Experimental conditions to suppress edge localised modes by magnetic perturbations in the ASDEX Upgrade tokamak
(IOP Publishing, 2018)
Access conditions for full suppression of edge localised modes (ELMs) by magnetic perturbations (MP) in low density high confinement mode (H-mode) plasmas are studied in the ASDEX Upgrade tokamak. The main empirical ...

Velocity-space sensitivity and tomography of scintillator-based fast-ion loss detectors
(IOP Publishing, 2018)
A simple model for the instrument function of scintillator-based fast-ion loss detectors (FILD) has been developed which accounts for the orbit trajectories in the 3D detector geometry and for the scintillator response. ...

Understanding helium transport: experimental and theoretical investigations of low-Z impurity transport at ASDEX Upgrade
(IOP Publishing, 2019)
The presence of helium is fundamentally connected to the performance of a fusion reactor, as fusion-produced helium is expected to heat the plasma bulk, while He 'ash' accumulation dilutes the fusion fuel. An understanding ...

Phase-space resolved measurement of 2nd harmonic ion cyclotron heating using FIDA tomography at the ASDEX Upgrade tokamak
(Institute of Physics Publishing, 2017)
Recent upgrades to the FIDA (fast-ion D-alpha) diagnostic at ASDEX Upgrade allow to reconstruct the fast-ion phase space at several radial positions with decent energy and pitch resolution. These new diagnostic capabilities ...
