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 ...

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 ...

Comparison of the structure of the plasma-facing surface and tritium accumulation in beryllium tiles from JET ILW campaigns 2011-2012 and 2013-2014
(ELSEVIER, 2019-05)
In this study, beryllium tiles from Joint European Torus (JET) vacuum vessel wall were analysed and compared regarding their position in the vacuum vessel and differences in the exploitation conditions during two cam paigns ...

An analytical expression for ion velocities at the wall including the sheath electric field and surface biasing for erosion modeling at JET ILW
(Elsevier, 2017)
For simulation of plasma-facing component erosion in fusion experiments, an analytical expression for the ion velocity just before the surface impact including the local electric field and an optional surface biasing effect ...

Studies of dust from JET with the ITER-Like Wall: Composition and internal structure
(Elsevier, 2017)
Results are presented for the dust survey performed at JET after the second experimental campaign with the ITER-Like Wall: 2013–2014. Samples were collected on adhesive stickers from several different posi- tions in the ...

Structure, tritium depth profile and desorption from 'plasma-facing' beryllium materials of ITER-Like-Wall at JET
(Elsevier, 2017)
Tritium depth profile and its temperature programmed desorption rate were determined for selected samples cut out of beryllium tiles removed from the Joint European Torus vacuum vessel during the 2012 shut down. A beryllium ...

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 ...

An improved model for the accurate calculation of parallel heat fluxes at the JET bulk tungsten outer divertor
(Elsevier, 2018-10)
Parallel heat flux calculations at the JET divertor have been based on the assumption that all incoming heat is due to the projection of the heat flux parallel to the magnetic line, q , plus a constant background. This ...
