A demonstrator high-current superconducting cable developed at CERN, using high-temperature superconducting (HTS) tapes, and inspired by developments for advanced nuclear fusion reactors. The cable consists of a hollow copper profile hosting HTS tapes in twisted grooves. When cooled to 20 K, a cable of this class can carry currents up to 60 kA in fields up to 20 T. (Image: CERN)

On 10 September 2025, CERN and Fusion for Energy (F4E) signed a major framework collaboration agreement to advance scientific research and technological development in areas of common interest. F4E is the European Union organisation managing Europe’s contribution to ITER – the world’s largest scientific experiment on the path to fusion energy.
