Application of the topological sensitivity method to the reconstruction of plasma equilibrium domain in a tokamak

Abstract

Abstract The topological sensitivity method is an optimization technique used in different inverse problem solutions. In this work, we adapt this method to the identification of plasma domain in a Tokamak. An asymptotic expansion of a considered shape function is established and used to solve this inverse problem. Finally, a numerical algorithm is developed and tested in different configurations.
