3D simulations of gas puff effects on edge plasma and ICRF coupling in JET
(IOP Publishing, 2017-05)
Recent JET (ITER-Like Wall) experiments have shown that the fueling gas puffed from different locations of the vessel can result in different scrape-off layer (SOL) density profiles and therefore different radio frequency ...

Impact of the JET ITER-like wall on H-mode plasma fueling
(IOP Publishing, 2017-06)
JET ITER-like wall (ILW) experiments show that the edge density evolution is strongly linked with the poloidal distribution of the ionization source. The fueling profile in the JET-ILW is more delocalized as compared to ...

Power exhaust by SOL and pedestal radiation at ASDEX Upgrade and JET
(Elsevier, 2017)
Future fusion reactors require a safe, steady state divertor operation. A possible solution for the power exhaust challenge is the detached divertor operation in scenarios with high radiated power fractions. The radiation ...

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 ...

ELM divertor peak energy fluence scaling to ITER with data from JET, MAST and ASDEX upgrade
(Elsevier, 2017-08)
A newly established scaling of the ELM energy fluence using dedicated data sets from JET operation with CFC & ILW plasma facing components (PFCs), ASDEX Upgrade (AUG) operation with both CFC and full-W PFCs and MAST with ...

Analysis and design of the central stack for the SMART tokamak
(Elsevier, 2023)
The SMall Aspect Ratio Tokamak (SMART) is a new spherical machine that is currently under construction at the University of Seville aimed at exploring negative vs positive triangularity prospects in Spherical Tokamaks ...

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 ...
