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…
Investigating the impact of the molecular charge-exchange rate on detached SOLPS-ITER simulations
Kevin Verhaegh, Aelwyn C Williams, David Moulton +7
Plasma-molecular interactions generate molecular ions which react with the plasma and contribute to detachment through molecular activated recombination (MAR), reducing the ion tar…
Runaway dynamics in reactor-scale spherical tokamak disruptions
E. Berger, I. Pusztai, S. L. Newton +4
Understanding generation and mitigation of runaway electrons in disruptions is important for the safe operation of future tokamaks. In this paper we investigate runaway dynamics in…
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…
The JOREK non-linear extended MHD code and applications to large-scale instabilities and their control in magnetically confined fusion plasmas
M Hoelzl, GTA Huijsmans, SJP Pamela +50
JOREK is a massively parallel fully implicit non-linear extended MHD code for realistic tokamak X-point plasmas. It has become a widely used versatile code for studying large-scale…
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…
A study of the influence of plasma-molecule interactions on particle balance during detachment
K Verhaegh, B Lipschultz, J R Harrison +9
In this work we provide experimental insights into the impact of plasma-molecule interactions on the target ion flux decrease during divertor detachment achieved through a core den…
Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
Novel inferences of ionisation & recombination for particle/power balance during detached discharges using deuterium Balmer line spectroscopy
K. Verhaegh, B. Lipschultz, B. P. Duval +4
The physics of divertor detachment is determined by divertor power, particle and momentum balance. This work provides a novel analysis technique of the Balmer line series to obtain…
An improved understanding of the roles of atomic processes and power balance in divertor target ion current loss during detachment
Kevin Verhaegh, Bruce Lipschultz, Basil Duval +16
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 fusi…
Non-linear Simulations of MHD Instabilities in Tokamaks Including Eddy Current Effects and Perspectives for the Extension to Halo Currents
M. Hoelzl, G. T. A. Huijsmans, P. Merkel +9
The dynamics of large scale plasma instabilities can strongly be influenced by the mutual interaction with currents flowing in conducting vessel structures. Especially eddy current…
