The rapid development of the fusion industry has created an urgent demand for high-performance superconducting materials capable of operating in extremely high magnetic fields. Most advanced compact fusion reactor concepts rely on powerful magnet systems generating magnetic fields over 20 T to confine high-temperature plasma. Such magnetic systems are only possible with the second generation of high-temperature superconducting tapes (2G HTS), which can sustain high engineering current densities (Je) in high-field environments.
Faraday Factory Japan (FFJ) has been the pioneer in the industrial-scale production of 2G HTS tapes for fusion applications since 2019, when we introduced our first fusion-grade 2G HTS tape, Hermes, featuring Je of 600–1000 A/mm² at 20 K and 20 T.
Over the past five years, FFJ has become the world leader in the manufacturing of 2G HTS, delivered more than 8000 km of Hermes tape to leading fusion start-ups worldwide and significantly scaling up our production capacity. Hermes tape has demonstrated exceptional reproducibility and long-term stability of key parameters. Magnet prototypes built with Hermes tapes have successfully passed qualification tests in multiple fusion reactor concepts, including tokamak developed by Commonwealth Fusion Systems (CFS), stellarator developed by Thea Energy and Proxima Fusion, and levitated dipole developed by OpenStar Technologies.
Based on this unique practical experience and an extensive R&D program, FFJ has developed an advanced pulsed laser deposition (PLD) process for the industrial-scale production of high-Je tapes. In this presentation, we introduce our new product: the Mirai tape, with Je up to 1500 A/mm² at 20 K and 20 T — a performance level unmatched on the current superconducting market. Mirai tape opens new opportunities for designing and building high-field magnets for demanding applications generating fields up to 40 T and beyond.
