Recent Developments in Bayesian Inference of Tokamak Plasma Equilibria and High-Dimensional Stochastic Quadratures

G. T. von Nessi, M. J. Hole

We present recent results and technical breakthroughs for the Bayesian inference of tokamak equilibria using force-balance as a prior constraint. Issues surrounding model parameter…

Using Bayesian Analysis and Gaussian Processes to Infer Electron Temperature and Density Profiles on the MAST Experiment

G. T. von Nessi, M. J. Hole

A unified, Bayesian inference of midplane electron temperature and density profiles using both Thompson scattering (TS) and interferometric data is presented. Beyond the Bayesian n…

Computation of multi-region relaxed magnetohydrodynamic equilibria

S. R. Hudson, R. L. Dewar, G. Dennis +4

We describe the construction of stepped-pressure equilibria as extrema of a multi-region, relaxed magnetohydrodynamic (MHD) energy functional that combines elements of ideal MHD an…

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…

Hamilton--Jacobi theory for continuation of magnetic field across a toroidal surface supporting a plasma pressure discontinuity

M. McGann, S. R. Hudson, R. L. Dewar +1

The vanishing of the divergence of the total stress tensor (magnetic plus kinetic) in a neighborhood of an equilibrium plasma containing a toroidal surface of discontinuity gives b…

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…
