Non-linear extended MHD simulations of type-I edge localised mode cycles in ASDEX Upgrade and their underlying triggering mechanism [PDF]
Nuclear Fusion, 2020 A triggering mechanism responsible for the explosive onset of edge localised modes (ELMs) in fusion plasmas is identified by performing, for the first time, non-linear magnetohydrodynamic simulations of repetitive type-I ELMs.A.

Nuclear Materials and Energy, 2021 Arcs, a source of dust particles and a localized erosion mechanism of the plasma-facing components, are found in all major fusion plasma devices. Measurements of arcs require diagnostics with high temporal and local resolution, which are not available at V. Rohde, M. Balden, R.

, 2021 The coating of plasma facing components (PFC) with boron significantly improves the performance of plasma operation in magnetic fusion devices. The boron layer traps residual oxygen in the vacuum vessel, thus reducing radiative losses due to collisions ...M. Dibon, V. Rohde, F. Stelzer, K. Hegele, M.

Nuclear Fusion, 2019 Abstract The ASDEX Upgrade (AUG) programme, jointly run with the EUROfusion MST1 task force, continues to significantly enhance the physics base of ITER and DEMO. Here, the full tungsten wall is a key asset for extrapolating to future devices.Meyer, H., Angioni, C., Albert, C.
