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

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 ...

Efficient single-stage optimization of islands in finite-β stellarator equilibria

Joaquim Loizu Cisquella, Erol Balkovic, Christopher Berg Smiet

We present single-stage optimization of islands in finite- β stellarator equilibria. Stellarator optimization is traditionally performed as a two-stage process; in the first stage, an optimal equilibrium is calculated that balances a set of competing const ...

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 ...

The core-edge integrated neon-seeded scenario in deuterium-tritium at JET

Michele Marin

This paper reports the first experiment carried out in deuterium-tritium addressing the integration of a radiative divertor for heat-load control with good confinement. Neon seeding was carried out for the first time in a D-T plasma as part of the second D ...

Analysis techniques for blob properties from gas puff imaging data

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

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 ...

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 ...

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: ...
