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…

Beam-gas curtain production and testing on track, and SPS tests of electro-optical BPM ongoing
The novel beam-gas curtain prototype, installed in the LHC, is providing valuable insights on beam profile measurements in the High-Luminosity era for both proton and ion beams, and production of the second of the series is foreseen before LS3. The Beam-Gas Curtain (BGC) collaboration is part of the HL-UK agreement producing a novel instrument for measuring transverse beam…

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…

Long Shutdown 3 incoming: installations already heating up in the HiLumi LHC galleries
Since the summer of 2025 installations in the new High-Luminosity (HiLumi) LHC surface buildings and underground galleries at Points 1 and 5, and preparations for de-installation and installation works in Long Shutdown 3 (LS3), have been progressing at a high pace. On the surface, the installation of the cooling and ventilation systems in the SU…

Optimising HL-LHC activities for the LS3 schedule
The LS3 LHC schedule, including the HL-LHC activities, was presented at the LS3 Readiness Review on 11-13thSeptember 2024. Following this review, a significant update was announced: LS3 will commence in the LHC on 29thJune 2026. By then, the critical path duration for the LS3 LHC in-work schedule was 51.5 months. Thanks to an intense optimisation…

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…

Cold Powering System: confidence and validation for future installations, and series production progress
The HL-LHC Cold Powering Systems transfer the current from the power converters, located in the new underground galleries, to the superconducting magnets of the HL-LHC Inner Triplets and Matching Sections, in the LHC tunnel, on either side of Point 1 and Point 5. Eight systems plus two spares of two different types, X for the…

HL-LHC magnets: progress across the collaborations and at CERN
Since the last newsletter in June 2024, the interaction region (IR) magnets for the HL-LHC have reached several key milestones. One of the most significant achievements was the delivery of all cryo-assemblies to the IT String, including the DCM connection module, marking a major step forward in the integration process. With Work Package 3 now…

Update of project status
The HL-LHC project has continued to make impressive progress since the annual meeting in Genoa at the end of 2024. In particular I would like to highlight here the celebrations for the first Beam Screen being completed at CERN, the successful repair of the prototype RFD Crab Cavity cryo-module and its on-time installation in the…

Long Shutdown 3 schedule and readiness review
The HL-LHC Project will culminate with the accomplishment of a very demanding installation phase during the Long Shutdown 3 (LS3). To assess the project’s readiness, a tracking process on the expected availability of equipment has been implemented. The careful follow-up of this installation schedule float plays an important role in the strategical decision-making process. It…
