The HL-LHC Accelerator Upgrade Project magnets use conductors made of niobium-tin to generate a stronger magnetic field compared to predecessor technology. These world-record-setting magnets will have their debut in the HL-LHC: Its run will be the first time that U.S.-built niobium-tin magnets will be used in a particle accelerator for particle physics research.
