Isotope mix effect on edge turbulent transport in pre-L–H transition conditions in JET-ILW

Nuclear Fusion
The heat flux at the edge of L-mode JET-ILW (Be wall and W divertor) pulses is studied using the gyrokinetic code Gyrokinetic Electromagnetic Numerical Experiment (GENE) in its flux-tube configuration as well as the quasi-linear turbulent transport model

Characterization of detachment inferred from the Balmer line ratios in JET-ILW low-confinement mode plasmas

Nuclear Materials and Energy
Spectroscopic measurements of the hydrogenic Balmer-α and Balmer-γ line emission in JET-ILW low-confinement mode (L-mode) deuterium plasmas are used to assess the onset of volume recombination in the low-field side (LFS) divertor.

Assessment of erosion, deposition and fuel retention in the JET-ILW divertor from ion beam analysis data

Nuclear Materials and Energy, 2017
Post-mortem analyses of individual components provide relevant information on plasma-surface interactions like tungsten erosion, beryllium deposition and plasma fuel retention with divertor tiles via implantation or co-deposition. Ion Beam techniques are

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

Nuclear 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 ...

Effect of density on peeling limited pedestals in JET-ILW, MAST-U and TCV and implications for ITER pedestal predictions

Nuclear Fusion
Plasmas with low collisionality and with the pedestal limited by peeling modes have been achieved in JET-ILW, MAST-U and TCV. The achieved electron–electron pedestal collisionality and the achieved ratio between electron separatrix density to pedestal ...
