Sawtooth pacing with on-axis ICRH modulation in JET-ILW [PDF]

open access: yesNuclear Fusion, 2017
A novel technique for sawteeth control in tokamak plasmas using ion-cyclotron resonance heating (ICRH) has been developed in the JET-ILW tokamak [2].

The radiated power limit in impurity seeded JET-ILW plasmas

open access: yesNuclear Materials and Energy, 2022
The total radiated fraction is examined in high density H-mode plasmas (Greenwald fraction of about 85 %) in JET by the variation of the auxiliary heating power of Pheat = 14 MW-29 MW.

Pedestal structure, stability and scalings in JET-ILW: the EUROfusion JET-ILW pedestal database [PDF]

open access: yesNuclear Fusion, 2020
Abstract The EUROfusion JET-ILW pedestal database is described, with emphasis on three main issues. First, the technical aspects are introduced, including a description of the data selection, the datasets, the diagnostics used, the experimental and theoretical methods implemented and the main definitions.

Optimization of ICRH for core impurity control in JET-ILW [PDF]

open access: yesNuclear Fusion, 2016
Abstract Ion cyclotron resonance frequency (ICRF) heating has been an essential component in the development of high power H-mode scenarios in the Jet European Torus ITER-like wall (JET-ILW). The ICRF performance was improved by enhancing the antenna-plasma coupling with dedicated main chamber gas injection, including the preliminary ...

Density limit of H-mode plasmas on JET-ILW

open access: yesJournal of Nuclear Materials, 2015
High-density discharges on JET with ITER-like Wall (ILW) have been analysed with the aim of establishing a mechanism for the H-mode density limit (DL) and compared with experiments in the JET carbon material configuration. The density limit is up to 20% higher in the JET-ILW than in the JET-C machine. The observed H-mode density limit is found close to

Impact of W events and dust on JET-ILW operation [PDF]

open access: yesJournal of Nuclear Materials, 2015
The occurrence of transient impurity events (TIE) leading to intense radiation spikes in JET plasma discharges has been studied since the installation of the ITER-like wall (ILW). To generate the observed average increase in radiated power of 1.5 MW, a spherical particle of solid W of radius >90 μm would be required. The drop in plasma energy caused

Quartz micro-balance results of pulse-resolved erosion/deposition in the JET-ILW divertor [PDF]

open access: yesNuclear Materials and Energy, 2017
A set of quartz crystal microbalances (QMB) was used at JET with full carbon wall to monitor mass erosion/deposition rates in the remote areas of the divertor.

ICRH physics and technology achievements in JET-ILW [PDF]

open access: yesEPJ Web of Conferences, 2017
ICRH was extensively used in the 2015-16 JET-ILW (ITER like wall) experimental campaign; bulk heating together with high-Z impurity chase-out from plasma centre importantly contributed to the good DD fusion performance obtained recently in JET.

First mirror test in JET for ITER: Complete overview after three ILW campaigns

open access: yesNuclear Materials and Energy, 2019
The First Mirror Test for ITER has been carried out in JET with mirrors exposed during: (i) the third ILW campaign (ILW-3, 2015–2016, 23.33 h plasma) and (ii) all three campaigns, i.e. ILW-1 to ILW-3: 2011–2016, 63,52 h in total.
