Development of Turbulent Magnetic Reconnection in a Magnetic Island
The Astrophysical Journal, 2017 Abstract In this paper, with two-dimensional particle-in-cell simulations, we report that the electron Kelvin–Helmholtz instability is unstable in the current layer associated with a large-scale magnetic island, which is formed in multiple X-line guide field reconnections.

Non-disruptive error field identification based on magnetic island healing
Nuclear Fusion, 2022 A technique to identify intrinsic error fields (EFs) in tokamaks with minimized risk of disruption is demonstrated on the DIII-D tokamak. The method extends the conventional driven magnetic island ‘compass scan’ approach by modifying asynchronous control

The Innovation, 2022 How animals sense the geomagnetic field remains a mystery today. A remarkable diversity has been revealed in animal magnetoreception and several sophisticated models have been put forward in the past few decades, but none have been commonly accepted yet.

Anisotropic E × B shearing rate in a magnetic island
Physics of Plasmas, 2021 We derive the E × B shearing rate associated with vortex flow inside a macroscopic magnetic island (MI) in axisymmetric toroidal geometry. Due to the elongation of the MI and incompressibility of the E × B flow, the shearing rate near X-points is much ...

Plasma Physics and Controlled Fusion, 2021 A new drift kinetic theory for the plasma response to the neoclassical tearing mode (NTM) magnetic perturbation is presented. Small magnetic islands of width, w≪a (a is the tokamak minor radius) are assumed, retaining the limit w ∼ ρ bi (ρ bi is the ion ...

Translational Oncology, 2021 Studies have shown that 9.4 Tesla (9.4 T) high-field magnetic resonance imaging (MRI) has obvious advantages in improving image resolution and capacity, but their safety issues need to be further validated before their clinical approval.

Coalescence of Magnetic Islands [PDF]
Physical Review Letters, 1980 The process of coalescence of magnetic islands is investigated. For intermediate values of the resistivity eta, the reconnection rate M/sub s/ is independent of eta, although the reconnection process is basically different from a Petschek-type model. For very small values of eta the dynamics of the coalescence process is more complex with reconnection ...

Interplay among turbulence, flow and impurities for sustaining magnetic island
Nuclear Fusion, 2023 As ubiquitous structures in magnetized fusion plasmas, magnetic islands (MIs) would short-circuit adjacent magnetic flux surfaces and result in a reduced pressure gradient and fluctuations inside the island; it is widely accepted that due to the ...

Magnetic island merger as a mechanism for inverse magnetic energy transfer [PDF]
Physical Review Research, 2018 Magnetic energy transfer from small to large scales due to successive magnetic island coalescence is investigated. A solvable analytical model is introduced and shown to correctly capture the evolution of the main quantities of interest, as borne out by ...
