At its restart after a major shutdown in 2029, the LHC will see its interaction regions upgraded by the installation of the HL-LHC equipment, with new Nb3Sn triplets and cold powering system, crab-cavities for crossing angle compensation and luminosity levelling, an upgraded collimation system, and fully remote alignment for the final focusing region. In the following operational runs, the LHC will aim at a tenfold increase of the integrated luminosity compared to the original design. [...]

LHC Triplet Task Force Report
/ Arduini, Gianluigi (CERN) ; Bradu, Benjamin (CERN) ; Brodzinski, Krzysztof (CERN) ; Bruce, Roderik (CERN) ; Cerutti, Francesco (CERN) ; Ciccotelli, Alessia (University of Manchester (GB)) ; Deferne, Guy (CERN) ; Fartoukh, Stephane (CERN) ; Fessia, Paolo (CERN) ; Garion, Cedric (CERN) et al.
The excellent performance of the Large Hadron Collider (LHC) and the extension of Run 3 by one year have led to a significant increase of the expected integrated luminosity by the end of its operation and before the start of the High Luminosity LHC (HL-LHC), exceeding the design LHC integrated luminosity of 300 fb−1 for which the final focus region has been designed.

The HL-LHC Project Gets Ready for Its Deployment
/ Zerlauth, Markus (CERN) ; Brüning, Oliver (CERN) ; Di Girolamo, Beniamino (CERN) ; Fessia, Paolo (CERN) ; Gaignant, Christelle (CERN) ; Garcia Gavela, Hector (CERN) ; Maclean, Ewen (CERN) ; Modena, Michele (CERN) ; Otto, Thomas (CERN) ; Tavian, Laurent (CERN) et al.
Following the successful completion of the second long shutdown (LS2), the Large Hadron Collider (LHC) is preparing for its final operational run before the majority of the High Luminosity Upgrade (HL-LHC) will be installed during the third Long Shutdown starting in 2026. The HL-LHC upgrade will enable a further tenfold increase in integrated luminosity delivered to the ATLAS and CMS experiments, starting by an upgrade of the machine protection, collimation and shielding systems in LS2, and followed by the deployment of novel key technologies, including Nb₃Sn based insertion region magnets, cold powering by MgB₂ superconducting links and integration of Nb crab-cavities to compensate the effects of a larger crossing angle.

Chapter 15: Integration, (de-)installation and alignment
/ Fessia, Paolo (CERN) ; Mainaud Durand, Helene (CERN)
The HL-LHC will require modifying the machine and infrastructure installations of the LHC in several points along the Accelerator Ring, in particular: P1, P2, P4, P5, P6, P7 and P8.
Part of the modifications and improvement in P2, P4, P7 and P8 shall be completed during Long Shutdown 2 (LS2) and be operational for LHC Run 3, while the largest part of the interventions will take place in Long Shutdown 3 (LS3) and they will affect primarily P1, P4, P5, P6 and P7. The activities required point by point will be therefore listed and analysed here below..

This study explores the benefits of extending the monitoring and remote alignment concept, proposed in the HL-LHC baseline, to additional components of the matching sections of the HL-LHC. The objective of this study was to evaluate the benefits in terms of equipment performance and new opportunities for system simplification. [...]

The National Institute for Nuclear Physics (INFN) is developing at the Laboratory of Accelerators and Applied Superconductivity (LASA) laboratory (Milano, Italy) the prototypes of five corrector magnets, from skew quadrupole to dodecapole, which will equip the high-luminosity interaction regions of the High Luminosity Large Hadron Collider (HL-LHC). These magnets are based on a superferric design, which allows a relatively simple, compact, and easy to construct magnet. [...]
