Challenges for plasma-facing components in nuclear fusion [PDF]

open access: yesMatter and Radiation at Extremes, 2019
The interaction processes between the burning plasma and the first wall in a fusion reactor are diverse: the first wall will be exposed to extreme thermal loads of up to several tens of megawatts per square meter during ...

R&D on divertor plasma facing components at the Institute for Plasma Research [PDF]

open access: yesNukleonika, 2015
This paper is focused on various aspects of the development and testing of water cooled divertor PFCs. Divertor PFCs are mainly designed to absorb the heat and particle fluxes outflowing from the core plasma of fusion devices like ITER.

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

open access: yesApplied 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 ...
