Gyrokinetic simulation of low-n Alfvenic modes in tokamak HL-2A plasmas
Javier García Hernández, Samuele Mazzi
The turbulence characteristics of plasmas with internal transport barriers in the HL-2A tokamak are analyzed by means of linear gyrokinetic simulations. It is found that turbulence is dominated by the ion temperature gradient (ITG) mode together with large ...
2023The role of isotope mass and transport for H-mode access in tritium containing plasmas at JET with ITER-like wall
Haomin Sun, Henri Weisen, Javier García Hernández, Marco Wischmeier, Nicola Vianello, Mikhail Maslov
The required heating power, P-LH, to access the high confinement regime (H-mode) in tritium containing plasmas is investigated in JET with ITER-like wall at a toroidal magnetic field of B-t = 1.8 T and a plasma current of I-p = 1.7 MA. PLH, also referred t ...
IOP Publishing Ltd2023A model of non-Maxwellian electron distribution function for the analysis of ECE data in JET discharges
Javier García Hernández, Mikhail Maslov, Samuele Mazzi
Recent experiments performed in JET at high level of plasma heating, in preparation of, and during the DT campaign have shown significant discrepancies between electron temperature measurements by Thomson Scattering (TS) and Electron Cyclotron Emission (EC ...
E D P SCIENCES2023The need for a unified European hydropower voice
Anton Schleiss, Javier García Hernández
The new EU proect ETIP Hydropower (September 2022 - August 2025) will closely link the EERA Joint Programme Hydropower to the new European Technology and Innovation Platform (ETIP) for hydropower. It succeeds the HYDROPOWER EUROPE project (2018-2022) which ...
2023Hint for a TeV neutrino emission from the Galactic Ridge with ANTARES
Javier García Hernández, Randoald Müller
Interactions of cosmic ray protons, atomic nuclei, and electrons in the interstellar medium in the inner part of the Milky Way produce γ-ray flux from the Galactic Ridge. If the γ-ray emission is dominated by proton and nuclei interactions, a neutrino flux ...
2023Study of fast-ion-driven toroidal Alfvén eigenmodes impacting on the global confinement in TCV L-mode plasmas
Stefano Coda, Laurent Villard, Stephan Brunner, Justin Richard Ball, Oleg Krutkin, Luke Simons, Umesh Kumar, Baruch Rofman, Jesús Poley Sanjuán, Javier García Hernández, Matteo Vallar, Aylwin Iantchenko, Samuele Mazzi
Following recent observations of unstable Toroidal Alfven Eigenmodes (TAEs) in a counter-current Neutral Beam Injection (NBI) scenario developed in TCV, an in-depth analysis of the impact of such modes on the global confinement and performance is carried o ...
2023Validation of D-T fusion power prediction capability against 2021 JET D-T experiments
Michele Marin, Javier García Hernández, Mikhail Maslov
JET experiments using the fuel mixture envisaged for fusion power plants, deuterium and tritium (D-T), provide a unique opportunity to validate existing D-T fusion power prediction capabilities in support of future device design and operation preparation. ...
Bristol2023JET D-T scenario with optimized non-thermal fusion
Haomin Sun, Michele Marin, Javier García Hernández, Mikhail Maslov
In JET deuterium-tritium (D-T) plasmas, the fusion power is produced through thermonuclear reactions and reactions between thermal ions and fast particles generated by neutral beam injection (NBI) heating or accelerated by electromagnetic wave heating in t ...
Bristol2023The JET hybrid scenario in Deuterium, Tritium and Deuterium-Tritium
Haomin Sun, Javier García Hernández, Mikhail Maslov, Matteo Fontana
The JET hybrid scenario has been developed from low plasma current carbon wall discharges to the record-breaking Deuterium-Tritium plasmas obtained in 2021 with the ITER-like Be/W wall. The development started in pure Deuterium with refinement of the plasm ...
Bristol2023Predictive modeling of Alfvén eigenmode stability in inductive scenarios in JT-60SA
Javier García Hernández, Antonio José Pereira de Figueiredo, Matteo Vallar
The JT-60SA device offers unique conditions before ITER for the study of the interaction of energetic particles with plasma waves. With similar dimensions to JET, e.g., a major radius but with a slightly more elongated plasma volume, JT-60SA is used as a h ...
