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.

Feedback system for divertor impurity seeding based on real-time measurements of surface heat flux in the Alcator C-Mod tokamak [PDF]

, 2016
Mitigation of the intense heat flux to the divertor is one of the outstanding problems in fusion energy. One technique that has shown promise is impurity seeding, i.e., the injection of low-Z gaseous impurities (typically N2 or Ne) to radiate and ...

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 ...

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.

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.

Observation of the significant reductions of electron density and electron temperature in a cascaded arc high density argon plasma with ammonia seeding comparing with nitrogen seeding by laser Thomson scattering approach

Nuclear Materials and Energy, 2022
In this work, the influences of ammonia (NH3) seeding on the electron density (ne) and electron temperature (Te) in a high-density cascaded arc argon plasma have been investigated by laser Thomson scattering. As NH3 seeding ratio increases from 0% to 2%,
