Modeling of COMPASS tokamak divertor liquid metal experiments

Nuclear Materials and Energy, 2020
Two small liquid metal targets based on the capillary porous structure were exposed to the divertor plasma of the tokamak COMPASS. The first target was wetted by pure lithium and the second one by a lithium-tin alloy, both releasing mainly lithium atoms (

Innovative Tungsten Coatings for an Application in Modern and Future Fusion Devices

Metals, 2023
Tungsten is foreseen presently as the plasma-facing material for divertors in fusion power plants. In order to achieve durable operation of divertors of current fusion reactors, an efficient way of maintaining the divertor functionality is needed.

Titanium and Tantalum Used as Functional Gradient Interlayer to Join Tungsten and Eurofer97

Journal of Nuclear Engineering, 2022
For the DEMO reactor, tungsten is considered as an armor material. Eurofer97 is planned to be used as a structural material for the first wall and in the divertor region, especially for the shielding liner component.

Engineering of a FGM Interlayer to Reduce the Thermal Stresses Inside the PFCs

Applied Sciences, 2022
A substantial contribution of the stresses that arise inside the Plasma-Facing Components (PFCs) when a heat load is applied is caused by the mismatch of the Coefficient of Thermal Expansion (CTE) between the armor, usually made of tungsten (W), and the ...

Tungsten fibre-reinforced composites for advanced plasma facing components

Nuclear Materials and Energy, 2017
The European Fusion Roadmap foresees water cooled plasma facing components in a first DEMO design in order to provide enough margin for the cooling capacity and to only moderately extrapolate the technology which was developed and tested for ITER.
