 950 C and a fluence of 1 10 m 2 showing the detachment and the nanostructuring of the small grains as well as pore formation on top of the nanostructures. The sample was etched before irradiation for better imaging of the grain boundaries. a r t i c l e i n f o
