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…
2D electron density profile evolution during detachment in Super-X divertor L-mode discharges on MAST-U
N. Lonigro, R. S. Doyle, K. Verhaegh +12
2D electron density profiles obtained from coherence imaging spectroscopy in different MAST-U divertor conditions are compared. The data includes variations of strike point positio…
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…
Simulating the Impact of Baffling on Divertor Performance Using SOLPS-ITER
Cyd Cowley, David Moulton, Bruce Lipschultz
Strong divertor baffling is a feature expected to have a number of advantages for core-edge integration in tokamaks, yet one which requires much more detailed and extensive study.…
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…
Bayesian Analysis of Conventional and Ultrafast Spectroscopy Data for Investigating Detachment in the MAST-Upgrade Super-X
Xander Pope, Kevin Verhaegh, Chris Bowman +1
This paper presents the application, testing and first results of a new adaptive Bayesian inference analysis which utilises conventional and ultrafast spectroscopic measurements ma…
First 2D electron density measurements using Coherence Imaging Spectroscopy in the MAST-U Super-X divertor
N. Lonigro, R. Doyle, J. S. Allcock +11
2D profiles of electron density and neutral temperature are inferred from multi-delay Coherence Imaging Spectroscopy data of divertor plasmas using a non-linear inversion technique…
Two-dimensional inference of divertor plasma characteristics: advancements to a multi-instrument Bayesian analysis system
Daniel Greenhouse, Chris Bowman, Bruce Lipschultz +3
An integrated data analysis system based on Bayesian inference has been developed for application to data from multiple diagnostics over the two-dimensional cross-section of tokama…
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…
Interpretation of scrape-off layer profile evolution and first-wall ion flux statistics on JET using a stochastic framework based on filamentary motion
N. R. Walkden, A. Wynn, F. Militello +6
This paper presents the use of a novel modelling technique based around intermittent transport due to filament motion, to interpret experimental profile and fluctuation data in the…
