Extensions to the charge exchange recombination spectroscopy diagnostic suite at ASDEX Upgrade
(AIP Publishing, 2017)
A new core charge exchange recombination spectroscopy diagnostic has been installed in the ASDEX Upgrade tokamak that is capable of measuring the impurity ion temperature, toroidal rotation, and density on both the low ...

Divertor, scrape-off layer and pedestal particle dynamics in the ELM cycle on ASDEX Upgrade
(IOP Publishing, 2018)
In addition to the relaxation of the pedestal, edge localised modes (ELMs) introduce changes to the divertor and scrape-off layer (SOL) conditions. Their impact on the inter-ELM pedestal recovery is investigated, with ...

Overview of progress in European medium sized tokamaks towards an integrated plasma-edge/wall solution
(IOP Publishing, 2017)
Integrating the plasma core performance with an edge and scrape-off layer (SOL) that leads to tolerable heat and particle loads on the wall is a major challenge. The new European medium size tokamak task force (EU-MST) ...

Implementation of synthetic fast-ion loss detector and imaging heavy ion beam probe diagnostics in the 3D hybrid kinetic-MHD code MEGA
(American Institute of Physics, 2021-04-27)
A synthetic fast-ion loss (FIL) detector and an imaging Heavy Ion Beam Probe (i-HIBP) have been implemented in the 3D hybrid kinetic-magnetohydrodynamic code MEGA. First synthetic measurements from these two diagnostics ...

I-mode studies at ASDEX Upgrade: L-I and I-H transitions, pedestal and confinement properties
(IOP Publishing, 2017)
The I-mode is a plasma regime obtained when the usual L-H power threshold is high, e.g. with unfavourable ion B ∇ direction. It is characterised by the development of a temperature pedestal while the density remains ...

Dynamics of the pedestal transport during edge localized mode cycles at ASDEX Upgrade
(IOP Publishing, 2020)
The dynamic behaviour of the ion and electron energy, particle and momentum transport measured during type-I edge localized mode (ELM) cycles at ASDEX Upgrade is presented. Fast measurements of the ion and electron temperature ...

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. ...
