Upgrading the LHC beyond its design performance is a long term program that started during the LHC construction, with some fundamental R&D programs. The upgrade program is based on a vigorous superconductor and magnet R&D, aimed at increasing the field in accelerator magnets from 8 T to 12 T for the luminosity upgrade, with the scope of increasing the collider luminosity by a factor 5 to 10 from 2022. The upgrade program might continue with the LHC energy upgrade, which would require magnets producing field in the range of 16-20 T. The results obtained so far and the future challenges are discussed together with the possible plan to reach the goals.

The High Luminosity LHC interaction region magnets towards series production

“…One year before the Higgs boson discovery, the High Luminosity LHC (HL-LHC) design study was launched [11], aiming at a substantial upgrade of the LHC to increase the statistics of the collision data by a factor of ten. This design study was the last stage of a 10 years long period of investigations on the possibilities of improving the LHC performances, started in 2000 [12][13][14].…”
