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 …

The Z-pinch configuration offers the promise of a compact fusion device owing to its simple
geometry, unity beta, and absence of external magnetic field coils. Increasing the axial …

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 …

Developing high performance plasma facing materials (PFMs) is one of the greatest
challenges for fusion reactors, because PFMs face unprecedented harsh environments …

We present secondary electron yield (SEY) characterization of high porosity surfaces for
multipactor-free microwave components. We first calculate the SEYs of through porosity …

Tungsten coatings with different surface morphologies and microstructures were prepared
on a reduced activation ferritic/martensitic steel CLAM by DC magnetron sputtering. The …

Complex structures on a material surface can significantly reduce the total secondary
electron emission yield from that surface. A foam or fuzz is a solid surface above which is …

Growth of helium (He) induced bubbles and fuzz in tungsten (W) and molybdenum (Mo) is
investigated using samples of W films on Mo substrates and Mo films on W substrates …

The plasma electrons bombarding a plasma-facing wall surface can induce secondary
electron emission (SEE) from the wall. A strong SEE can enhance the power losses by …

The review summarizes recent experimental results of studying heat transfer on rough
surfaces synthesized by plasma. The plasma-surface interaction leads to the stochastic …
