Nitronic 50 Steel as a Structural Material for EU-DEMO's Toroidal Field Coils

Kamil Sedlák, Xabier Sarasola Martin, Jack Richard Greenwood

We report the results of an exploratory design study for Nitronic 50 (N50) Toroidal Field (TF) coils for the EU-DEMO fusion power plant. N50 is a super-austenitic steel that has a yield stress (𝝈 𝒚) of up to 1500 MPa at 4 K, 50% higher than the conventiona ...

Test results of the DTT poloidal field conductor samples in SULTAN: DC and AC characterization

Kamil Sedlák, Mattia Ortino, Hugues Marie Alain Bajas

The poloidal field (PF) magnet system of the Divertor Tokamak Test (DTT) facility consists of 6 superconducting coils with full top-down symmetry, realized in Nb3Sn (PF1 and PF6) and NbTi (PF2, PF3, PF4 and PF5). To validate the NbTi PF coil design, short ...

Radiation asymmetry in JET disruption mitigation experiments with shattered pellet injection

Mengdi Kong

In ITER, to mitigate the deleterious effects of plasma disruptions, massive quantities of radiating impurities will be injected into the disrupting plasma by shattered pellet injectors (SPI) to pre-emptively radiate away the stored thermal and magnetic ene ...

Parametric Studies of the EU DEMO Central Solenoid

Pierluigi Bruzzone, Kamil Sedlák, Xabier Sarasola Martin

The Central Solenoid (CS) is at the core of the EU DEMO tokamak, and has a strong impact on the tokamak design and the overall machine size. By ramping its current, the CS generates a change of magnetic flux, which initiates the plasma, and induces and con ...

Gyrokinetic particle-in-cell simulations of electromagnetic turbulence in the presence of fast particles and global modes

Laurent Villard, Emmanuel Lanti

Global simulations of electromagnetic turbulence in circular-flux-surface tokamak and ASDEX-Upgrade geometry, tearing instabilities and their combination with the electromagnetic turbulence, nonlinear Alfvenic modes in the presence of fast particles and th ...

Cross-field and parallel dynamics of SOL filaments in TCV

Basil Duval, Christian Gabriel Theiler, Davide Galassi, Curdin Tobias Wüthrich, Nicola Offeddu, Diego Sales de Oliveira

Using recently installed scrape-off layer diagnostics on the tokamak a configuration variable, we characterise the poloidal and parallel properties of turbulent filaments. We access both attached and detached divertor conditions across a wide range of core ...
