EFD-C(13)04/05 Divertor Stray Light Analysis in JET-ILW and Implications for the H-£ Diagnostic in ITER

, 2013
We report on the first results for the spectrum of divertor stray light (DSL) and the signal to background ratio for D-alpha light emitted from the far SOL and divertor in JET in the recent ITERlike wall (ILW) campaign.

Progress in reducing ICRF-specific impurity release in ASDEX upgrade and JET

Nuclear Materials and Energy, 2017
Use of new 3-strap ICRF antennas with all-tungsten (W) limiters in ASDEX Upgrade results in a reduction of the W sources at the antenna limiters and of the W content in the confined plasma by at least a factor of 2 compared to the W-limiter 2-strap ...

COREDIV modelling of JET ILW discharges with different impurity seeding: nitrogen, neon, argon and krypton

Nukleonika, 2017
Numerical simulations with the COREDIV code of JET H-mode discharges with 25 MW of auxiliary heating in the ITER-like wall (ILW) configuration with different impurity seedings – nitrogen (N), neon (Ne), argon (Ar) and krypton (Kr) – are presented.

Inter-ELM evolution of the edge current density in JET-ILW type I ELMy H-mode plasmas [PDF]

, 2018
Recent studies (Maggi et al 2015 Nucl. Fusion 55 113031; Maggi et al 2017 Nucl. Fusion 57 116012) have shown that on JET with the Be/W ITER-like wall (JET-ILW) in high beta discharges with high D-2 gas rates, the inter-ELM temperature pedestal growth is ...

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.

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 ...
