Variational Formulation of a Hybrid Kinetic and Gyrokinetic Model for Astrophysical and Laboratory Plasmas
F. N. deOliveira-Lopes, S. C. Thatikonda, D. Told +5
The paper introduces a Lagrangian model that couples fully kinetic ions with gyrokinetic electrons to efficiently simulate solar‑wind electromagnetic turbulence, using variational…
Plasmoid formation via competing lower-hybrid drift and Kelvin-Helmholtz instabilities: A hybrid kinetic-gyrokinetic simulation study
S. Thatikonda, F. N. De Oliveira-Lopes, A. Mustonen +3
We investigate the nonlinear formation of plasmoids in 2D low-beta current sheets through the interplay between the Kelvin-Helmholtz instability (KHI) and the lower-hybrid drift in…
Verification of a hybrid gyrokinetic model using the advanced semi-Lagrange code ssV
Sreenivasa chary Thatikonda, F. N. De Oliveira-Lopes, A. Mustonen +3
The super simple Vlasov (ssV) code was developed to study instabilities, turbulence, and reconnection in weakly magnetized plasmas, such as the solar wind in the dissipation range…
Verification of the PICLS electromagnetic upgrade in mixed variables
Annika Stier, Alberto Bottino, David Coster +3
The gyrokinetic particle-in-cell code PICLS is a full-f finite element tool to simulate turbulence in the tokamak scrape-off layer. During the previous year, the capability of PICL…
Reduced kinetic modelling of shattered pellet injection in ASDEX Upgrade
Peter Halldestam, Paul Heinrich, Gergely Papp +8
Plasma-terminating disruptions represent a critical outstanding issue for reactor-relevant tokamaks. ITER will use shattered pellet injection (SPI) as its disruption mitigation sys…
