Effect 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 × 10 25  ions m −2 while simultaneously heated...
