Abstract: | The mathematical apparatus of plasmastatics, which includes the MHD equilibrium equation and steady-state Maxwell equations,
is reduced, in two-dimensional problems arising due to symmetry, to a single scalar second-order elliptic equation with a
nonlinear right-hand side known as the Grad-Shafranov equation. In this paper, we numerically solve a series of boundary value
problems for this equation that model equilibrium plasma configurations in the magnetic field of the belt-like galathea trap
in a cylinder with two plasma embedded conductors. The mathematical model is outlined, the results of calculations of the
magnetic field and plasma pressure in the cylinder depending on the parameters of the problem are presented, and the main
integral characteristics of the trap are calculated. The existence and uniqueness of the solution is discussed; the limiting
values of the maximal pressure at which there exists a solution of the equilibrium problem are found. |
