We report the observation and analysis of ion cyclotron emission (ICE) in the Wendelstein 7-X (W7-X) stellarator during discharges without a significant fast-ion population. In these experiments, ICE is observed using the strap of the ICRF antenna, while remaining undetectable on the B-dot probes during ECRH-only phases. At low electron densities, …

The thermal performance of a carbon fibre composite-copper monoblock, a sub-component of a fusionreactor divertor, was investigated by finite element analysis. High-accuracy simulations were createdusing an emerging technique, image-based finite element modelling, which converts X-ray tomogra-phy data into micro-structurally faithful models, captur…

The chosen materials for plasma facing components for the deuterium/tritium phase of ITER are beryllium and tungsten. These materials have already been widely investigated in various devices like ion beam or electron beam tests. However, the operation of this material combination in a large tokamak including plasma wall interaction, material degrad…
