Research On Plasma Confinement In Magnetic-coupling Field In Galatea

Plasma confinement by magnetic field is a major problem of controlledthermonuclear fusion. The Galatea we research is proposed by A.I.Morozov are ofspecial interest, in which the current-carrying conductors are merged in the plasmavolume. As a result, it is possible to vary the geometry of the magnetic field in thetraps to a greater degree and, thus, expect higher confinement parameters. TheGalatea has not a related research paper domestic, we start with plasma confinementmagnetic configuration, then study plasma confinement by buildingMHD(magnetohydrodynamics) equilibrium model and discuss the spread ofparticles. An optimization program for the device and the plasma parametermeasurement system are also proposed. It is important to introduce and improve theGalatea device, which carries out new research direction for plasma confinementdomestic.Firstly, the structure of the Galatea are introduced, we analysis the principle ofoperation of the various components and discuss the basic parameters of plasmaresearch and theoretical methods;Secondly, the magnetic configuration of plasma confinement is discussed, thenwe analyze plasma confinement in the magnetic mirror field, as well as take asimulation analysis of the magnetic traps configuration without plasma-filled. Laterwe study the single-particle confinement in a magnetic trap. We build the MHDplasma model to analysis the equilibrium of confinement plasma with the resistanceand heat diffusion in plasma.Then, we discuss plasma motion parallel and perpendicular to the magneticfield, consider the form of plasma diffusion. To improve the confinement parameterswe adding a vertical magnetic and increasing the barrier magnetic field;Finally, according to the previous theoretical research results, Combined withthe magnetic fluid model distributions of plasma, we propose the measurements ofplasma parameters and establish measurement system.
