The High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN is a major upgrade project of the LHC accelerator, which will allow increasing the peak luminosity by at least a factor of five beyond LHC’s design value. This upgrade will include the replacement of the final focusing superconducting magnets and the implementation of superconducting radiofrequency crab cavities in the long straight sections of the interaction points 1 and 5 of LHC.

/ Sisti, M (CERN) ; Claudet, S (CERN) ; Metselaar, J (CERN) ; Lees, A (CERN) ; Merli, F (CERN) ; Perin, A (CERN) ; Gahier, V (CERN)
The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) will require the replacement of the final focusing superconducting magnets, the implementation of new superconducting links to power the magnets and the implementation of new Superconducting Radio-Frequency (SRF) crab cavities, totalling a length of about 150 m on both sides of the collision points of the ATLAS (P1) and of the CMS (P5) experiments in the LHC accelerator. To cool the new and reconfigured cryogenic devices, a new Cryogenic Distribution System will replace the existing LHC cryogenic distribution line on each side of the experiments. [...]

For the High Luminosity LHC (HL-LHC) project, the final focusing Inner Triplet (IT) superconducting magnets of the LHC will be replaced by a new 60 m-long set of higher performance Nb$_{3}$Sn magnets that will operate at 1.9 K in pressurised He II. A test facility, the HL-LHC IT String, is currently being built to validate the collective behaviour of these new magnets and of the related systems. [...]

Detailed study of the cryogenic jumper connections between the cryogenic distribution line and the superconducting magnets of the High Luminosity LHC upgrade at CERN
/ Merli, F (CERN) ; Claudet, S (CERN) ; Ramos, D (CERN) ; Lees, A (CERN) ; Perin, A (CERN) ; Prin, H (CERN) ; Sisti, M (CERN)
The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) project will require a new cryogenic system to cool the new superconducting components in the final focusing regions for the ATLAS and the CMS experiments. New superconducting magnets operating in pressurized HeII at 1.9 K will replace the existing ones and each magnet will generate heat loads of several hundred watts. [...]

The HL-LHC IT String, a test facility for the major components of the HL-LHC Inner Triplet, is currently in its construction and commissioning phases in a surface building at CERN. The primary motivation of the HL-LHC IT String is to study and validate the collective behaviour of its different subsystems which include mainly: the inner triplet superconducting magnets and their correctors, a novel superconducting link, the cryogenics infrastructure for the cooling and quench recovery, the powering and quench protection systems, and the remote alignment system.

The paper focuses on the qualification process employed to ensure the precision and reliability of radiation tolerant pressure sensors, originally developed to operate within the temperature range of -40°C to +125°C, in superfluid helium for CERN cryogenic installations. The initial stage of the qualification protocols took place at the CERN CryoLab facility. [...]

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. [...]

The discovery of a Higgs boson at CERN in 2012 was the start of a major program working to measure this particle’s properties with the highest possible precision for testing the validity of the Standard Model and to search for further new physics at the energy frontier. The LHC is in a unique position to pursue this program. [...]
