This research investigates the interaction between high-speed tungsten (W) dust and
plasma-facing components (PFCs) in fusion reactors, particularly focusing on W walls …

The integrity of plasma-facing components (PFCs) in fusion reactors is severely tested by
high-velocity dust collisions, which occur during explosive events such as runaway electron …

Dust-surface collisions impose size selectivity on the ability of dust grains to migrate in
scrape-off layer and divertor plasmas and to adhere to plasma-facing components. Here, we …

Dust velocity in fusion devices covers a wide range (several hundreds of m/s to over 10
km/s), which can cause various interactions between energetic dust grains and wall …

Empirical studies of dust–surface collisions for metal and carbon projectiles impacting on
metal targets in the velocity range from a few m/s to those in excess of 1km/s have been …

We report results of systematic molecular-dynamics computations of the elastic properties of
single-crystalline tungsten containing structural defects, voids and overpressurized He …

Classical molecular dynamics has been used to study the interactions between tungsten (W)
plasma-facing materials (PFMs) and dust grains. The impact velocity of dust grains is in the …

Mechanical dust-wall collisions are unavoidable in fusion devices and their accurate
modeling is essential for the understanding of dust transport. The MIGRAINe dust dynamics …

Dust plasma readily forms during hypervelocity impact, which serves as a source of plasma
macroscopic charge separation and strong electromagnetic fields. In this study, we examine …

We report a systematic computational analysis of the mechanical behavior of plasma-facing
component (PFC) tungsten focusing on the impact of void and helium (He) bubble defects …
