ICRH system performance during ITER-Like Wall operations at JET and the outlook for DT campaign

EPJ Web of Conferences, 2017
Performance of JET ICRH system since installation of the metal ITER-Like Wall (ILW) has been assessed statistically. The data demonstrate steady increase of the RF power coupled to plasmas over recent years with the maximum pulse-average and peak values ...

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).

Tritium removal from JET-ILW after T and D–T experimental campaigns

Nuclear Fusion, 2023
After the second Deuterium–Tritium Campaign (DTE2) in the JET tokamak with the ITER-Like Wall (ILW) and full tritium campaigns that preceded and followed after the DTE2, a sequence of fuel recovery methods was applied to promote tritium removal from wall

Global and pedestal confinement in JET with a Be/W metallic wall

, 2014
Type I ELMy H-mode operation in JET with the ITER-like Be/W wall (JET-ILW) generally occurs at lower pedestal pressures compared to those with the full carbon wall (JET-C).

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.

An analytical expression for ion velocities at the wall including the sheath electric field and surface biasing for erosion modeling at JET ILW

Nuclear Materials and Energy, 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 is suggested.
