Real-time reconstruction of the magnetic flux in ftu using multipolar current moments

An important goal of magnetic field study in tokamak machines is to determine and reconstruct the magnetic iso-flux surface characterizing the plasma boundary condition and the full mapping of the magnetic surfaces inside that iso-flux surface. This task can be accomplished by using the multi-polar moment method which results from the homogenous solution of the Grad-Shafranov equation. The real-time reconstruction of magnetic field map is important to evaluate some quantities that can be use to control the plasma. This paper addresses' the real-time implementation of that task.
