Accelerated Bayesian inference of plasma profiles with self-consistent MHD equilibria at W7-X via neural networks

Andrea Merlo, Andrea Pavone, Daniel Böckenhoff +10

High- operations require a fast and robust inference of plasma parameters with a self-consistent MHD equilibrium. Precalculated MHD equilibria are usually employe…

Proof of concept of a fast surrogate model of the VMEC code via neural networks in Wendelstein 7-X scenarios

Andrea Merlo, Daniel Böckenhoff, Jonathan Schilling +7

In magnetic confinement fusion research, the achievement of high plasma pressure is key to reaching the goal of net energy production. The magnetohydrodynamic (MHD) model is used t…

Bayesian modelling of multiple plasma diagnostics at Wendelstein 7-X

Sehyun Kwak, J. Svensson, S. Bozhenkov +7

Consistent inference of the electron density and temperature has been carried out with multiple heterogeneous plasma diagnostic data sets at Wendelstein 7-X. The predictive models…

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…

Deep learning for Gaussian process tomography model selection using the ASDEX Upgrade SXR system

Francisco Matos, Jakob Svensson, Andrea Pavone +2

Gaussian process tomography (GPT) is a method used for obtaining real-time tomographic reconstructions of the plasma emissivity profile in a tokamak, given some model for the under…

Optimisation of out-vessel magnetic diagnostics for plasma boundary reconstruction in tokamaks

J. A. Romero, J. Svensson

To improve the low frequency spectrum of magnetic field measurements of future tokamak reactors such as ITER, several steady state magnetic sensor technologies have been considered…

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…
