Determination of Be sputtering yields from the spectroscopic observations at JET ILW based on 3D ERO modelling [PDF]

, 2013
Estimations of the ITER first wall (FW) lifetime, previously made using the three-dimensional Monte-Carlo ERO code (Borodin et al 2011 Phys. Scr. T145 014008), depend strongly on the assumptions of the physical sputtering yield for beryllium (Be).

Main chamber wall plasma loads in JET-ITER-like wall at high radiated fraction

Nuclear Materials and Energy, 2017
Future tokamak reactors of conventional design will require high levels of exhaust power dissipation (more than 90% of the input power) if power densities at the divertor targets are to remain compatible with active cooling.

Beryllium Migration in JET ITER-like Wall Plasmas [PDF]

, 2014
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.

Density pedestal prediction model for tokamak plasmas

Nuclear Fusion
A model for the pedestal density prediction based on neutral penetration combined with pedestal transport is presented. The model is tested against a pedestal database of JET-ILW Type I ELMy H-modes showing good agreement over a wide range of parameters ...

Comparison of DIVIMP and EDGE2D-EIRENE tungsten transport predictions in JET edge plasmas

Nuclear Materials and Energy, 2020
The average tungsten concentrations in the pedestal region (cW) predicted by the Monte Carlo code DIVIMP and the coupled multi-fluid plasma/kinetic neutral code EDGE2D-EIRENE are found to agree within a factor of 2 for a range of JET-ILW L-mode and H ...

Testing for chaos in type-I ELM dynamics on JET with the ILW

, 2015
In H-mode plasmas, Edge Localized Modes are one of the main causes of the first wall erosion, especially in the divertor tiles. On the other hand, ELMs contribute to maintaining a stable plasma density, reducing the risks of disruptions ...
