Multi-scale Interaction Mechanism for Edge-Localized-Mode Suppression in the Tokamak Edge [PDF]
Nature CommunicationsAbstract A central challenge in fusion energy is reconciling the high-confinement mode required for reactor performance with the intense intermittent relaxation events it produces, known as edge-localized modes. These instabilities arise in the steep pressure pedestal at the plasma edge when magnetohydrodynamic thresholds are crossed,

Electron temperature fluctuation levels of the quasi-coherent mode across the plasma radius [PDF]
EPJ Web of Conferences, 2023 EDA H-mode is an ELM-free regime in which the edge quasi-coherent mode (QCM) replaces the ELMs. The estimated location of the quasi-coherent mode is in a partly optically thin region of steep gradients localized between ρpol = 0.96 -1.

The Effect of Edge Mode on Mass Sensing for Strained Graphene Resonators
Micromachines, 2021 Edge mode could disturb the ultra-subtle mass detection for graphene resonators. Herein, classical molecular dynamics simulations are performed to investigate the effect of edge mode on mass sensing for a doubly clamped strained graphene resonator ...

Induced microwave scattering in the ITER edge transport barrier at ECRH and possibility of its modeling at ASDEX-Upgrade [PDF]
EPJ Web of Conferences, 2023 The induced scattering parametric decay instability of O-mode polarized microwaves leading to excitation of lower hybrid or electron plasma waves localized within a tokamak edge transport barrier is investigated.

Automatic identification of edge localized modes in the DIII-D tokamak
APL Machine Learning, 2023 Fusion power production in tokamaks uses discharge configurations that risk producing strong type I edge localized modes. The largest of these modes will likely increase impurities in the plasma and potentially damage plasma facing components, such as ...

Edge mode locality in perturbed symmetry protected topological order
SciPost Physics, 2019 Spin chains with symmetry-protected edge zero modes can be seen as prototypical systems for exploring topological signatures in quantum systems. These are useful for robustly encoding quantum information. However in an experimental realization of such

Kink–ballooning mode in circular tokamak plasma
AIP Advances, 2022 Peeling–ballooning modes, which are driven by gradients of parallel current and pressure in the pedestal, are widely accepted as the instability triggering large Edge Localized Modes (ELMs).

Inter-ELM pedestal localized fluctuations in tokamaks: Summary of multi-machine observations
Nuclear Materials and Energy, 2019 A variety of experimental studies on pedestal localized fluctuations appearing in between crashes of edge localized modes (ELMs) across several tokamaks have been reviewed and summarized.
