Investigation of deuterium trapping and release in the JET divertor during the third ILW campaign using TDS
(Elsevier, 2019-05)
Selected set of samples from JET ITER-Like Wall (JET-ILW) divertor tiles exposed in 2015–2016 has been analysed using Thermal Desorption Spectrometry (TDS). The deuterium (D) amounts obtained with TDS were compared with ...

Beam modelling and hardware design of an imaging heavy ion beam probe for ASDEX Upgrade
(IOP Publishing, 2019)
The imaging heavy ion beam probe (i-HIBP) developed at the ASDEX Upgrade tokamak is a new diagnostic concept for investigations at the edge of high temperature plasmas. By means of a heavy alkali beam injector, a neutral ...

Beam-Ion Acceleration during Edge Localized Modes in the ASDEX Upgrade Tokamak
(American Physical Society, 2018-07)
The acceleration of beam ions during edge localized modes (ELMs) in a tokamak is observed for the first time through direct measurements of fast-ion losses in low collisionality plasmas. The accelerated beamion population ...

Isotope identity experiments in JET-ILW with H and D L-mode plasmas
(IOP Publishing, 2019-06-07)
NBI-heated L-mode plasmas have been obtained in JET with the Be/W ITER-like wall (JETILW) in H and D, with matched profiles of the dimensionless plasma parameters, ρ* , ν* , β and q in the plasma core confinement region ...

Fast-ion redistribution and loss due to edge perturbations in the ASDEX Upgrade, DIII-D and KSTAR tokamaks
(IOP Publishing, 2013)
The impact of edge localized modes (ELMs) and externally applied resonant and non-resonant magnetic perturbations (MPs) on fast-ion confinement/transport have been investigated in the ASDEX Upgrade (AUG), DIII-D and KSTAR ...

Feasibility study for an edge main ion charge exchange recombination spectroscopy system at ASDEX Upgrade
(IOP Publishing, 2019)
A feasibility study for a new edge main ion charge exchange recombination spectroscopy (CXRS) system at the ASDEX Upgrade tokamak has been carried out. This diagnostic uses the new edge fast-ion Dα (FIDA) spectrometers and ...

Velocity-space sensitivity and tomography of scintillator-based fast-ion loss detectors
(IOP Publishing, 2018)
A simple model for the instrument function of scintillator-based fast-ion loss detectors (FILD) has been developed which accounts for the orbit trajectories in the 3D detector geometry and for the scintillator response. ...

Imaging neutral particle analyzer for fast-ion transport measurements in the ASDEX upgrade tokamak
(2024-03-19)
In future fusion reactors, suprathermal particles (fast ions, FI) will play a key role in the generation of fusion power as they are an important source of energy (heating) and momentum (current drive). A loss of their ...

Magnetic equilibrium design for the SMART tokamak
(Elsevier Ltd, 2021)
The SMall Aspect Ratio Tokamak (SMART) device is a new compact (plasma major radius Rgeo≥0.40 m, minor radius a≥0.20 m, aspect ratio A≥1.7) spherical tokamak, currently in development at the University of Seville. The SMART ...
