Plasma spectroscopy for magnetically confined fusion plasma
AIP Conference Proceedings, 2007An emission line of neutral helium λ667.8 nm (21P‐31D) is observed with a set of line of sights which covers an entire poloidal cross section of LHD, a heliotron‐type fusion experimental device. From the observed Zeeman splittings and the well‐known magnetic field structure in the plasma, the emission locations on the line of sight are precisely ...

Magnetic electrostatic plasma confinement
Plasma Physics and Controlled Fusion, 1994Electrostatic plasma confinement and magnetic electrostatic plasma confinement (MEPC) have been studied for four decades. The multiple potential well hypothesis, postulated to explain high neutron yields from Hirsch's colliding beam experiment (1968), has been supported by several pieces of evidence, but results were inconclusive. Magnetic shielding of

1990
Up to now, the principal efforts of fusion research have been devoted to better confinement of high temperature plasmas. In this chapter, we briefly outline these efforts. First in Sect. 9.1, we present the principle of thermonuclear fusion, with particular attention paid to the basic requirements imposed on a plasma used for the core of the ...

Magnetoreaction confinement of plasmas
Lettere Al Nuovo Cimento Series 2, 1985When energy is injected into a multicomponent magnetoplasma momentum balance may lead to the radial expulsion of one component and the simultaneous reaction confinement of the others.

Cyclotron Radiation from Magnetically Confined Plasmas
The Physics of Fluids, 1959The cyclotron emission from a hot, completely ionized, magnetically confined plasma has been estimated by computing the absorption of an incident plane wave. The harmonics of the fundamental cyclotron frequency, which are emitted perpendicular to the magnetic field direction, were summed over and also treated individually. Because of the Doppler effect

Plasma confinement in stellarator systems
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1981The stellarator is a plasma confinement system in which the magnetic field configuration is produced by currents in conductors outside the plasma. Plasma current is not necessarily required for confinement or for heating the plasma. Results from the CLEO and W VIIA experiments are presented to illustrate the progress in the understanding of containment

Theoretically Stable and Confined Plasma
The Physics of Fluids, 1962Certain distributions of plasma confined in a potential well are stable against a growth of space charge, as governed by the linearized Vlasov-Boltzmann equation with only Coulomb interactions between particles. lt is shown that these same distributions remain stable when magnetic as well as electrostatic forces between particles are admitted.

Computer Modelling of Magnetically Confined Plasmas
2009Magnetic plasma confinement research poses multifaceted requirements for computational modelling. The determination of plasma equilibria, the prediction of their global stability, the physics of plasma heating, the estimation of the energy losses out of the plasma and the interaction of the energetic plasma with the walls require all support by ...

Magnetic confinement of fusion plasmas
The Physics Teacher, 1981Starting with the Lorentz force law, the basic physics involved in magnetic confinement in thermonuclear reactors is reviewed. Among the topics covered are magnetic bottles, tokamaks, tandem mirrors, and energy balance considerations.(AIP)

Surface barrier confinement of plasmas
Lettere Al Nuovo Cimento Series 2, 1985We examine a new type of confinement system wherein a thin surface layer prevents plasma transport across a magnetic field.
