In the past, both workshops proved to be a lively platform to gather experts from all over the world to discuss progress and challenges within the field. The strongly connected topics of both workshops led to the decision to join efforts and organize a combined workshop. The MEM workshop is an opportunity to present recent progress and development of the mechanical and electromagnetic properties of LTS and HTS composite superconductors. The HTS4Fusion Conductor Workshop focuses on High-Temperature Superconductor (HTS) application for fusion research, e.g. HTS conductors for fusion magnets.
