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…

HL-LHC Crab Cavity Cryomodules – UK Collaboration Status
The first LHC crab cavity cryomodule build with the two qualified cavities from CERN is progressing well at Daresbury Laboratory. The DQW cryomodule is the first of four series cryomodules being built by the UK collaboration, following the RFD-SPS delivery, with a fifth DQW cryomodule to be built by CERN. Since the RFD build, the…

DQW Series Production Status – CERN & Research Instruments (RI)
The series DQW cavities manufactured at RI (eight cavities) and CERN (two cavities) have progressed significantly over the period of 2024-25. Two cavities, one from RI and one from CERN, were fully qualified with higher order mode (HOM) couplers in their final state well beyond the specification (4.7 MV) and sent to UK-STFC for cryostating…

RF Dipole Cryomodule for SPS Tests (CERN & UK)
The RF dipole prototype cryomodule foreseen for tests with beam in the SPS tests was successfully repaired and commissioned in the SM18 facility at CERN in 2024. During the year-end technical stop (YETS) 2024-25, the cryomodule was installed in the SPS-LSS6 bypass dedicated to the crab cavity tests in the SPS. Immediately after the installation,…

Beam instrumentation put to the test
Although most of the HL-LHC beam instrumentation work package is well into production and even integration, some of the more innovative designs are also taking advantage of the final beams in Run 3 to test and optimise their performance. In particular, an electro-optical beam position monitor (e-o BPM) and a Beam Gas Curtain (BGC) profile…

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 the series HL-LHC DQW cryostating & infrastructure preparations
Two series dressed DQW cavities have been qualified at CERN and are being prepared for shipment to STFC in the UK for string assembly. Meanwhile, since the completion of the RFD SPS cryomodule in October 2023, the UK team at Daresbury Laboratory have been preparing for the series DQW cryomodules; upgrading infrastructure, updating assembly tooling,…

Promising results from HL prototype beam instruments
In the framework of the HL-UK2 collaboration, two novel beam instrument technologies are currently under development. The first is a non-invasive beam imaging system, known as the Beam Gas Curtain (BGC), which observes beam-induced fluorescence produced when charged particles interact with a thin gas jet. The second is a high-bandwidth beam position monitor designed to…
