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…

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…

Machine protection: series-production of Quench Heater Discharge Power Supply units well underway
The first batch of 48 series-production Quench Heater Discharge Power Supply (DQHDS) units, provided as an in-kind contribution by KEK, Japan, has just arrived at CERN. These units feature a new design developed by CERN for the HL-LHC upgrade and will operate together with the Coupling-Loss Induced Quench (CLIQ) systems to protect the HL-LHC inner…

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…

Quench heater power supplies: signature of in-kind contribution and completion of four pre-series units
The Quench Heater Discharge Power Supplies (DQHDS) are essential magnet protection devices in the Large Hadron Collider (LHC), ensuring the safety and integrity of superconducting magnets since their initial deployment in 2007. Triggered by the detection of a magnet quench (the local, sudden transition from a superconducting to normal state), these devices release energy into…

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…

Overview of Collaboration Status 2024
The HL-LHC Collaboration Office continues to update existing collaboration agreements and put in place new agreements with HL-LHC partners. Since the previous HL-LHC Collaboration Board Newsletter, the Collaboration Office has focused on the signing of the UK Phase 1 agreements, allowing for final invoicing to take place. The main deliverable expected for the UK Phase…
