Special Superconducting magnets for HiLumi LHC The luminosity upgrade of the Large Hadron Collider at CERN, which aims to increase the luminosity by a factor of more than five, includes as a relevant feature the replacement of many superconducting magnets, which are, to varying degrees, technically challenging and at the edge of technology. With 40 years of experience in the development of superconducting magnets, the Genoa and Milan Sections of INFN are involved in the development of some of these magnets that, while based on established NbTi technology, have required significant development activities by our laboratories. We are talking about the MBRD dipole, which separates and recombines the beams before and after the interaction points in CMS and ATLAS, and the higher-order correctors, a family of magnets that includes quadrupoles, sextupoles, octupoles, decapoles and dodecapoles. This seminar will explain all the activities carried out, from design to magnet series fabrication, to meet the performance required to be installed in the LHC.
