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, Henri Weisen, Alessandro Pau, Mikhail Maslov, Cristian Sommariva, Federico Nespoli, Richard Pitts, David Pfefferlé, Yann Camenen, Jonathan Marc Philippe Faustin, Jan Horacek, Hamish William Patten, Javier García Hernández, Samuel Lanthaler, Marco Wischmeier, Nicola Vianello, Yao Zhou, Davide Galassi, Antonio José Pereira de Figueiredo, Liang Yao, Dalziel Joseph Wilson, 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 ...

Simulation of neutron emission in neutral beam injection heated plasmas with the real-time code RABBIT

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

In plasmas heated with deuterium beams a deficit of the expected fusion neutron rate is an indicator of the deterioration of the fast-ion confinement, caused, for instance, by magnetohydrodynamic instabilities. The capability of predicting this deficit dur ...

MHD Stability and Energy Principle for Two-Dimensional Equilibria without Assumption of Nested Magnetic Surfaces

Laurent Villard, Andrei Martynov

Abandoning the assumption of nested magnetic surfaces in tokamak plasma expands the field of research and opens up new approaches for both theoretical and experimental plasma physics. The computer code KINX for calculations of the ideal MHD stability was d ...

Realistic multi-machine tokamak profile simulations and numerical ramp-down optimization using the RAPTOR code

Anna Teplukhina

Predictive modelling of plasma profiles is an essential part of ongoing research in tokamak plasmas, required for a successful realization of future fusion reactors. This thesis focuses on upgrading the RAPTOR code to extend the area of its applicability f ...

Losses of runaway electrons in MHD-active plasmas of the COMPASS tokamak

Cristian Sommariva, Joan Decker, Gergely Papp

The significant role of magnetic perturbations in mitigation and losses of runaway electrons (REs) was documented in dedicated experimental studies of RE at the COMPASS tokamak. REs in COMPASS are produced both in low density quiescent discharges and in di ...

Generalised zonal modes in stationary axisymmetric plasmas

Jonathan Graves

The MHD model enables derivation and analysis of the rich structure of geodesic acoustic modes (GAMs) and zonal modes in axisymmetric magnetic confined plasmas. The modes are identifiable from a single dispersion relation as two branches of slow magnetoson ...

Conceptual design of the EU DEMO EC-system: main developments and R&D achievements

Stefano Alberti, Minh Quang Tran, Falk Hans Braunmüller, Ioannis Pagonakis, Emanuele Poli, Konstantinos Avramidis

For the development of a DEMOnstration Fusion Power Plant the design of auxiliary heating systems is a key activity in order to achieve controlled burning plasma. The present heating mix considers electron cyclotron resonance heating (ECRH), neutral beam i ...
