Modelling of tungsten erosion and deposition in the divertor of JET-ILW in comparison to experimental findings
(Elsevier, 2019-01)
The erosion, transport and deposition of tungsten in the outer divertor of JET-ILW has been studied for an H-Mode discharge with low frequency ELMs. For this specific case with an inter-ELM electron temperature at the ...

Overview of the JET results in support to ITER
(IOP Publishing, 2017)
The 2014–2016 JET results are reviewed in the light of their significance for optimising the ITER research plan for the active and non-active operation. More than 60 h of plasma operation with ITER first wall materials ...

The global build-up to intrinsic edge localized mode bursts seen in divertor full flux loops in JET
(AIP Publishing, 2015-07)
A global signature of the build-up to an intrinsic edge localized mode (ELM) is found in the temporal analytic phase of signals measured in full flux azimuthal loops in the divertor region of JET. Toroidally integrating, ...

Overview of the TCV tokamak experimental programme
(IOP Publishing, 2022)
The tokamak à configuration variable (TCV) continues to leverage its unique shaping capabilities, flexible heating systems and modern control system to address critical issues in preparation for ITER and a fusion power ...

Conceptual design of a scintillator based Imaging Heavy Ion Beam Probe for the ASDEX Upgrade tokamak
(Institute of Physics Publishing, 2017)
A conceptual design of a new diagnostic for the simultaneous space and time resolved measurement of plasma density, potential and poloidal magnetic field fluctuations at ASDEX Upgrade is proposed. The diagnostic combines ...

First measurements of a magnetically driven fast-ion loss detector on ASDEX Upgrade
(Institute of Physics Publishing, 2019)
A new scintillator-based fast-ion loss detector (FILD) has been deployed ∼45ˆ below the midplane of the ASDEX Upgrade tokamak. Port unavailability at this remote location requires an in-situ magnetically driven manipulator ...

Fast ion transport during applied 3D magnetic perturbations on DIII-D
(IOP Publishing, 2015-07)
Measurements show fast ion losses correlated with applied three-dimensional (3D) fields in a variety of plasmas ranging from L-mode to resonant magnetic perturbation (RMP) edge localized mode (ELM) suppressed H-mode ...

High-resolution tungsten spectroscopy relevant to the diagnostic of high-temperature tokamak plasmas
(2018-05)
The x-ray transitions in Cu- and Ni-like tungsten ions in the 5.19–5.26 A wavelength range that are relevant ˚ as a high-temperature tokamak diagnostic, in particular for JET in the ITER-like wall configuration, have been ...

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 ...

Identification of BeO and BeOxDy in melted zones of the JET Be limiter tiles: Raman study using comparison with laboratory samples
(Elsevier, 2018-12)
Beryllium oxide (BeO) and deuteroxide (BeOxDy) have been found on the melted zone of a beryllium tile extracted from the upper dump plate of JET-ILW (2011-2012 campaign). Results have been obtained using Raman microscopy, ...
