Qualifying Magnets and Cavities at FREIA
Uppsala University in Sweden has been a valuable collaborator since the foundation of CERN. In the 1950’s, Uppsala, having just constructed its own cyclotron, contributed to the development of the very first accelerator at CERN: the synchrocyclotron. In the 1980’s CERN assisted Uppsala with the construction of a proton and heavy-ion accelerator and cooler-storage ring…

Update on Collaboration Agreements and Report from the Collaboration Board at the Last Annual Meeting
After the last Collaboration Meeting in Fermilab in October 2019, there have been several important developments in collaboration matters. The 2019 LIU/HL-LHC Cost and Schedule Review outcome was very positive with inclusion in the baseline of the various pending options that were all items to be procured via collaboration agreements. That allowed the settlement of…

Update on the Collaboration Members and Contributions
The 8th HL-LHC Collaboration Board took place during the last HL-LHC Annual Meeting in October 2018 at CERN. During the last months, several collaboration agreements have been prepared and are in the process of signature or advanced stage of finalization. – INFN for the production of the D2 cold masses. INFN is finalizing prototypes and…

Report on the CD2 DOE Review
The US HL-LHC AUP effort successfully defended its plans to DOE in December 2018, and was baselined in February 2019. This major step, called Critical Decision -2 approval (CD-2), provides the funding agency approval of the total estimated Project cost and yearly funding profile to meet the goal of the US contribution to HL-LHC. Two…

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…

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…

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…
