The radiated power limit in impurity seeded JET-ILW plasmas

Nuclear 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.

Effects of argon on deuterium retention in polycrystalline tungsten under single, sequential and simultaneous ion irradiation

Nuclear Materials and Energy, 2019
Argon is one of the candidates for impurity seeding in the ITER divertor; however, few studies exist on either Ar retention in W, or its effect on D retention in W.

Integration of high confinement, high poloidal beta plasma with dual radiated power and detachment controls for divertor protection and ELM suppression

Nuclear Materials and Energy, 2023
Divertor detachment without serious core confinement quality loss in DIII-D’s high poloidal β scenario has been combined with impurity-induced ELM mitigation without disruption.

Growth process of nano-tendril bundles with sputtered tungsten

Nuclear Materials and Energy, 2019
Nano-tendril bundles (NTBs) were generated in DC He plasma with impurity gas-seeding (Ne and N2) under sputtering-dominated conditions. NTB morphologies were characterized using the net erosion yield of samples.

Overview of the JET results in support to ITER [PDF]

, 2017
The 2014–2016 JET results are reviewed in the light of their significance for optimising the ITER research plan for the active and non-active operation. More than 60 h of plasma operation with ITER first wall materials successfully took place since its

Tungsten erosion and divertor leakage from the DIII-D SAS-VW tungsten-coated divertor in experiments with neon gas seeding

Nuclear Materials and Energy, 2023
Collector probes have been used to examine tungsten divertor leakage in a variety of scenarios with low-Z impurity seeding during operation with the new tungsten-coated SAS-VW divertor in DIII-D.

Corrigendum: Model-based impurity emission front control using deuterium fueling and nitrogen seeding in TCV (2023 Nucl. Fusion 63 026006)

Nuclear Fusion, 2023
In the published paper titled ‘Model-based impurity emission front control using deuterium fueling and nitrogen seeding in TCV’ (2023 Nucl. Fusion 63 026006), the legend of figure 5 shows the wrong colors: red and blue are switched.

High Vacuum Deposition of Biferrocene Thin Films on Room Temperature Substrates [PDF]

, 2017
: Metallocenes are a promising candidate for future spintronic devices due to their versatile and tunable magnetic properties. However, single metallocenes, e.g., ferrocene, sublimate below room temperature, and therefore the implementation for future ...

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.
