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…
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…
