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).

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 ...

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.

Access to stable, high pressure tokamak pedestals using local electron cyclotron current drive
Nuclear Fusion, 2023 Experiments on the DIII-D tokamak demonstrate that edge localized mode (ELM) stability can be manipulated using localized electron cyclotron current drive (ECCD) in conjunction with resonant magnetic perturbations (RMPs).

TEM analysis of recrystallized double forged tungsten after exposure in JUDITH 1 and JUDITH 2
Nuclear Materials and Energy, 2016 Five samples of recrystallized pure tungsten were exposed to transient heat loads using the electron beam of the JUDITH 1 and JUDITH 2 installations of Forschungszentrum Jülich.

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.

Wall conditioning and ELM mitigation with boron nitride powder injection in KSTAR
Nuclear Materials and Energy, 2021 Results from KSTAR powder injection experiments, in which tens of milligrams of boron nitride (BN) were dropped into low-power H-mode plasmas, show an improvement in wall conditions in subsequent discharges and, in some cases, a reduction or elimination ...

Edge localized mode control with an edge resonant magnetic perturbation [PDF]
Physics of Plasmas, 2005 A low amplitude (δbr∕BT=1 part in 5000) edge resonant magnetic field perturbation with toroidal mode number n=3 and poloidal mode numbers between 8 and 15 has been used to suppress most large type I edge localized modes (ELMs) without degrading core plasma confinement. ELMs have been suppressed for periods of up to 8.6 energy confinement times when the
