Simulations of Eddy currents in the Seville spherical tokamak

Abstract

Achieving controlled nuclear fusion on Earth could be a decisive aspect on the climate change ght. It is also an exciting eld because of its scienti c and technological challenges. The Plasma Science and Fusion Technology group of the University of Seville is planning to build a magnetic fusion device, a spherical tokamak for research in di erent aspects on controlled nuclear fusion. This bachelor thesis is the rst numerical study on the vessel and coils con guration of the future Seville Spherical Tokamak. It analyzes four di erent con gurations taking into accout both plasma equilibria and dynamical aspects plasma discharge. The fundamentals of toroidal magnetic fusion devices such as spherical tokamaks are explained. An study study of four di erent con gurations for the Seville spherical tokamak is carried out using the FIESTA code. The main parameters of the four con gurations are compared, providing the best shape of the spherical tokamak, as well as valuable information about the coilset con guration of the device. i
