Hardware Commissioning of the HL-LHC Inner Triplet String Facility at CERN: Individual System and Short Circuit Tests
/ Yammine, Samer (CERN) ; Antoine, Alain (CERN) ; Onufrena, Aleksandra (CERN) ; Perin, Antonio (CERN) ; Panev, Bozhidar Ivanov (CERN) ; Bozzini, Davide (CERN) ; Coulot, Emilien (CERN) ; Thiesen, Hugues (CERN) ; Zerlauth, Markus (CERN) ; Bajko, Marta (CERN) et al.
The goal of the High Luminosity-Large Hadron Collider (HL-LHC) Inner Triplet (IT) String test, is to validate the assembly and connection procedures and tools required for its construction, to assess the collective behavior of the superconducting magnet chain in conditions as close as possible to those of their operation in the HL-LHC and to provide a training opportunity for the equipment teams for their work in the LHC tunnel. The IT String includes the systems required for operation at nominal conditions, such as the cryogenics, powering and quench protection systems. [...]

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. [...]

A Modernized Architecture for the Post Mortem System at CERN
/ Barth, Jonas (CERN) ; Bogyai, Filip (CERN) ; Garnier, Jean-Christophe (CERN) ; Majewski, Marcin (CERN) ; Martins Ribeiro, Tiago (CERN) ; Mnich, Aleksandra (CERN) ; Pocwierz, Maciej (CERN) ; Selvek, Robert (CERN) ; Simpson, Robert (CERN) ; Stanisz, Anita (CERN) et al.
The control system of the accelerators at CERN stores and analyzes more than 200 million dumps of high resolution data recordings every year in the Post Mortem (PM) system. A continuous increase in the complexity of the Large Hadron Collider’s (LHC) systems and the desire to collect more accurate data requires continuous improvement of the PM system. [...]

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.

Operational Scenario of First High Luminosity LHC Run
/ Tomás García, Rogelio (CERN) ; Arduini, Gianluigi (CERN) ; Baudrenghien, Philippe (CERN) ; Bruce, Roderik (CERN) ; Brüning, Oliver (CERN) ; Buffat, Xavier (CERN) ; Calaga, Rama (CERN) ; Cerutti, Francesco (CERN) ; De Maria, Riccardo (CERN) ; Dilly, Joschua (CERN) et al.
A new scenario for the first operational run of the HL-LHC era (Run 4) has been recently developed to accommodate a period of performance ramp-up to achieve an annual integrated luminosity close to the nominal HL-LHC design. The operational scenario in terms of beam parameters and machine settings, as well as the different phases, are described here along with the impact of potential delays on key hardware components..
