Isotope effects in linear and saturated ohmic confinement of TCV tokamak and gyrokinetic validation

Olivier Sauter, Basil Duval, Stefano Coda, Benoît Labit, Alexander Karpushov, Artur Perek, Oleg Krutkin, Dmytry Mykytchuk, Henri Weisen, Lorenzo Martinelli

We investigated isotope effects during the tokamak à configuration variable (TCV) ohmic discharge of a diverted positive triangular shape configuration of deuterium (D) and hydrogen (H) plasmas. The transition from the linear ohmic confinement (LOC) regime ...

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 ...

The quasi-continuous exhaust regime in JET

Olivier Sauter, Benoît Labit

The quasi-continuous exhaust (QCE) regime is a regime that is naturally type-I ELM-free. It combines the high density at the plasma edge needed for power exhaust with the high normalised energy confinement typical for H-mode operation. In the QCE regime la ...

Progress in Pedestal and Edge Physics: Chapter 3 of the Special Issue: on the Path to Tokamak Burning Plasma Operation

Benoît Labit, Umar Sheikh

This paper describes the extensive progress that has been made in the understanding of tokamak pedestal physics since the 2007 publication of 'Progress in the ITER Physics Basis' (Ikeda 2007 Nucl. Fusion 47 E01-S500). It serves as Chapter 3 of the 2025 Nuc ...

L-H power threshold for neutral beam heated plasmas with Deuterium, Hydrogen, Helium and mixed ion species in TCV

Olivier Sauter, Basil Duval, Yves Martin, Benoît Labit, Alessandro Pau, Alexander Karpushov, Artur Perek, Dmytry Mykytchuk

A systematic study of the power threshold for L-H transition has been conducted in TCV. Only results from NB heated plasmas are reported. The dependencies of PLH on plasma current, plasma density and main ion species have been investigated. For Deuterium&# ...

Helium plasma operations on ASDEX Upgrade and JET in support of the non-nuclear phases of ITER

Benoît Labit

For its initial operational phase, ITER has until recently considered using non-nuclear hydrogen (H) or helium (He) plasmas to keep nuclear activation at low levels. To this end, the Tokamak Exploitation Task Force of the EUROfusion Consortium carried out ...

Progress in the development of the ITER baseline scenario in TCV

Olivier Sauter, Stefano Coda, Benoît Labit, Alessandro Pau, Alexander Karpushov, Antoine Pierre Emmanuel Alexis Merle, Oleg Krutkin, Cassandre Ekta Contré, Reinart Andreas J. Coosemans, Yann Camenen

Under the auspices of EUROfusion, the ITER baseline (IBL) scenario has been jointly investigated on AUG and TCV in the past years and this paper reports on the developments on TCV. It is found that the performance of TCV IBL is mainly limited by (neoclassi ...

Study of impurity C transport and plasma rotation in negative triangularity on the TCV tokamak

Olivier Sauter, Basil Duval, Stefano Coda, Benoît Labit, Alessandro Pau, Laurie Porte, Alexander Karpushov, Antoine Pierre Emmanuel Alexis Merle, Justin Richard Ball, Dmytry Mykytchuk

Carbon impurity transport is studied in the TCV tokamak using a charge exchange recombination diagnostic. TCVs flexible shaping capabilities were exploited to extend previous impurity transport studies to negative triangularity (delta < 0). A practical way ...

Observation of magnetic islands in tokamak plasmas during the suppression of edge-localized modes

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Benoît Labit, Alessandro Pau, Federico Alberto Alfredo Felici, Cristian Sommariva, Laurie Porte, Antoine Pierre Emmanuel Alexis Merle

In tokamaks, a leading platform for fusion energy, periodic filamentary plasma eruptions known as edge-localized modes occur in plasmas with high-energy confinement and steep pressure profiles at the plasma edge. These edge-localized modes could damage the ...

Investigation of intrinsic error fields in MAST-U device

Benoît Labit

In magnetic fusion devices, undesired non-axisymmetric magnetic field perturbations, typically called error fields (EF), have been observed to have a detrimental effect on plasma stability and confinement and can lead to brute plasma terminations, i.e. pla ...
