10 Shares The High-Luminosity Large Hadron Collider (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 project at CERN. 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.
