Reducing Turbulent Transport in Tokamaks by Combining Intrinsic Rotation and the Low Momentum Diffusivity Regime

Stephan Brunner, Justin Richard Ball, Haomin Sun

Based on the analysis of a large number of high-fidelity nonlinear gyrokinetic simulations, we propose a novel strategy to improve confinement in spherical tokamak plasmas by combining up-down asymmetric flux surface shaping with the Low Momentum Diffusivi ...

Investigation of triangularity effects on tokamak edge turbulence through multi-fidelity gyrokinetic simulations

Paolo Ricci, Antoine Cyril David Hoffmann, Alessandro Balestri

This paper uses the gyro-moment (GM) approach as a multi-fidelity tool to explore the effect of triangularity on tokamak edge turbulence. Considering experimental data from an L-mode DIII-D discharge, we conduct gyrokinetic (GK) simulations with realistic ...

Overview of T and D-T results in JET with ITER-like wall

Olivier Sauter, Holger Reimerdes, Duccio Testa, Benoît Labit, Umar Sheikh, Olivier Claude Martin Février, Eduardo José Lascas Neto, Cristian Sommariva, Alessandro Pau, Matteo Vallar, Gino Marceca, Cassandre Ekta Contré, Mackenzie Peter-Fulford Van Rossem, Samuele Mazzi, Carl Mathias Paul Hoppe

In 2021 JET exploited its unique capabilities to operate with T and D-T fuel with an ITER-like Be/W wall (JET-ILW). This second major JET D-T campaign (DTE2), after DTE1 in 1997, represented the culmination of a series of JET enhancements-new fusion diagno ...

Kinetic plasma-wall interaction using immersed boundary conditions

Emily Louise Bourne

The interaction between a plasma and a solid surface is studied in a (1D-1V) kinetic approach using immersed boundary conditions and penalization to model the wall. Two solutions for the penalized wall region are investigated that either allow currents to ...

The GBS code for the self-consistent simulation of plasma turbulence and kinetic neutral dynamics in the tokamak boundary

Gilles Fourestey, Paolo Ricci, Emmanuel Lanti, Nicolas Richart, Nicola Varini, Louis Nicolas Stenger, André Calado Coroado, Maurizio Giacomin, Davide Galassi, Davide Mancini

A new version of GBS (Ricci et al. (2012) [27]; Halpern et al. J. Comput. Phys. 315 (2016) 388-408; Paruta et al. (2018) [11]) is described. GBS is a three-dimensional, fluxdriven, global, two-fluid turbulence code developed for the self-consistent simulat ...

Progress in preparing real-time control schemes for Deuterium-Tritium operation in JET

Matteo Fontana, Alessandro Pau

Operation of a magnetic fusion experiment, such as JET, relies on the availability of real-time (RT) control schemes, which supervise the plasma as it approaches the expected target performance while maintaining the integrity of the machine and its subsyst ...

Effect of helium on irradiation-induced hardening of iron: A simulation point of view

Robin Schäublin

Irradiation-induced hardening and loss of ductility of ferritic/martensitic materials envisaged for future fusion reactor is still difficult to understand. In particular, helium (He), produced by transmutation by the fusion neutrons of 14 MeV, is known to ...
