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…

Collaboration status in advance of Long Shutdown 3
As Long Shutdown 3 approaches, delivery schedules from the collaborations are more important than ever. A collaborative effort has seen good progress across the project worldwide, including from more-recent agreements with Pakistan and Brazil. International collaborations remain a central pillar of the High-Luminosity LHC (HiLumi LHC) project. Production activities are progressing well across all existing…

HiLumi LHC magnet programme transitioning from fabrication to integration
The High-Luminosity (HiLumi) LHC magnet programme continues to advance steadily across all collaborations, with major milestones reached in production, testing, and system integration. A significant highlight of the past 6 months is the cooldown of the Inner Triplet (IT) String, now at 1.9 K, with the first magnets already powered, marking an important step towards…

Crab cavity and RF developments across collaborations
Strides are being taken for the RFD and DQW crab cavities and cryomodules, with challenges being tackled and overcome across the collaborations, and more deliveries to CERN imminent. Important progress has also been made for the high-power RF components. RF Dipole Cryomodule for SPS Tests (CERN) The Radio Frequency Dipole (RFD) cryomodule in the SPS…

Cold Powering System transitions into preparation stages for installation following completion of collaboration deliverables
Following the steady progress of productions of the Cold Powering Systems, including the completion of deliverables from SOTON and Uppsala University, preparations are well underway for installation in the underground. Activities for the powering of the HiLumi magnets (Work Package 6A) in 2026 are focused on the assembly and testing of the series Cold Powering…

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…

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…

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…

LHC High-Intensity Tests paving the way for HiLumi LHC
During the two days dedicated to LHC high-intensity tests, the accelerator successfully operated with an unprecedented number of high-intensity bunches and provided encouraging results and valuable lessons ahead of the main high-intensity test campaign planned in late-June. Preparatory tests for the LHC high-intensity (HI) period, carried out on 4th to 6th May 2026 marked an important milestone…
