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…

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…

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 with series production of DFHX/M by the University of Uppsala and DFX/M by the University of Southampton
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 at Point 1 and Point 5. Eight systems plus two spares of each of the two different types – ‘X’ for the inner triplets; ‘M’…

Start of Series production of DFHX/M by RFR
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 at Point 1 and Point 5. Eight systems of two different types will be installed in the HL-LHC underground as from mid-2027. Each of these…

The DFH Cold Boxes produced in a CERN–FREIA/Uppsala University collaboration involving the Swedish RFR industrial company
This collaboration concerns the cryostat devices that will house and connect the HTS REBCO current leads to the MgB2 Superconducting Links powering the HL-LHC magnets. Nine cryostats (4 DFHX for the inner triplets and 5 DFHM for the matching section magnets) are to be manufactured. The fabrication of the cryostats is based on a “build-to-print”…

Fruitful Development Using a New Superconductor
An important milestone was achieved in June 2020 with the successful test at CERN of a demonstrator – Demo 2 – of the cold powering system for the HL-LHC magnets. Demo 2 incorporates a superconducting 60-m long power transmission line, the Superconducting Link, which will later be used to connect the HL-LHC magnets in the…

Production Readiness reviews
Two production readiness reviews where conducted at CERN: one for the pressure vessels and one for the MgB2 cable production. The pressure vessel review covered the scope and interfaces, quality assurance, manufacturing and inspection plan, documentation procedures, production schedule and associated resources. In general, everything is well defined and only some improvements to be made…

DFX review and design modifications
On the 31st January 2019 (with a 2nd final session on the 12th February), a DFX Conceptual Design Review was held at CERN. The DFX (Distribution Feed Box) is a key element of the cryogenic powering line for the new magnets of the LHC interaction regions at IP1 and IP5. This powering line, the so-called…
