Initial observations in X-point target divertor discharges on MAST-U
N. Lonigro, K. Verhaegh, J. Harrison +14
The first high-power (> 3 MW) H-mode experiments using a double-null X-point-target (XPT) divertor configuration have been performed on MAST-U. The XPT geometry is obtained by comb…
Evolution of radiation profiles in a strongly baffled divertor on MAST Upgrade
Fabio Federici, Matthew L. Reinke, Bruce Lipschultz +11
Plasma detachment involves interactions of the plasma with impurities and neutral particles, leading to significant losses of plasma power, momentum, and particles. Accurate mappin…
Effect of detachment on Magnum-PSI ELM-like pulses: I. Direct observations and qualitative results
Fabio Federici, Bruce Lipschultz, Gijs R. A. Akkermans +4
Conditions similar to those at the end of the divertor leg in a tokamak were replicated in the linear plasma machine Magnum-PSI. The neutral pressure in the target chamber is then…
Effect of detachment on Magnum-PSI ELM-like pulses: II. Spectroscopic analysis and role of molecular assisted reactions
Fabio Federici, Bruce Lipschultz, Gijs R. A. Akkermans +6
The linear plasma machine Magnum-PSI can replicate similar conditions to those found in a tokamak at the end of the divertor leg. A dedicated capacitor bank, in parallel to the pla…
Divertor shaping with neutral baffling as a solution to the tokamak power exhaust challenge
K. Verhaegh, J. R. Harrison, D. Moulton +20
Exhausting power from the hot fusion core to the plasma-facing components is one of the biggest challenges in fusion energy. The MAST Upgrade tokamak uniquely integrates strong con…
Investigations of atomic \& molecular processes of NBI-heated discharges in the MAST Upgrade Super-X divertor with implications for reactors
K. Verhaegh, J. R. Harrison, B. Lipschultz +20
This experimental study presents an in-depth investigation of the performance of the MAST-U Super-X divertor during NBI-heated operation (up to 2.5 MW) focussing on volumetric ion…
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…
The role of plasma-molecule interactions on power and particle balance during detachment on the TCV tokamak
Kevin Verhaegh, Bruce Lipschultz, James Harrison +14
This paper shows experimental results from the TCV tokamak that indicate plasma-molecule interactions involving and possibly play an important role as sinks of energy…
A novel hydrogenic spectroscopic technique for inferring the role of plasma-molecule interaction on power and particle balance during detached conditions
K Verhaegh, B Lipschultz, C Bowman +13
Detachment, an important mechanism for reducing target heat deposition, is achieved through reductions in power, particle and momentum; which are induced through plasma-atom and pl…
