Two-dimensional inference of divertor plasma characteristics: advancements to a multi-instrument Bayesian analysis system

Autor: Greenhouse, Daniel, Bowman, Chris, Lipschultz, Bruce, Verhaegh, Kevin, Harrison, James, Fil, Alexandre

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 tokamak divertors. Tests of the divertor multi-instrument Bayesian analysis

Report

Investigating the impact of the molecular charge-exchange rate on detached SOLPS-ITER simulations

Autor: Verhaegh, Kevin, Williams, Aelwyn C, Moulton, David, Lipschultz, Bruce, Duval, Basil P., Fevrier, Olivier, Fil, Alexandre, Osborne, Nick, Reimerdes, Holger, Theiler, Christian

Plasma-molecular interactions generate molecular ions which react with the plasma and contribute to detachment through molecular activated recombination (MAR), reducing the ion target flux, and molecular activated dissociation (MAD), both of which cr

Spectroscopic investigations of detachment on the MAST Upgrade Super-X divertor

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 indicates detachment in the MAST-U Super-X divertor can be separated into four

Report

Comparison between MAST-U conventional and Super-X configurations through SOLPS-ITER modelling

Autor: Fil, Alexandre, Lipschultz, Bruce, Moulton, David, Thornton, Andrew, Dudson, Ben, Myatra, Omkar, Verhaegh, Kevin, team, EUROFusion MST1

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 SOLPS calculations to reduce the plasma and impurity density detachment t

The process of divertor detachment, whereby heat and particle fluxes to divertor surfaces are strongly diminished, is required to reduce heat loading and erosion in a magnetic fusion reactor to acceptable levels. In this paper the physics leading to

Modeling of massive gas injection triggered disruptions in tokamak plasmas

Autor: Fil, Alexandre

Les disruptions du plasma sont des phénomènes se produisant dans les tokamaks et qui entraînent une perte totale du confinement du plasma et la fin de la décharge. Ces disruptions sont des phénomènes rapides et violents et peuvent endommager le
