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

Abstract

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.
