The H-mode Pedestal and Edge Localized Modes in NSTX [PDF]

, 2004
The research program of the National Spherical Torus Experiment (NSTX) routinely utilizes the H-mode confinement regime to test and extend beta and pulse length limits. As in conventional aspect ratio tokamaks, NSTX observes a variety of edge localized modes (ELMs) in H-mode. Hence a significant part of the research program is dedicated to ELMs studies.

Multi-scale Interaction Mechanism for Edge-Localized-Mode Suppression in the Tokamak Edge

Nature Communications
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.

Observation of magnetic islands in tokamak plasmas during the suppression of edge-localized modes [PDF]

In tokamaks, a leading platform for fusion energy, periodic filamentary plasma eruptions known as edge-localized modes occur in plasmas with high-energy confinement and steep pressure profiles at the plasma edge.

Parameter dependence of small Edge Localized Modes

, 2018
H-mode is the most promising candidate for the operation of future fusion devices. Its improved confinement comes along with periodically occurring edge localized modes (ELMs) which crash the edge transport barrier, degrade the pedestal and cause ...

Effect of energetic ions on edge-localized modes in tokamak plasmas [PDF]

The most efficient and promising operational regime for the International Thermonuclear Experimental Reactor tokamak is the high-confinement mode. In this regime, however, periodic relaxations of the plasma edge can occur. These edge-localized modes pose

Mechanism of phonon localized edge modes [PDF]

Physical Review B, 2010
The phonon localized edge modes are systematically studied, and two conditions are proposed for the existence of the localized edge modes: (I) coupling between different directions ($x$, $y$ or $z$) in the interaction; (II) different boundary conditions in three directions.

Edge Localized Modes in Tokamaks [PDF]

Fusion Science and Technology, 2008
As one increases the heating power in a tokamak beyond a threshold, the confinement undergoes a bifurcation, with a dramatic increase in the confinement time by a factor ˜2.

A survey on local transport mode detection on the edge of the network

Applied Intelligence, 2022
AbstractWe present a survey of smartphone-based Transport Mode Detection (TMD). We categorize TMD solutions into local and remote; the first ones are addressed in this article. A local approach performs the following steps in the smartphone (and not in some faraway cloud servers): 1) data collection or sensing, 2) preprocessing, 3) feature extraction ...

Local thermometry of neutral modes on the quantum Hall edge [PDF]

Nature Physics, 2012
A system of electrons in two dimensions and strong magnetic fields can be tuned to create a gapped 2D system with one dimensional channels along the edge. Interactions among these edge modes can lead to independent transport of charge and heat, even in opposite directions.
