Bayesian equilibria of axisymmetric plasmas
Sehyun Kwak, J. Svensson, O. Ford +3
We present a Bayesian method for inferring axisymmetric plasma equilibria from the magnetic field and plasma pressure measurements. The method calculates all possible solutions for…
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…
Overview of recent physics results from MAST
A Kirk, J Adamek, RJ Akers +160
New results from MAST are presented that focus on validating models in order to extrapolate to future devices. Measurements during start-up experiments have shown how the bulk ion…
Validation of equilibrium tools on the COMPASS tokamak
J. Urban, L. C. Appel, J. F. Artaud +5
Various MHD (magnetohydrodynamic) equilibrium tools, some of which being recently developed or considerably updated, are used on the COMPASS tokamak at IPP Prague. MHD equilibrium…
Evidence Cross-Validation and Bayesian Inference of MAST Plasma Equilibria
G. T. von Nessi, M. J. Hole, J. Svensson +1
In this paper, current profiles for plasma discharges on the Mega-Ampere Spherical Tokamak (MAST) are directly calculated from pickup coil, flux loop and Motional-Stark Effect (MSE…
Model Data Fusion: developing Bayesian inversion to constrain equilibrium and mode structure
M. J. Hole, G. von Nessi, J. Bertram +5
Recently, a new probabilistic "data fusion" framework based on Bayesian principles has been developed on JET and W7-AS. The Bayesian analysis framework folds in uncertainties and i…
