Summary
This technical review documents the development of advanced superconducting magnets for CERN's High Luminosity LHC upgrade, scheduled for deployment by 2035–2040. The project requires construction of 150 magnets across six types, including 30 Nb₃Sn quadrupole triplets operating at 11.4 T—the first of their kind in a particle accelerator—and five types of Nb–Ti magnets manufactured through international in-kind contributions. The paper summarises design selections, technological challenges, and validation approaches as the project transitions from prototype testing to series production.
Key measures
Magnet specifications including operational peak field (11.4 T for Nb₃Sn quadrupole triplets), aperture size, magnet types and quantities, manufacturing locations and timelines
Outcomes reported
The paper reviews magnet requirements, design rationale, and technological challenges for the HL-LHC upgrade project, summarising validation steps taken during the transition from prototype qualification to series construction of approximately 150 magnets across six different types.
