Description
Tokamak plasma operation and control requires precise knowledge and control of the plasma MHD force balance equilibrium. The MEQ software is a suite of magnetic equilibrium codes able to reconstruct the magnetic field from measurements on sub-millisecond timescales, predict plasma evolution, and compute required coil currents to achieve a desired plasma state and geometry. We present different strategies for solving the underlying non-linear system posed by the Free-Boundary Grad-Shafranov equation and investigate stability and convergence of Newton solvers for various formulations of the residual. Finally, we discuss future directions, including the integration of machine learning for real-time simulation and control.
