Description
The "SupraFusion" program is a French initiative dedicated to advancing High-Temperature Superconductor (HTS) technology. HTS materials enable ultra-high magnetic fields (>20 T) at low temperatures (4 K - 20 K), potentially revolutionizing fields such as fusion energy, wind power, and medical imaging. The program's primary goal is to establish France as a leader in HTS research and innovation, leveraging nuclear fusion as a key driver. Divided into five research projects spanning the entire lifecycle of HTS technology, from material development to final applications like fusion reactors, SupraFusion seeks to drive progress in this field. One crucial project focuses on designing, fabricating, and testing a demonstrator magnet. This document outlines the initial approach used to define the performance specifications for the SupraFusion demonstrator magnet. It describes the overall concept, including an insulated conductor housed within a radial-plate-like mechanical structure and potential cooling methods. Based on quench detection/protection assumptions, sizing parameters are selected for the demonstrator. Subsequently, 3D electromechanical simulations are conducted using these parameters and finely analyzed taking into account stress orientation along the conductor and Tresca stress in the massive parts. The mechanical structure is then refined through a parametric investigation. The results are analyzed and discussed to provide a preliminary conceptual design for the SupraFusion demonstrator magnet.
