Transition to deployment phase approaching: update on project status
Impressive progress has been made across the entire collaboration, with production progress vital as we continue to progress towards deployment in the LHC tunnel. The upcoming Collaboration Meeting will be an exciting time to meet just after the start of deinstallation of the machine, to reflect on what we have achieved so far and what…

Machine protection: DQHDS series production advances as IT String tests validate HiLumi LHC protection systems
Delivery of Quench Heater Discharge Power Supply (DQHDS) units from KEK is steady, with adaptations being made in response to increased fuel costs. Testing both in Japan and at CERN, and system-level testing in the IT String offer confidence in the technology’s readiness, and for the consolidation of the individually-powered dipole and quadrupole (IPD and…

IT String: from leak non-conformity observation to first commissioning phase
The IT String is in its operational phase, with many lessons already learnt during the tests so far. The path to this phase – including detection and resolution of a non-conformity, and cooldown – has provided valuable insights and fostered strong collaboration across teams. Leak non-conformity: detection to resolution Following the successful completion of most…

From Work Package deliverables to the fully integrated HL-LHC magnet circuits
By nature, HL-LHC magnet circuits span many different technical domains and teams. Two dedicated international reviews – in 2016 and 2019 – and three internal CERN reviews – in 2017, 2020 and 2023 – have helped shape the HL-LHC magnet circuits, the associated instrumentation and the constituting systems being prepared at CERN and throughout the…

Mid-term planning for testing of components in SM18
The SM18 test facility continues to play a central role in validating critical components for the HL-LHC Project. Currently all upgrades of the various test stations have been completed, including a second cold box providing helium for the IT String, a large update campaign for magnet test benches, new instrumentation hardware with quench antenna and…

IT String – Completion of installation of major components and start of interconnection works
The HL-LHC IT String installation is entering its final phase in the SM18 building at CERN. All major components are now in place, following a series of installation and validation activities executed by the end of 2024 and beginning of 2025. These tasks have been carried out on schedule, within scope and following extensive preparations…

HL-LHC IT String advances
As highlighted in the latest report on the HL-LHC IT String, the installation and operation of this test stand marks a very significant milestone for the High Luminosity LHC (HL-LHC) project. Most of the state-of-the-art technologies developed within the scope of the project will prove that they can effectively work in harmony, simulating diverse operational…

The IT String making big leaps towards its operation
The HL-LHC IT String is a major, intermediate milestone for the HL-LHC project ahead of the installation of the first cold powering systems in the LHC tunnel during LS3. The IT String will enable testing of the collective behavior of many new key hardware systems designed for the new era of the High Luminosity LHC.…

Decision to delay the IT String test by one year and to limit the IT String test to one year operation
The HL-LHC magnets and cold powering systems are planned to be tested individually on dedicated test benches in the SM18 test facility at CERN or at the collaborators test facility (e.g. at Fermilab in the USA). The HL-LHC IT STRING will reproduce on the surface the configuration of the left side of Point 5 with…
