Recent progress in the quantitative validation of JOREK simulations of ELMs in JET
(IOP Publishing, 2017-07)
Future devices like JT-60SA, ITER and DEMO require quantitative predictions of pedestal density and temperature levels, as well as inter-ELM and ELM divertor heat fluxes, in order to improve global confinement capabilities ...

Long-term fuel retention and release in JET ITER-Like Wall at ITER-relevant baking temperatures
(IOP Publishing, 2017-08)
The fuel outgassing efficiency from plasma-facing components exposed in JET-ILW has been studied at ITER-relevant baking temperatures. Samples retrieved from the W divertor and Be main chamber were annealed at 350 and ...

Determination of tungsten sources in the JET-ILW divertor by spectroscopic imaging in the presence of a strong plasma continuum
(Elsevier, 2019-01)
The identification of the sources of atomic tungsten and the measurement of their radiation distribution in front of all plasma-facing components has been performed in JET with the help of two digital cameras with the same ...

Tritium retention characteristics in dust particles in JET with ITER-like wall
(Elsevier, 2018-12)
A tritium imaging plate technique (TIPT) in combination with an electron-probe microscopic analysis (EPMA) were applied to examine tritium (T) retention characteristics in individual dust particles collected in the Joint ...

Dynamics and stability of divertor detachment in H-mode plasmas on JET
(IOP Publishing, 2017-09)
The dynamics and stability of divertor detachment in N2 seeded, type-I, ELMy H-mode plasmas with dominant NBI heating in the JET ITER-like wall device is studied by means of an integrated analysis of diagnostic data from ...

Real-time control of divertor detachment in H-mode with impurity seeding using Langmuir probe feedback in JET-ITER-like wall
(IOP Publishing, 2017-04)
Burning plasmas with 500 MW of fusion power on ITER will rely on partially detached divertor operation to keep target heat loads at manageable levels. Such divertor regimes will be maintained by a real-time control system ...

Impact of ICRF on the scrape-off layer and on plasma wall interactions: From present experiments to fusion reactor
(Elsevier, 2019-01)
Recent achievements in studies of the effects of ICRF (Ion Cyclotron Range of Frequencies) power on the SOL (Scrape-Off Layer) and PWI (Plasma WallInteractions) in ASDEX Upgrade (AUG),Alcator CMod,and JETIL Ware reviewed. ...

Characterisation of the deuterium recycling at the W divertor target plates in JET during steady-state plasma conditions and ELMs
(IOP Publishing, 2016-02)
Experiments in the JET tokamak equipped with the ITER-like wall (ILW) revealed that the inner and outer target plate at the location of the strike points represent after one year of operation intact tungsten (W) surfaces ...

Studies of the pedestal structure and inter-ELM pedestal evolution in JET with the ITER-like wall
(IOP Publishing, 2017-11)
The pedestal structure of type I ELMy H-modes has been analysed for JET with the ITERlike Wall (JET-ILW). The electron pressure pedestal width is independent of ρ* and increases proportionally to √βpol,PED. Additional ...

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 ...
