Turbulent relaxation patterns in SOL plasma
R Varennes, G Dif-Pradalier, P Ghendrih +5
Relaxations of localized over-density in a plane transverse to the magnetic field are numericallyinvestigated under the effect of drift-wave and interchange drives in SOL condition…
Stable Deuterium-Tritium burning plasmas with improved confinement in the presence of energetic-ion instabilities
Jeronimo Garcia, Yevgen Kazakov, Rui Coelho +18
Providing stable and clean energy sources is a necessity for the increasing demands of humanity. Energy produced by fusion reactions, in particular in tokamaks, is a promising path…
Physics informed Neural Networks applied to the description of wave-particle resonance in kinetic simulations of fusion plasmas
Jai Kumar, David Zarzoso, Virginie Grandgirard +2
The Vlasov-Poisson system is employed in its reduced form version (1D1V) as a test bed for the applicability of Physics Informed Neural Network (PINN) to the wave-particle resonanc…
Optimizing beam-ion confinement in ITER by adjusting the toroidal phase of the 3-D magnetic fields applied for ELM control
L. Sanchis, M. Garcia-Munoz, E. Viezzer +8
The confinement of Neutral Beam Injection (NBI) particles in the presence of n=3 Resonant Magnetic Perturbations (RMPs) in 15 MA ITER DT plasmas has been studied using full orbit A…
Towards enhanced performance in fusion plasmas via turbulence suppression by MeV ions
S. Mazzi, J. Garcia, D. Zarzoso +9
Megaelectron volt (MeV) alpha particles will be the main source of plasma heating in magnetic confinement fusion reactors. Yet, instead of heating fuel ions, most of the energy of…
Basic microscopic plasma physics from N-body mechanics
Dominique Escande, Didier Bénisti, Yves Elskens +2
Computing is not understanding. This is exemplified by the multiple and discordant interpretations of Landau damping still present after seventy years. For long deemed impossible,…
Cross-code gyrokinetic verification and benchmark on the linear collisionless dynamics of the geodesic acoustic mode
A. Biancalani, A. Bottino, C. Ehrlacher +10
The linear properties of the geodesic acoustic modes (GAM) in tokamaks are investigated by means of the comparison of analytical theory and gyrokinetic numerical simulations. The d…
On seed island generation and the non-linear self-consistent interaction of the tearing mode with electromagnetic gyro-kinetic turbulence
William Hornsby, Pierluigi Migliano, Rico Buchholz +4
The multi-scale interaction of self-consistently driven magnetic islands with electromagnetic turbulence is studied within the three dimensional, toroidal gyro-kinetic framework. I…
The linear tearing instability in three dimensional, toroidal gyrokinetic simulations
William Hornsby, Pierluigi Migliano, Rico Bucholz +5
Linear gyro-kinetic simulations of the classical tearing mode in three-dimensional toroidal geometry were performed using the global gyro kinetic turbulence code, GKW . The results…
Nonlinear seed island generation by three-dimensional electromagnetic, gyrokinetic turbulence
William Hornsby, Pierluigi Migliano, Rico Buchholz +4
Turbulence is shown to be critical to the onset and evolution of the neoclassical tearing mode, affecting both its growth and rotation. The interaction is here studied for the firs…
Numerical validation of the electromagnetic gyrokinetic code NEMORB on global axisymmetric modes
Alessandro Biancalani, Alberto Bottino, Philipp Lauber +1
This is a report about a comparison of collisionless simulations on global modes (i.e. low poloidal mode number) with gyrokinetic code NEMORB against analytical theory and other co…
Accuracy of unperturbed motion of particles in a gyrokinetic semi-Lagrangian code
Guillaume Latu, Virginie Grandgirard, Jérémie Abiteboul +9
Inaccurate description of the equilibrium can yield to spurious effects in gyrokinetic turbulence simulations. Also, the Vlasov solver and time integration schemes impact the conse…
Observation of confined current ribbon in JET plasmas
E. R. Solano, P. J. Lomas, B. Alper +29
we report the identification of a localised current structure inside the JET plasma. It is a field aligned closed helical ribbon, carrying current in the same direction as the back…
