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…

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…

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…

The challenges of magnet sorting for the HL-LHC
Magnet sorting is a challenging process that aims at improving the performance of a particle accelerator by the clever choice of the position of the magnets to induce a natural compensation of the field errors that are inevitable in modern superconducting magnets. These studies are intrinsically multi-faceted and an appropriate figure of merit should be…

Status of SM18 test benches for SC magnets and SC-link, and test plan for 2024
Test bench requirements for the HL-LHC In the last years, the horizontal test benches have been modified to accommodate the HL-LHC magnet and SC-link test program. The number of HL-LHC magnet cryoassemblies to be validated (24 magnets + 8 SC-links + spares) is much lower than for the LHC, but there are more variations in…

Progress of HL-LHC magnets: a collaborative effort
Q1 and Q3 triplet magnets – US-AUP collaboration The first cryoassembly from US-AUP was delivered to CERN in November 2023 and will be re-tested at CERN in June 2024 (see figure 1, left). Production of the second cryoassembly was completed at Fermilab (see figure 1, right) and the completed assembly is ready for the horizontal…

WP3 contribution
INFN collaboration: High order correctors and D2 recombination dipole The last batch of the 54 high order corrector magnets was successfully tested in LASA by the end of 2022, and all correctors have been delivered at CERN. In February 2023, a celebration was held to mark the end of the first series production of HL-LHC…
