Effect of energetic ions on edge-localized modes in tokamak plasmas

Olivier Sauter, Stefano Coda, Timothy Goodman, Jean-Marc Moret, Duccio Testa, Patrick Blanchard, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Federico Alberto Alfredo Felici

The most efficient and promising operational regime for the International Thermonuclear Experimental Reactor tokamak is the high-confinement mode. In this regime, however, periodic relaxations of the plasma edge can occur. These edge-localized modes pose a ...

Overview of the EUROfusion Tokamak Exploitation programme in support of ITER and DEMO

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Jean-Marc Moret, Duccio Testa, Patrick Blanchard, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler

Within the 9th European Framework programme, since 2021 EUROfusion is operating five tokamaks under the auspices of a single Task Force called ‘Tokamak Exploitation’. The goal is to benefit from the complementary capabilities of each machine in a coordinat ...

Magnetic control of tokamak plasmas through deep reinforcement learning

Ambrogio Fasoli, Olivier Sauter, Basil Duval, Stefano Coda, Jean-Marc Moret, Federico Alberto Alfredo Felici, Cristian Sommariva, Antoine Pierre Emmanuel Alexis Merle, Cristian Galperti, Francesco Carpanese

Nuclear fusion using magnetic confinement, in particular in the tokamak configuration, is a promising path towards sustainable energy. A core challenge is to shape and maintain a high-temperature plasma within the tokamak vessel. This requires high-dimensi ...

Initial TCV operation with a baffled divertor

Ambrogio Fasoli, Holger Reimerdes, Basil Duval, Jean-Marc Moret, Duccio Testa, Patrick Blanchard, Christian Gabriel Theiler, Umar Sheikh, Matthieu Toussaint, Marcelo Baquero Ruiz

The Tokamak à Configuration Variable (TCV) tokamak is in the midst of an upgrade to further its capability to investigate conventional and alternative divertor configurations. To that end, modular and removable gas baffles have been installed to decrease t ...

TCV heating and divertor upgrades

Ambrogio Fasoli, Basil Duval, Jean-Marc Moret, Stefano Alberti, Holger Reimerdes, Christian Gabriel Theiler, Alexander Karpushov, Matthieu Toussaint, Marcelo Baquero Ruiz, Dario Vaccaro

The operational range and the reactor relevance of the TCV experiments are being enhanced by two sets of major upgrades. The first includes the installation of neutral beam injection (NBI) and new electron cyclotron (EC) auxiliary heating sources, to reach ...

First demonstration of real-time kinetic equilibrium reconstruction on TCV by coupling LIUQE and RAPTOR

Olivier Sauter, Jean-Marc Moret, Federico Alberto Alfredo Felici, Antoine Pierre Emmanuel Alexis Merle, Cristian Galperti, Francesco Carpanese

Kinetic equilibrium reconstruction (KER) in tokamaks is the solution of the free-boundary MHD equilibrium that best fits the external magnetic measurements and the internal plasma profiles as imposed from modeling and/or available internal measurements. In ...

Thermal, electromagnetic and structural analysis of gas baffles for the TCV divertor upgrade

Basil Duval, Matthieu Toussaint, Jean-Marc Moret, Dario Vaccaro, Holger Reimerdes, Christian Gabriel Theiler

As part of an ongoing divertor upgrade of the TCV tokamak it is planned to add gas baffles to form a divertor chamber of variable closure. The baffles promise to increase the compression of neutral particles in the divertor and, thereby, extend the researc ...

Control of NTMs and integrated multi-actuator plasma control on TCV

Olivier Sauter, Jean-Marc Moret, Federico Alberto Alfredo Felici, Antoine Pierre Emmanuel Alexis Merle, Cristian Galperti, Mengdi Kong, Francesco Carpanese, Anna Teplukhina, Federico Pesamosca, Emanuele Poli

The control of 2/1 neoclassical tearing modes (NTMs) with electron cyclotron (EC) waves has been studied both experimentally and numerically on TCV. Dynamic evolutions of NTMs along with time-varying deposition locations of the control beam have been studi ...
