Magnet Technology advances for sustainable research infrastructures through High Temperature Superconductor (HTS4SRI)

The HTS4SRI project pioneers a holistic methodology for applying High-Temperature Superconducting (HTS) technology to the sustainable design, manufacturing, and operation of magnets in large European research infrastructures. Its central goal is to establisha systematic framework where conductor development, cryogenics, cryogenic power supplies, and assembly processes are jointly optimized under sustainability criteria such as life-cycle assessment, recyclability, and energy efficiency. This integrated approach ensures that environmental objectives are embedded across the full magnet lifecycle—from conception to operation. As proof of feasibility, HTS4SRI will design and qualify large-aperture quadrupole coils and two complementary pilot magnets—a dipole for continuous beam operation and a compact combined-function magnet for broad accelerator applications. Together with the coils, these demonstrators will validate the methodology in diverse operational environments, including radiation exposure, and demonstrate the potential for more than 50% reduction in magnet-related electricity consumption compared with resistive technologies. The work plan, structured into six interconnected work packages, will deliver: • A sustainability-driven design methodology integrating conductor development, cryogenics, cryogenic powering, and assembly under eco-design principles • Eco-design guidelines and replicability standards for sustainable HTS coils and components • An open-access database on HTS conductor performance and environmental impact • Large-aperture quadrupole coils and pilot demonstrators (dipole and compact combined-function magnet) validating the multi- aspect methodology A cornerstone of HTS4SRI is its strong focus on communication and dissemination. The project will implement structured programs—webinars, workshops, and mini-schools—to equip technicians, engineers and scientists with the skills required for sustainable magnet design and manufacturing.
