EDGE2D-EIRENE simulations of the influence of isotope effects and anomalous transport coefficients on near scrape-off layer radial electric field
(IOP Publishing, 2019-04-04)
EDGE2D-EIRENE (the ‘code’) simulations show that radial electric field, Er, in the near scrape-off layer (SOL) of tokamaks can have large variations leading to a strong local E × B shear greatly exceeding that in the core ...

Progress in understanding disruptions triggered by massive gas injection via 3D non-linear MHD modelling with JOREK
(IOP Publishing, 2017-01)
3D non-linear MHD simulations of a D2 massive gas injection (MGI) triggered disruption in JET with the JOREK code provide results which are qualitatively consistent with experimental observations and shed light on the ...

Divertor currents optimization procedure for JET-ILW high flux expansion experiments
(Elsevier, 2018-04)
This paper deals with a divertor coil currents optimized procedure to design High Flux Expansion (HFE) configurations in the JET tokamak aimed to study the effects of flux expansion variation on the radiation fraction and ...

Structure, tritium depth profile and desorption from 'plasma-facing' beryllium materials of ITER-Like-Wall at JET
(Elsevier, 2017)
Tritium depth profile and its temperature programmed desorption rate were determined for selected samples cut out of beryllium tiles removed from the Joint European Torus vacuum vessel during the 2012 shut down. A beryllium ...

Overview of ASDEX Upgrade results
(IOP Publishing, 2017)
The ASDEX Upgrade (AUG) programme is directed towards physics input to critical elements of the ITER design and the preparation of ITER operation, as well as addressing physics issues for a future DEMO design. Since 2015, ...

First measurements of a scintillator-based fast-ion loss detector in reversed Ip/Bt at the ASDEX Upgrade tokamak
(Elsevier, 2023-08)
Fast-α losses in future fusion power plants are expected to follow the co- and counter-current directions due to the isotropy of the fusion reaction. At the ASDEX Upgrade tokamak, the co-current direction (achieved with ...

The effects of electron cyclotron heating and current drive on toroidal Alfven eigenmodes in tokamak plasmas
(IOP Publishing, 2018-01)
Dedicated studies performed for toroidal Alfvén eigenmodes (TAEs) in ASDEX-Upgrade (AUG) discharges with monotonic q-profiles have shown that electron cyclotron resonance heating (ECRH) can make TAEs more unstable. In ...

Assessment of erosion, deposition and fuel retention in the JET-ILW divertor from ion beam analysis data
(Elsevier, 2017-08)
Post-mortem analyses of individual components provide relevant information on plasma-surface interac- tions like tungsten erosion, beryllium deposition and plasma fuel retention with divertor tiles via implan- tation or ...

Fusion product losses due to fishbone instabilities in deuterium JET plasmas
(IOP Publishing, 2018-01)
During development of a high-performance hybrid scenario for future deuteriumtritium experiments on the Joint European Torus, an increased level of fast ion losses in the MeV energy range was observed during the instability ...
