A fast edge charge exchange recombination spectroscopy system at the ASDEX Upgrade tokamak
(AIP Publishing, 2017)
In this work, a new type of high through-put Czerny-Turner spectrometer has been developed which allows us to acquire multiple channels simultaneously with a repetition time on the order of 10 μ s at different wavelengths. ...

Investigation of inter-ELM ion heat transport in the H-mode pedestal of ASDEX Upgrade plasmas
(IOP Publishing, 2017)
The ion heat transport in the pedestal of H-mode plasmas is investigated in various H-mode discharges with different pedestal ion collisionalities. Interpretive modelling suggests that in all analyzed discharges the ...

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 ...

The radial localization of the transition from low to high confinement mode in the ASDEX Upgrade tokamak
(Institute of Physics Publishing, 2024)
A novel experimental method is applied to localize the initial suppression of turbulence, in the form of density fluctuations, at the transition from the low (L-) to the high (H-) confinement mode in toroidal magnetic ...
