The role of plasma-atom and molecule interactions on power \& particle balance during detachment on the MAST Upgrade Super-X divertor
Kevin Verhaegh, Bruce Lipschultz, James Harrison +12
This paper shows first quantitative analysis of the detachment processes in the MAST Upgrade Super-X divertor (SXD). We identify an unprecedented impact of plasma-molecular interac…
Power exhaust and core-divertor compatibility of the baffled snowflake divertor in TCV
Sophie Gorno, Claudia Colandrea, Olivier Février +8
A baffled Snowflake Minus Low-Field Side (SF-LFS) is geometrically-optimised in TCV, increasing divertor neutral pressure, to evaluate the roles of divertor closure (comparing with…
Improved Heat and Particle Flux Mitigation in High Core Confinement, Baffled, Alternate Divertor Configurations in the TCV tokamak
Harshita Raj, C. Theiler, A. Thornton +13
Nitrogen seeded detachment has been achieved in the Tokamak a Configuration Variable (TCV) in advanced divertor configurations (ADCs), namely X-divertor and X-point target, with an…
Spectroscopic investigations of detachment on the MAST Upgrade Super-X divertor
Kevin Verhaegh, Bruce Lipschultz, James Harrison +17
We present the first analysis of the atomic and molecular processes at play during detachment in the MAST-U Super-X divertor using divertor spectroscopy data. Our analysis indicate…
Comparison between MAST-U conventional and Super-X configurations through SOLPS-ITER modelling
Alexandre Fil, Bruce Lipschultz, David Moulton +5
MAST-U has recently started operating with a Super-X divertor, designed to increase total flux expansion and neutral trapping, both predicted through simple analytic models and SOL…
Quiescence near the X-point of MAST measured by high speed visible imaging
N. R. Walkden, J. Harrison, S. A. Silburn +5
Using high speed imaging of the divertor volume, the region close to the X-point in MAST is shown to be quiescent. This is confirmed by three different analysis techniques and the…
Overview of recent physics results from MAST
A Kirk, J Adamek, RJ Akers +160
New results from MAST are presented that focus on validating models in order to extrapolate to future devices. Measurements during start-up experiments have shown how the bulk ion…
L-mode filament characteristics on MAST as a function of plasma current measured using visible imaging
A. Kirk, A. J. Thornton, J. R. Harrison +2
Clear filamentary structures are observed at the edge of tokamak plasmas. These filaments are ejected out radially and carry plasma in the far Scrape Off Layer (SOL) region, where…
Modelling of spatial structure of divertor footprints caused by edge-localized modes mitigated by magnetic perturbations
Pavel Cahyna, Marina Becoulet, Guido T. A. Huijsmans +7
Resonant magnetic perturbations (RMPs) can mitigate the edge-localized modes (ELMs), i.e. cause a change of the ELM character towards smaller energy loss and higher frequency. Duri…
