Abstract
The mathematical models and computation results for plasma confinement in magnetic traps called “Galatheyas” and for the evolution of the neutral current sheet in the vicinity of the magnetic zero line are compared. The computer simulations of plasma, magnetic field, and electric current configurations and their formation are based on solving MHD problems. Models of equilibrium configurations in the Galatheya–Belt trap and the current sheet use different dependences p(Ψ) of the plasma pressure on the magnetic flux function in the boundary problems with the Grad–Shafranov equation. Time-dependent models of the configuration formation in both setups differ by the electric current regime in the conductors producing the magnetic field.
