Abstract

The basic goal of magnetic confinement is to maintain plasma in an equilibrium state for an extended period using a magnetic field configuration. The plasma equilibrium configuration significantly affects the confinement efficiency and stability of the magnetic confinement device, and we anticipate that the equilibrium discharge of the Trimyx Galatea magnetic trap device will operate in an optimal configuration. The Grad–Shafranov equation, a mathematical model of two-dimensional magneto-fluid static equilibrium of the Trimyx Galatea magnetic trap, was established. Numerical calculations were performed under the conditions of a given magnetic field configuration and plasma pressure distribution and the evolution laws of the distinctive parameters of the equilibrium configuration were determined under different plasma confinement settings. The magnetic specific volume coupling model was further developed to demonstrate the mechanism of the influence of the magnetic trap magnetic field on the plasma confinement efficiency and properties.
