Fusion plasmas with reactorlike temperatures have been confined in magnetic-field configurations of the tokamak type. The measured rate of heat leakage from these plasmas is sufficiently small to be compatible with the requirements of a full-sized fusion power reactor.

On a Magnetically Confined Plasma with Infinite Charge
SIAM Journal on Mathematical Analysis, 2014We consider a one-species plasma moving in an infinite cylinder, in which it is confined by means of a magnetic field diverging on the walls of the cylinder. It is assumed that initially the particles have bounded velocities and are distributed according to a density which is bounded, without any decreasing at infinity.

Magnetic Domain Confinement by Anisotropy Modulation
Physical Review Letters, 2002The spin configuration in a magnet is in general a "natural" consequence of both the intrinsic properties of the material and the sample dimensions. We demonstrate that this limitation can be overcome in a homogeneous ferromagnetic film by engineering an anisotropy contrast. Substrates with laterally modulated single-crystal and polycrystalline surface

We discuss advantages of surface confinement such as plasma stability, direct injection of ion beams, electrostatic confinement, negligible synchrotron loss, and ''geometric mirror.'' Preliminary experimental results are presented. (AIP)

Our modern society requires environmentally friendly solutions for energy production. Energy can be released not only from the fission of heavy nuclei but also from the fusion of light nuclei. Nuclear fusion is an important option for a clean and safe solution for our long-term energy needs.

A review is given of the present state of research into the physics of quasistationary confinement of hightemperature plasmas in magnetic fields. Both closed (toroidal) and open magnetic traps are considered. A major part of the review is devoted to the physics of plasma confinement in tokamaks.

Annals of the New York Academy of Sciences, 1975
The theoretical plasma confinement times for an electromagnetic trap, which is an electrostatically plugged magnetic cusp device, are calculated. The plasma may be produced by electron beam injection or by other methods. Electron losses along field lines are inhibited by negative electrodes (cathodes) placed at the cusp openings.

Magnetically Confined Plasma with a Maxwellian Core
Physical Review, 1962While a magnetically confined plasma cannot have a Maxwellian velocity distribution at each point, it is shown that a high beta Maxwellian plasma containing no magnetic fields can exist when separated by a non-Maxwellian boundary layer from the region of no plasma and homogeneous confining magnetic field.

Nuclear magnetic resonance of confined MBBA
Magnetic Resonance Imaging, 1996Confinement of liquid crystals in small pores changes their thermodynamic, structural, and dynamical properties. In this study we are concerned with solid, liquid crystalline, and isotropic liquid phase behaviour of the nematogenic compound MBBA confined in small pores of variable diameters.
