Plasma-neutral collision operators for hydrogen isotopes: kinetic and gyrokinetic descriptions, comparison to fluid
Matthieu Protais, Guilhem Dif-Pradalier, Yanick Sarazin +4
Plasma-neutral interactions critically affect the edge dynamics of magnetically confined fusion devices. Neutral atoms modify ion and electron velocity distributions, potentially a…
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…
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…
The Problem of Marginality in Model Reductions of Turbulence
C. Gillot, G. Dif-Pradalier, Y. Sarazin +8
Reduced quasilinear (QL) and nonlinear (gradient-driven) models with scale separations, commonly used to interpret experiments and to forecast turbulent transport levels in magneti…
Transport barrier onset and edge turbulence shortfall in fusion plasmas
Guilhem Dif-Pradalier, Philippe Ghendrih, Yanick Sarazin +7
Turbulent plasmas notably self-organize to higher energy states upon application of additional free energy sources or modification of edge operating conditions. Mechanisms whereby…
Targeting realistic geometry in Tokamak code Gysela
Nicolas Bouzat, Camilla Bressan, Virginie Grandgirard +2
In magnetically confined plasmas used in Tokamak, turbulence is responsible for specific transport that limits the performance of this kind of reactors. Gyrokinetic simulations are…
