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…
Magnetically confined charged particles: From steep density profiles to the breaking of the adiabatic invariant
Aurélien Cordonnier, Yohann Lebouazda, Xavier Leoncini +1
This study examines the stability of Vlasov equilibrium solutions for magnetically confined plasmas, derived through the principle of maximum entropy. By treating the toroidal limi…
Self-organisation through layering of -plane like turbulence in plasmas and geophysical fluids
P. L. Guillon, G. Dif-Pradalier, Y. Sarazin +2
Staircase formation and layering is studied in simplified, potential vorticity conserving models of plasmas and geophysical fluids, by investigating turbulent self-organisation and…
Flux-driven turbulent transport using penalisation in the Hasegawa-Wakatani system
Pierre L. Guillon, Özgür D. Gürcan, Guilhem Dif-Pradalier +2
First numerical results from the newly-developed pseudo-spectral code P-FLARE (Penalised FLux-driven Algorithm for REduced models) are presented. This flux-driven turbulence/transp…
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…
