Beryllium global erosion and deposition at JET-ILW simulated with ERO2.0
(Elsevier, 2019-01)
The recently developed Monte-Carlo code ERO2.0 is applied to the modelling of limited and diverted discharges at JET with the ITER-like wall (ILW). The global beryllium (Be) erosion and deposition is simulated and compared ...

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 ...

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 ...

Improved ERO modelling for spectroscopy of physically and chemically assisted eroded beryllium from the JET-ILW
(Elsevier, 2016-12)
Physical and chemical assisted physical sputtering were characterised by the Be I and Be II line and BeD band emission in the observation chord measuring the sightline integrated emission in front of the inner beryllium ...

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 ...

First ERO2.0 modeling of Be erosion and non-local transport in JET ITER-like wall
(IOP Publishing, 2017-12)
ERO is a Monte-Carlo code for modeling plasma-wall interaction and 3D plasma impurity transport for applications in fusion research. The code has undergone a significant upgrade (ERO2.0) which allows increasing the ...

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 ...

Improved ERO modelling of beryllium erosion at ITER upper first wall panel using JET-ILW and PISCES-B experience
(Elsevier, 2019-05)
ERO is a 3D Monte-Carlo impurity transport and plasma-surface interaction code. In 2011 it was applied for the ITER first wall (FW) life time predictions [1] (critical blanket module BM11). After that the same code was ...

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 ...
