Tokamak Edge Plasma Turbulence Interaction with Magnetic X-Point in 3D Global Simulations

open access: yesFluids, 2019
Turbulence in the edge plasma of a tokamak is a key actor in the determination of the confinement properties. The divertor configuration seems to be beneficial for confinement, suggesting an effect on turbulence of the particular magnetic geometry ...

Chaotic motion of charged particles in toroidal magnetic configurations [PDF]

open access: yes, 2014
We study the motion of a charged particle in a tokamak magnetic field and discuss its chaotic nature. Contrary to most of recent studies, we do not make any assumption on any constant of the motion and solve numerically the cyclotron gyration using ...

Pulsar Magnetosphere: Variation Priciple, Singularities, Estimate of Power [PDF]

open access: yes, 2005
We formulate variation principle for force-free magnetosphere of an inclined pulsar: ${\cal E} +{\bf \Omega}\cdot {\bf M}$ ($\cal E$, ${\bf M}$ are electromagnetic energy and angular momentum, ${\bf \Omega}$ is the angular velocity of a star) is ...

Solitary magnetic perturbations at the ELM onset [PDF]

open access: yes, 2012
Edge localised modes (ELMs) allow maintaining sufficient purity of tokamak H-mode plasmas and thus enable stationary H-mode. On the other hand in a future device ELMs may cause divertor power flux densities far in excess of tolerable material limits. The

Dynamics of the Transition corona [PDF]

open access: yes, 2014
Magnetic reconnection between open and closed magnetic field in the corona is believed to play a crucial role in the corona/heliosphere coupling. At large scale, the exchange of open/closed connectivity is expected to occur in pseudo-streamer structures.

Observations of separatrix motion during the formation of a field-reversed configuration [PDF]

open access: yes, 1981
An axial array of B/sub z/ probes is used to monitor the formation and initial motion of the x-point of the separatrix in a field-reversed configuration. The x-point is observed to form near the outside edge of the main coil at approximately 3.0 ..mu..s after main field initiation and then move rapidly toward the center of the coil.

Modeling of plasma beta effects on the island divertor transport in the standard configuration of W7-X

open access: yesNuclear Fusion, 2023
The influence of plasma beta effects on the edge plasma transport in the Wendelstein 7-X standard configuration is studied systematically by using EMC3-EIRENE combined with a 3D equilibrium code named HINT. The magnetic topology changes induced by plasma

Chaos in Anisotropic Pre-Inflationary Universes [PDF]

open access: yes, 1997
We study the dynamics of anisotropic Bianchi type-IX models with matter and cosmological constant. The models can be thought as describing the role of anisotropy in the early stages of inflation.

On the force-free magnetosphere of aligned rotator [PDF]

open access: yes, 2005
We investigate in details properties of stationary force-free magnetosphere of aligned rotator assuming the last closed field line lying in equatorial plane at large distances from pulsar.
