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 ...

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 ...

Deposition of impurity metals during campaigns with the JET ITER-like Wall
(Elsevier, 2019-05-19)
Post mortem analysis shows that mid and high atomic number metallic impurities are present in deposits on JET plasma facing components with the highest amount of Ni and W, and therefore the largest sink, being found at the ...

Tritium distributions on W-coated divertor tiles used in the third JET ITER-like wall campaign
(Elsevier, 2019-01)
Tritium (T) distributions on tungsten (W)-coated plasma-facing tiles used in the third ITER-like wall campaign (2015-2016) of the Joint European Torus (JET) were examined by means of an imaging plate technique and beta-ray ...

Beryllium migration in JET ITER-like wall plasmas
(IOP Publishing, 2015)
JET is used as a test bed for ITER, to investigate beryllium migration which connects the lifetime of first-wall components under erosion with tokamak safety, in relation to long-term fuel retention. The (i) limiter and ...

Assessment of erosion, deposition and fuel retention in the JET-ILW divertor from ion beam analysis data
(Elsevier, 2017-08)
Post-mortem analyses of individual components provide relevant information on plasma-surface interac- tions like tungsten erosion, beryllium deposition and plasma fuel retention with divertor tiles via implan- tation or ...

Deuterium retention in the divertor tiles of JET ITER-Like wall
(Elsevier, 2019)
Tungsten-coated divertor tiles exposed during the third JET ITER-Like Wall (ILW) campaign in 2015–2016 (ILW3) were studied with Secondary Ion Mass Spectrometry (SIMS). ILW-3 campaign contained more high-power plasma ...
