Enhanced confinement in diverted negative-triangularity L-mode plasmas in TCV

Olivier Sauter, Stefano Coda, Benoît Labit, Laurie Porte, Alessandro Pau, Alessandro Marinoni, Antoine Pierre Emmanuel Alexis Merle, Umar Sheikh, Cedric Kar-Wai Tsui, Matteo Vallar

The favorable confinement properties of negative-triangularity (NT) tokamak configurations were discovered in the TCV tokamak in the late 1990s and were documented over the two following decades, through investigations of predominantly electron-heated plas ...

Progress from ASDEX Upgrade experiments in preparing the physics basis of ITER operation and DEMO scenario development

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

An overview of recent results obtained at the tokamak ASDEX Upgrade (AUG) is given. A work flow for predictive profile modelling of AUG discharges was established which is able to reproduce experimental H-mode plasma profiles based on engineering parameter ...

Performance of a high vacuum, high temperature compatible millimeter-range viewing dump for the vertical ECE experiment on TCV

Ambrogio Fasoli, Laurie Porte, Arsène Stéphane Tema Biwole

A high vacuum and high temperature compatible viewing dump, made of MACOR, was designed and installed in TCV for Vertical ECE experiments in the 75-110 GHz frequency range. Measurements of the dump prior to installation in the tokamak showed in more than 9 ...

High resolution density pedestal measurements during edge localized modes by short-pulse reflectometry in the TCV tokamak

Stefano Coda, Benoît Labit, Laurie Porte, Pedro Andres Molina Cabrera

This publication presents high spatio-temporal resolution (mm/μs) density profile measurements of the pedestal top during type I, III, and small edge localized mode (ELM) H- mode plasmas in the Tokamak à Configuration Variable (TCV). These measurements wer ...

Evolution of nitrogen concentration and ammonia production in N-2-seeded H-mode discharges at ASDEX Upgrade

Olivier Sauter, Stefano Coda, Basil Duval, Timothy Goodman, Federico Alberto Alfredo Felici, Cristian Sommariva, Laurie Porte, Antoine Pierre Emmanuel Alexis Merle, Haomin Sun, Richard Pitts

Ammonia formation was studied in a series of dedicated nitrogen seeded H-mode discharges at ASDEX Upgrade. The evolution of ammonia formation was investigated with a reference phase before the seeding, and a long, stable flat-top nitrogen-seeded phase. It ...

Investigation of the role of electron temperature gradient modes in electron heat transport in TCV plasmas

Olivier Sauter, Stephan Brunner, Laurie Porte, Alexander Karpushov, Alberto Mariani, Claudio Marini

Electron-scale micro-turbulence driven by the electron temperature gradient (ETG) instability has recently been shown to impact the electron heat transport in tokamaks. Given the relevance of these mechanisms for ITER scenarios, a new study has been carrie ...
