Erosion of nanostructured tungsten by laser ablation, sputtering and arcing
Mass loss of nanostructured tungsten, which was formed by helium plasma irradiation, due to laser ablation, sputtering, and arcing was investigated. Below the helium sputtering energy threshold (<117eV), sputtering by impurity gases such as nitrogen and oxygen was dominant. Sputtering yield becam...
