Modelling of sawtooth-induced fast ion transport in positive and negative triangularity in TCV
Olivier Sauter, Basil Duval, Duccio Testa, Alexander Karpushov, Mario Ludovico Podesta, Antoine Pierre Emmanuel Alexis Merle, Marcelo Baquero Ruiz, Dmytry Mykytchuk, Matteo Vallar, Lorenzo Stipani
Internal kinks are a common magneto hydro-dynamic (MHD) instability observed in tokamak operation when the q profile in the plasma core is close to unity. This MHD instability impacts both the transport of the bulk plasma (current, particle and energy tran ...
IOP Publishing Ltd2022A Fast Ion Loss Detector for the TCV Tokamak
A Fast Ion Loss Detector (FILD) was designed, assembled, installed and commissioned for TCV. This is a radially positionable, scintillator based detector that provides information on the 2D fast-ion velocity space lost at the probe's location. The collecte ...
EPFL2021Observation of Alfvén Eigenmodes driven by off-axis neutral beam injection in the TCV tokamak
Olivier Sauter, Basil Duval, Duccio Testa, Alexander Karpushov, Marcelo Baquero Ruiz, Matteo Vallar, Claudio Marini, Filippo Bagnato, Lorenzo Stipani
Fast-particle driven Alfv´en Eigenmodes have been observed in low-collisionality discharges with off-axis neutral beam injection (NBI), electron cyclotron resonance heating (ECRH) and a reduced toroidal magnetic field. During NBI and ECRH, toroidicity indu ...
2020Determination of the Fast-Ion Phase-Space Coverage for the FILD Spatial Array of the ASDEX Upgrade Tokamak
The fast-ion phase-space coverage of the ASDEX Upgrade Fast-Ion Loss Detectors (FILD) has been estimated and the results are presented here. To that end, a numerical tool has been developed to determine particle orbits that can be accepted by each detector ...
2019LTCC magnetic sensors at EPFL and TCV: Lessons learnt for ITER
Duccio Testa, Xavier Llobet, Matthieu Toussaint, Pierre Lavanchy, Ugo Siravo, Frédéric Dolizy, Steve Couturier, Severino Antonioni, Christian Moura, Jonathan Bryan Lister, Thomas Maeder, Philippe Marmillod, Caroline Jacq, Blaise Marlétaz, Aylwin Iantchenko, Lorenzo Stipani, Adrien Aymeric Thibault Corne, Matthias Garcin
Innovative 3D high-frequency magnetic sensors have been designed and manufactured in-house for installation on the Tokamak a Configuration Variable (TCV), and are currently routinely operational. These sensors combine the Low Temperature Co-fired Ceramic ( ...
