Challenges in the extrapolation from DD to DT plasmas: experimental analysis and theory based predictions for JET-DT
(IOP Publishing, 2017-01)
A strong modelling program has been started in support of the future JET-DT campaign with the aim of guiding experiments in deuterium (D) towards maximizing fusion energy production in Deuterium–Tritium (DT). Some of the ...

Comparison of runaway electron generation parameters in small, medium-sized and large tokamaks-A survey of experiments in COMPASS, TCV, ASDEX-Upgrade and JET
(IOP Publishing, 2018-01)
This paper presents a survey of the experiments on runaway electrons (RE) carried out recently in frames of EUROFusion Consortium in different tokamaks: COMPASS, ASDEXUpgrade, TCV and JET. Massive gas injection (MGI) has ...

Multi-machine scaling of the main SOL parallel heat flux width in tokamak limiter plasmas
(IOP Publishing, 2016-07)
As in many of today’s tokamaks, plasma start-up in ITER will be performed in limiter configuration on either the inner or outer midplane first wall (FW). The massive, beryllium armored ITER FW panels are toroidally shaped ...

Deposition in the inner and outer corners of the JET divertor with carbon wall and metallic ITER-like wall
(IOP Publishing, 2016-02)
Rotating collectors and quartz microbalances (QMBs) are used in JET to provide time-dependent measurements of erosion and deposition. Rotation of collector discs behind apertures allows recording of the long term evolution ...

Evaluation of impurity densities from charge exchange recombination spectroscopy measurements at ASDEX Upgrade
(Institute of Physics Publishing, 2018-07-26)
At ASDEX upgrade (AUG) a new framework for the evaluation of impurity densities based on measurements from charge exchange recombination spectroscopy (CXRS) diagnostics has been developed. The charge exchange impurity ...

Scrape-off Layer Transport and Filament Characteristics in High-density Tokamak Regimes
(Institute of Physics Publishing, 2020)
A detailed cross-device investigation on the role of filamentary dynamics in high-density regimes has been performed within the EUROfusion framework, comparing the ASDEX Upgrade (AUG) and TCV tokamaks. Both devices run ...

L to H mode transition: parametric dependencies of the temperature threshold
(IOP Publishing, 2015-07)
The L to H mode transition occurs at a critical power which depends on various parameters, such as the magnetic field, the density, etc. Experimental evidence on various tokamaks (JET, ASDEX-Upgrade, DIII-D, Alcator C-Mod) ...

The I-mode confinement regime at ASDEX Upgrade: global propert ies and characterization of strongly intermittent density fluctuations
(IOP Publishing, 2017)
Properties of the Imode confinement regime on the ASDEX Upgrade tokamak are summarized. A weak dependence of the power threshold for the LI transition on the toroidal magnetic field strength is found. During improved ...

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 ...
