Patrick Blanchard, Timothy Goodman, Jean-Marc Moret, Olivier Sauter, Holger Reimerdes, Stefano Coda, Alexander Karpushov, Yanis Andrebe, Duccio Testa, Benoît Labit, Christian Gabriel Theiler, Federico Alberto Alfredo Felici, Hugo De Oliveira, Claudio Marini, Antoine Pierre Emmanuel Alexis Merle, Anna Teplukhina, Joan Decker, Cedric Kar-Wai Tsui, Umar Sheikh, Cristian Galperti, Kevin Henricus Annemarie Verhaegh, Dahye Choi, Aylwin Iantchenko, Mengdi Kong, Roberto Maurizio, Francesco Carpanese, Mirko Wensing, Lorenzo Stipani, Federico Pesamosca, Olivier Claude Martin Février, Filippo Bagnato, Cristian Sommariva, Davide Galassi

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 ...

Modelling of sawtooth-induced fast ion transport in positive and negative triangularity in TCV

Basil Duval, Olivier Sauter, Alexander Karpushov, Mario Ludovico Podesta, Duccio Testa, Antoine Pierre Emmanuel Alexis Merle, Marcelo Baquero Ruiz, Lorenzo Stipani, Matteo Vallar, Dmytry Mykytchuk

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 ...

A Fast Ion Loss Detector for the TCV Tokamak

Lorenzo Stipani

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 ...

Determination of the Fast-Ion Phase-Space Coverage for the FILD Spatial Array of the ASDEX Upgrade Tokamak

Lorenzo Stipani

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 ...
