“…Comparative studies of tungsten targets irradiation with high-power plasma streams generated in GOL-3 and QSPA Kh-50 facilities are being performed [10]. With applied high-energy loads > 1 MJ/m 2 , in spite of qualitative differences in types and energy distribution functions of the bombarding particles, a similar evolution in the surface morphology is observed after the exposures.…”

“…Bubbles and three different crack networks with typical cell sizes of 1000, 10 and 0.3 µm were detected after irradiation of the tungsten surface by different methods (after irradiation at the Nd:YAG laser [4], QSPA Kh-50 and GOL-3 [6], [10], PSI-2 [7], Nd:YAG laser, JUDITH-1 and GOL-3 [2], [8] [11]. The typical erosion depth is less than 20 μm [2], [10]. The thickness of the remelted layer was ~ 35 μm [2].…”

“…The newly formed crystals (cell size about 10 µm) have a typical columnar structure of molten material due to intense heat transfer to the internal layers of the tungsten sample. Crack networks with sizes of 0.3 µm are attributed to the formation of individual crystallites [10]. With loads of 4 MJ/m 2 (corresponding to unmitigated ITER type I ELMs), a frozen melt is formed on the tungsten surface instead of crack networks with cell sizes of 1000 µm (GOL-3 [2], [10]).…”

“…Big droplets, deep bubbles and waves were found on the tungsten surface. The height of the drops after repetitive loads exceeds 200 µm, which demonstrated very large erosion depth for energy density corresponding to the biggest ITER type I ELMs [2], [10].…”

In this paper, we present a brief historic overview of the research on dust in fusion devices with carbon plasma-facing components and then highlight the most recent developments in the post-carbon era of the field. In particular, we consider how the metallic dust form, mobilize, and interact with fusion plasmas and plasma facing components. Achievements in wall conditioning and associated anomalous plasma transport modification, including ELM suppression, with the powder injection technique is another focus of the paper. Capabilities of the state-of-art simulation tools to describe different aspects of dust in fusion devices are exemplified and new directions for future dust studies are brought forward.
