Measurements of heat flux components due to charged and non-charged particles in DIII-D divertor near and under detachment

Nuclear Materials and Energy, 2023
Surfacing Eroding Thermocouples (SETC) have been used to provide high spatial and temporal resolution heat flux measurement in DIII-D. SETCs were first tested in the lower divertor of DIII-D using the Divertor Material Evaluation System (DiMES), then an ...

Control of tungsten impurity source and edge transport using different gas injection with full tungsten divertor on EAST

Nuclear Materials and Energy, 2022
Tungsten (W) erosion and edge transport are investigated for EAST L-mode discharges with different gas injection. It is found that W erosion can be suppressed or mitigated by Ne or D2 seeding when divertor detachment is achieved.

Optimizing detachment control using the magnetic configuration of divertors [PDF]

Nuclear Fusion, 2022
Abstract As tokamak research moves to reactor conditions, the control of a stable, optimally-detached divertor plasma has become increasingly relevant. Simple predictions of such detachment control have been performed previously using the detachment location sensitivity (DLS) model (Lipschultz et al 2016 Nucl.

Modeling of argon seeding in ASDEX Upgrade H-mode plasma with SOLPS5.0

Nuclear Materials and Energy, 2017
SOLPS modeling of Ar seeding in ASDEX Upgrade H-mode plasma shows that the divertor compression of Ar increases with the seeding rate when the inner divertor is detached and the outer divertor is attached.

A new scaling for divertor detachment

Plasma Physics and Controlled Fusion, 2017
Abstract The ITER design, and future reactor designs, depend on divertor ‘detachment,’ whether partial, pronounced or complete, to limit heat flux to plasma-facing components and to limit surface erosion due to sputtering.

Sustained radiative divertor in high-performance grassy-ELM regime with metal wall towards long-pulse operation in EAST

Nuclear Materials and Energy, 2021
Simultaneous control of transient heat load induced by large-amplitude edge-localized modes (ELMs) and steady-state heat load on divertor targets under metal wall environment is crucial for steady-state operation of future tokamak fusion reactors, such ...
