How eigenmode self-interaction affects zonal flows and convergence of tokamak core turbulence with toroidal system size

Stephan Brunner, Gabriele Merlo, Justin Richard Ball, Julien Stanislas Pierre Dominski, Ajay Chandrarajan Jayalekshmi

Self-interaction is the process by which a microinstability eigenmode that is extended along the direction parallel to the magnetic field interacts non-linearly with itself. This effect is particularly significant in gyrokinetic simulations accounting for ...
