A graphical pipeline platform for MRS data processing and analysis: MRSpecLAB

Matthias Hugues Jörg Kockisch, Lijing Xin, Mark Stephan Widmaier, Ying Xiao, Zhiwei Huang, Antonia Kaiser, André Döring, Robin Carlet, Xinyu Liu

Magnetic resonance spectroscopy (MRS) and magnetic resonance spectroscopic imaging (MRSI), are non-invasive techniques used to quantify biochemical compounds in tissue, such as choline, creatine, glutamate, glutamine, γ-aminobutyric acid, N-acetylaspartate ...

Psep/PLH control in deuterium and deuterium-tritium JET plasmas

Olivier Sauter, Alessandro Pau

The high confinement mode (H-mode) is a promising route to achieve high performance tokamak operations, as the ones foreseen in ITER and beyond. However, accessing a stable H-mode phase requires that the power across the plasma separatrix, Psep, exceeds a ...

Meta-Substituted Asymmetric Azobenzenes: Insights into Structure-Property Relationship

Tatiana Antonova Pachova, Giuseppe Sforazzini

This article presents a comprehensive investigation into the functionalization of methoxyphenylazobenzene using electron-directing groups located at the meta position relative to the azo group. Spectroscopic analysis of meta-functionalized azobenzenes reve ...

Experiments and SOLEDGE3X modeling of dissipative divertor and X-point Radiator regimes in WEST

Holger Reimerdes

X-Point Radiator (XPR) regimes have been obtained in WEST tokamak experiments with nitrogen seeding during the experimental campaigns of 2023 and 2024. These experiments showed the formation of a stable toroidal radiating ring near the X-point, similar to ...

Analysis techniques for blob properties from gas puff imaging data

Christian Gabriel Theiler, Curdin Tobias Wüthrich, Nicola Offeddu, Guillaume Raphäel Hervé Van Parys

Filamentary structures, also known as blobs, are a prominent feature of turbulence and transport at the edge of magnetically confined plasmas. They cause cross-field particle and energy transport and are, therefore, of interest in tokamak physics and, more ...

Stability analysis of alpha driven toroidal Alfven eigenmodes observed in JET deuterium-tritium internal transport barrier plasmas

Paulo Giovane Paschoali Pereira Puglia

A toroidal Alfven eigenmode (TAE) has been observed to be driven by alpha particles in a JET deuterium-tritium internal transport barrier plasma. The observation occurred 50 ms after the removal of neutral beam heating (NBI). The mode is observed on magnet ...

Development of a Collisional Radiative Model for Hydrogen-Cesium Plasmas and Its Application to SPIDER

Basile Marie Jacques Pouradier Duteil

SPIDER is the full scale prototype for the ITER Heating Neutral Beam (HNB) source. The production of negative ions in the source mostly relies on the conversion of H/D atoms and positive ions on a 1.6 m x 0.8 m converter surface, which is covered with cesi ...

Enhanced performance in fusion plasmas through turbulence suppression by megaelectronvolt ions

Samuele Mazzi

Alpha particles with energies on the order of megaelectronvolts will be the main source of plasma heating in future magnetic confinement fusion reactors. Instead of heating fuel ions, most of the energy of alpha particles is transferred to electrons in the ...

Divertor closure effects on the TCV boundary plasma

Basil Duval, Benoît Labit, Holger Reimerdes, Christian Gabriel Theiler, Umar Sheikh, Claudia Colandrea, Lorenzo Martinelli, Sri Harsha Kasi Raj

The Tokamak a Configuration Variable (TCV) has recently been equipped with gas baffles to increase its divertor closure for a broad range of divertor magnetic geometries. First experimental results reported in Reimerdes et al. (2021) demonstrated compatibi ...

Scaling of the energy confinement time with beta and collisionality approaching ITER conditions

Yves Martin

The condition of the latest version of the ELMy H-mode database has been re-examined. It is shown that there is bias in the ordinary least squares regression for some of the variables. To address these shortcomings three different techniques are employed: ...
