Update on the HL-LHC Project Status – Issue 4
Dear HiLumi collaborators, The period following the 9th Collaboration Meeting in Fermilab, 14-17 November 2019, has been exceptionally rich in events. The most striking has certainly been the COVID-19 emergency, with long periods of lockdown almost everywhere. Although work has resumed at CERN and in most laboratories, the consequences go far beyond the lockdown time.…

Update on the HL-LHC Project Status – Issue 3
As mentioned in the closing remarks of the 8th HL-LHC Annual Meeting held at CERN (18th October 2018), the project is experiencing a mix of success and difficulties while passing from design and industrialization into construction. The most delicate point is certainly the unexpected bad behaviors of some prototypes and model magnets. The HL-LHC magnets…

Highlights from the HL-LHC Work Packages
WP2: Performance and Beam Dynamics During a measurement campaign in 2017 at the LHC, it was clearly demonstrated for the first time the beam lifetime improvement due to a compensation of the beam-beam long range effects, using DC current baring wires. The measurements and design studies are continuing during 2018 for further refining of the…

Summary on the outcome of the 2018 Chamonix meeting
The 2018 Chamonix workshop featured three sessions for the HL-LHC project. The sessions at Chamonix provided the first chance for a technical and performance review of the project following the re-baselining in 2016. The CMAC validated all re-baselining decisions from 2016 and gave the project a good bill of health. Main observations from Chamonix 2018…

Outcome of the 2018 Cost and Schedule review
The 3rd Cost & Schedule Review of the projects HL-LHC and LIU (LHC Injectors Upgrade) was held at CERN on 26th – 28th of March 2018. As usual, the panel is composed by the CMAC (CERN Machine Advisory Committee) members with the addition of a few other international experts as reviewers. The main outcome was…

Update on the Collaboration Partners and Contributions
The 7th HL-LHC Collaboration Board took place during the 7th HL-LHC Annual Meeting in November 2017, jointly organized by CIEMAT and CERN in Madrid, Spain. One of the focuses of the 7 th HLCB meeting was a summary of the existing agreements for in-kind contributions from collaborators. Since the HLCB meeting in Paris, the project…

Highlights from the HL-LHC Work Packages
WP2: Performance and Beam Dynamics Following the project re-baselining in summer 2016, the layout and optics of the high luminosity insertion regions were reviewed and the performance re-evaluated. This has led to a small but visible reduction in performance, reducing the margins available for the achievement of the nominal and ultimate luminosity targets. Optimization of…

Summary on the outcome of the 2017 Chamonix and the 28th USLARP meeting in Napa in April
The 2017 Chamonix workshop featured three joint sessions between the HL-LHC and the LIU project. The main observations from Chamonix 2017 relevant for the HL-LHC project were: A complete summary of the Chamonix 2017 workshop by the CERN Director of Accelerators, Frederick Bordry, can be found here. The 28th USLARP meeting in Napa in April…

Project Planning and EVM
The implementation of the EVM (Earned Value Management) system for the HL-LHC project was ready for the 2nd Cost & Schedule Review (CSR) that was held in October 2016. This tool tracks, among other things, the schedule and cost variances of the project with respect to estimates made by the project team at the time…

3rd HiLumi Industry Day in the UK
The third edition of the HiLumi Industry Day took place in Warrington, a few minutes away from Daresbury Laboratory, in May 2017. This two-day event jointly organised by CERN and STFC gathered some 200 participants from 17 European countries. Some key engineers and physicists from CERN and STFC presented the technical challenges of the HL-LHC…
