The HL-LHC project, recently approved at CERN, aims at gathering 3000 fb-1 in the decade after the long shutdown 3. It relies on several advanced technologies, some of them being implemented for the first time in a particle accelerator. A relevant part of the project is the replacement of nearly 1 km of the lattice around Atlas and CMS with larger aperture magnets to allow to halve the beam size in the interaction points. In this talk we will review the main milestones of the magnets of HL-LHC, from the beginning of the design study in November 2011 to the present phase of short model and prototype construction.
Today, most of the design and parameters have been fixed. Eleven different types of magnets will be needed, relying on technologies ranging from Nb3Sn to NbTi, and to nested and superferric correctors. The rational behind the choices for the magnets will be outlined, in terms of margin, technology, electromagnetic and mechanical design. We will discuss the main challenges of this project, giving an outlook of the activities in the next years.
