Beryllium film deposition in cavity samples in remote areas of the JET divertor during the 2011-2012 ITER-like wall campaign
(Elsevier, 2017-08)
Beryllium film deposition was studied with cavity samples in remote areas of the inner and outer JET divertor and below divertor tile 5 during the 2011–2012 campaign with the ITER-like wall. Predominantly beryllium films ...

Modelling of the effect of ELMs on fuel retention at the bulk W divertor of JET
(Elsevier, 2019-05)
Effect of ELMs on fuel retention at the bulk W target of JET ITER-Like Wall was studied with multi-scale calculations. Plasma input parameters were taken from ELMy H-mode plasma experiment. The energetic intra-ELM fuel ...

Overview of the JET ITER-like wall divertor
(Elsevier, 2017-08)
The work presented draws on new analysis of components removed following the second JET ITER-like wall campaign 2013–14 concentrating on the upper inner divertor, inner and outer divertor corners, life- time issues relating ...

Deposition in the inner and outer corners of the JET divertor with carbon wall and metallic ITER-like wall
(IOP Publishing, 2016-02)
Rotating collectors and quartz microbalances (QMBs) are used in JET to provide time-dependent measurements of erosion and deposition. Rotation of collector discs behind apertures allows recording of the long term evolution ...

Fuel inventory and deposition in castellated structures in JET-ILW
(IOP Publishing, 2017-06)
Since 2011 the JET tokamak has been operated with a metal ITER-like wall (JET-ILW) including castellated beryllium limiters and lamellae-type bulk tungsten tiles in the divertor. This has allowed for a large scale test ...

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 ...

EDGE2D-EIRENE simulations of the impact of poloidal flux expansion on the radiative divertor performance in JET
(Elsevier, 2017)
In the past at JET, with the MkI divertor, a systematic study of the influence of X-point height and poloidal flux expansion has been conducted [1,2] showing minor differences in the radiation distribution, whereas in [3] ...

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 ...

First mirror test in JET for ITER: Complete overview after three ILW campaigns
(ELSEVIER, 2019-05-19)
The First Mirror Test for ITER has been carried out in JET with mirrors exposed during (1) the third IIW campaign (11.W-3, 2015-2016, 23.33 h plasma) and (ii) all three campaigns, Le LW1 to ILW-3: 20112016 63,52 h in total. ...
