Isotope dependence of energy, momentum and particle confinement in tokamaks
(Cambridge University Press, 2020)
The isotope dependence of plasma transport will have a significant impact on the performance of future D-T experiments in JET and ITER and eventually on the fusion gain and economics of future reactors. In preparation for ...

I-mode pedestal relaxation events in the Alcator C-Mod and ASDEX Upgrade tokamaks
(IOP Publishing, 2022)
In some conditions, I-mode plasmas can feature pedestal relaxation events (PREs) that transiently enhance the energy reaching the divertor target plates. To shed light on their appearance, characteristics and energy reaching ...

Stationarity of I-mode operation and I-mode divertor heat fluxes on the ASDEX Upgrade tokamak
(Elsevier, 2019)
Recent I-mode investigations from the ASDEX Upgrade tokamak are reported. It is shown that neutral-beam-injection heated I-modes can be stationary, which is important in terms of extrapolability towards future fusion ...

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, ...

Effects of density gradients and fluctuations at the plasma edge on ECEI measurements at ASDEX Upgrade
(IOP Publishing, 2018)
Electron cyclotron emission imaging (ECEI) provides measurements of electron temperature (Te) and its fluctuations (δTe). However, when measuring at the plasma edge, in the steep gradient region, radiation transport effects ...
