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…
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…
PoPe (Projection on Proper elements) for code control: verification, numerical convergence and reduced models. Application to plasma turbulence simulations
T Cartier-Michaud, P Ghendrih, Y Sarazin +9
The Projection on Proper elements (PoPe) is a novel method of code control dedicated to 1) checking the correct implementation of models, 2) determining the convergence of numerica…
