Observation of accelerated beam ion population during edge localized modes in the ASDEX Upgrade tokamak
(IOP Publishing, 2019)
The interaction between fast-ions and edge localized modes (ELMs) is investigated by means of fast-ion loss detector measurements. Fast-ion losses are increased during ELMs exhibiting a 3D filamentary-like behaviour. An ...

Ion heat transport dynamics during edge localized mode cycles at ASDEX Upgrade
(IOP Publishing, 2018)
The edge ion heat transport is analyzed in ASDEX Upgrade (AUG) by combining a comprehensive set of pedestal measurements with both interpretive and predictive modelling. The experimentally determined ion heat diffusivities, ...

Velocity space resolved absolute measurement of fast ion losses induced by a tearing mode in the ASDEX Upgrade tokamak
(IOP Publishing, 2018)
Absolute flux of fast ion losses induced by tearing modes have been measured by means of fast ion loss detectors (FILD) for the first time in RF heated plasmas in the ASDEX Upgrade tokamak. Up to 30 MW m−2 of fast ion ...

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. ...
