The formation of nanostructure on tungsten (W) surface due to Helium (He) plasma irradiation can be harmful for fusion reactors. Up to now, W nanostructure growth was investigated mainly without sputtering. Under sputtering regime, nanostructure grow

The generation of tungsten fuzzy nanostructure by exposure to helium plasma is one of the important problems for the use of tungsten material as divertor plates in nuclear fusion reactors. In the present paper, the formation mechanisms of the helium

Arcing was initiated in steady state helium plasmas by negatively biasing a tungsten electrode to around −500 V. On the tungsten electrode, nanostructures were grown by the plasma irradiation. In this study, we characterized the property of the ini

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 present paper, the fuzzy nanostructure's formation has been successfu

Arcing is a long-standing plasma?surface interaction issue, and the issue is currently being revived. This paper assesses the impact of arcing in fusion devices based on the observations in JT-60U, the Large Helical Device (LHD) and the linear divert
