Phase dynamics and locking of large-scale modes in plasma edge
Paper in proceeding, 2024
The dynamic of local and non-local phase locking of large-scale modes
leading to edge-localized modes (ELMs) are analyzed from the simulation
data with the non-linear extended MHD code JOREK [1,2,3].
Phases are not stochastic as assumed in the Random Phase Approximation
(RPA) models, and in contrast, the non-linear couplings result in the
locking of the phases with non-local features.
It is observed that the mode with the highest growth rate leading to an
ELM crash, goes though a phase locking phase as the energy of the mode
increases, followed by a phase mixing after the crash.
