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 ...

Mixed hydrogen-deuterium plasmas on JET ILW
(IOP Publishing, 2020)
A study of mixed hydrogen-deuterium H-mode plasmas has been carried out in JET-ILW to strengthen the physics basis for extrapolations to JET D-T operation and to support the development of strategies for isotope ratio ...

Divertor, scrape-off layer and pedestal particle dynamics in the ELM cycle on ASDEX Upgrade
(IOP Publishing, 2018)
In addition to the relaxation of the pedestal, edge localised modes (ELMs) introduce changes to the divertor and scrape-off layer (SOL) conditions. Their impact on the inter-ELM pedestal recovery is investigated, with ...

Comparative H-mode density limit studies in JET and AUG
(Elsevier, 2017-08)
Identification of the mechanisms for the H-mode density limit in machines with fully metallic walls, and their scaling to future devices is essential to find for these machines the optimal operational boundaries with the ...

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 ...

Analysis of ELM stability with extended MHD models in JET, JT-60U and future JT-60SA tokamak plasmas
(IOP Publishing, 2018-01)
The stability with respect to a peeling–ballooning mode (PBM) was investigated numerically with extended MHD simulation codes in JET, JT-60U and future JT-60SA plasmas. The MINERVA-DI code was used to analyze the linear ...

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 ...

I-mode studies at ASDEX Upgrade: L-I and I-H transitions, pedestal and confinement properties
(IOP Publishing, 2017)
The I-mode is a plasma regime obtained when the usual L-H power threshold is high, e.g. with unfavourable ion B ∇ direction. It is characterised by the development of a temperature pedestal while the density remains ...

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 ...

Possible influence of near SOL plasma on the H-mode power threshold
(Elsevier, 2017)
A strong effect of divertor configuration on the threshold power for the L-H transition (P LH ) was observed in recent JET experiments in the new ITER-like Wall (ILW) [1–3] . Following a series of EDGE2D-EIRENE code ...
