Magnetic islands in a magnetized plasma with electron flow
Physical Review E, 1998A system of two coupled nonlinear equations describing magnetic electron modes in a magnetized inhomogeneous plasma with a spatially dependent electron flow is derived. For a homogeneous basic state electron concentration, the two equations can be decoupled, and a nonlinear solution for the magnetic field in the form of a traveling stationary vortex ...

Reconnection of coalescing magnetic islands
Physics of Plasmas, 1999The dynamics of magnetic reconnection in the framework of two-dimensional incompressible magnetohydrodynamics is studied numerically. The case of a doubly periodic array of magnetic islands where coalescence of neighboring islands occurs due to self-consistent magnetic forces is investigated.

Explosive Coalescence of Magnetic Islands
IEEE Transactions on Plasma Science, 1986An explosive reconnection process associated with nonlinear evolution of the coalescence instability is found through studies of particle and magnetohydrodynamic (MHD) simulations. The explosive coalescence is a self-similar process of magnetic collapse, in which the magnetic and electrostatic energies and temperatures explode toward the explosion time

Evolution of magnetic islands in tokamaks
Nuclear Fusion, 1980The evolution of magnetic islands is studied by a variational method on the assumption that it consists of a sequence of equilibria. The characteristic time of the evolution is then a resistive time. The sequence may, however, reach a configuration where the angle of the flux lines at the X-point vanishes. This behaviour is plausible in the case of q =

Self-excitation of magnetic islands
Nuclear Fusion, 1994A mechanism of island self-excitation is discussed in detail, by studying the dynamical interaction, in a tokamak plasma, of a suitably defined ensemble of ions with the electrostatic field of densely packed island chains, assuming that the ion Larmor radius is larger than the island width.

The nonlinear saturation of a magnetic island
Plasma Physics and Controlled Fusion, 1989The author obtains a nonlinear amplitude equation in slab geometry which describes the growth and saturation of a magnetic island. This is done by extending the earlier work of P. Rutherford (1974) to include nonlinear terms. The width of the saturated island is shown to be determined by the current profile, for a nonsymmetric profile.

Magnetic charts of the island of Sardinia
Terrestrial Magnetism and Atmospheric Electricity, 1909Several years ago I had the honor of presenting to the readers of Terrestrial Magnetism the magnetic chart of Sicily. I now venture to believe that some magnetic charts of the second in importance among the large Italian islands, Sardinia, would not be out of place in this Journal, especially as Sardinia reveals even more pronounced and characteristic ...
