Plasma turbulence simulations in a diverted tokamak with applied resonant magnetic perturbations

Paolo Ricci, Joaquim Loizu Cisquella, Théophile Boinnard, António João Caeiro Heitor Coelho

The first results of three-dimensional, flux-driven, electrostatic, global, two-fluid turbulence simulations of a diverted tokamak configuration with applied resonant magnetic perturbations generated by a set of saddle coils are presented. The simulations ...

Development of free-boundary equilibrium and transport solvers for simulation and real-time interpretation of tokamak experiments

Francesco Carpanese

To exploit fusion as a source of energy, a hot and dense confined plasma is needed. This is achieved in tokamaks by actively controlling the plasma state meaning shape, position and internal kinetic profiles. This thesis addresses two topics: the developme ...

A wall-aligned grid generator for non-linear simulations of MHD instabilities in tokamak plasmas

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Jonathan Graves, Yves Martin, Duccio Testa, Patrick Blanchard, Alessandro Pau, Cristian Sommariva, Henri Weisen, Richard Pitts, Yann Camenen, Jan Horacek, Javier García Hernández, Marco Wischmeier, Nicola Vianello, Mikhail Maslov, Federico Nespoli, Yao Zhou, David Pfefferlé, Davide Galassi, Antonio José Pereira de Figueiredo, Jonathan Marc Philippe Faustin, Liang Yao, Dalziel Joseph Wilson, Hamish William Patten, Samuel Lanthaler, Bernhard Sieglin, Otto Asunta

Block-structured mesh generation techniques have been well addressed in the CFD community for automobile and aerospace studies, and their applicability to magnetic fusion is highly relevant, due to the complexity of the plasma-facing wall structures inside ...

Effects of 3D Ideal MHD Equilibrium Geometry on Neoclassical Properties in Tokamaks: Exploring Bootstrap Current and Impurity Accumulation

Madhusudan Raghunathan

This thesis concentrates on investigating the presence of 3D ideal MHD instabilities, particularly a saturated 1/1 ideal internal kink, on neoclassical phenomena such as the bootstrap current and heavy impurity transport. The MHD equilibria are generated u ...

Overview of the RFX-mod fusion science activity

Yi Zhang, Wilfred Anthony Cooper, Federico Alberto Alfredo Felici, Nicola Vianello, Matteo Vallar, Leonardo Pigatto, Elena Gaio, Alberto Ferro

This paper reports the main recent results of the RFX-mod fusion science activity. The RFX-mod device is characterized by a unique flexibility in terms of accessible magnetic configurations. Axisymmetric and helically shaped reversed-field pinch equilibria ...

Simulation of bootstrap current in 2D and 3D ideal magnetic fields in tokamaks

Olivier Sauter, Jonathan Graves, Wilfred Anthony Cooper, Madhusudan Raghunathan, Michael Pedro

We aim to simulate the bootstrap current for a MAST-like spherical tokamak using two approaches for magnetic equilibria including externally caused 3D effects such as resonant magnetic perturbations (RMPs), the effect of toroidal ripple, and intrinsic 3D e ...

Neoclassical toroidal torque generation by auxiliary heating in non-axisymmetric tori

Olivier Sauter

In conditions of ideal axisymmetry, for a magnetized plasma in a generic bounded domain, necessarily toroidal, the uniform absorption of external energy (e.g. rf or isotropic alpha heating) clearly cannot give rise to net forces or torques. A rather common ...

Overview of the RFX-mod contribution to the international Fusion Science Program

Wilfred Anthony Cooper, Nicola Vianello, Leonardo Pigatto, Elena Gaio, Alberto Ferro

The RFX-mod device is operated both as a reversed field pinch (RFP), where advanced regimes featuring helical shape develop, and as a tokamak. Due to its flexibility, RFX-mod is contributing to the solution of key issues in the roadmap to ITER and DEMO, in ...

Impact of RMP magnetic field simulation models on fast ion losses

Jonathan Graves, Wilfred Anthony Cooper, David Pfefferlé, Cyril Misev

Two opposing approaches to include resonant magnetic perturbations (RMPs) in fast ion simulations are compared, one where the vacuum field caused by the RMP current coils is added to the axisymmetric MHD equilibrium, the other where the MHD equilibrium inc ...
