Summary of the TCC Day and New Schedule as Agreed on during November Meeting in 2019
In an effort to further enhance the communication and transparency of activities having potential dependencies in terms of schedule or resources on other HL-LHC WPs, a first TCC day was organised on 12th March 2020. The meeting was also the occasion to commonly discuss all further opportunities of descoping and to assess the consequences of…

First Tests of Full Remote Handling for VAX Modules
Today’s LHC environment is subject to different radiation types, particle types and energy ranges. In particular, at the machine-experiment regions the main sources of radiation come from beam collisions at experiments and beam interactions. The 10-fold increase of luminosity (collisions in the experiments) foreseen for HiLumi will increase the radiation levels, and innovative approaches need…

COVID-19 Impact on Schedule and Update on Civil Engineering Works
The COVID-19 restrictions have impacted the schedules of the LS2 and of the HL-LHC activities. Concerning the LS2 schedule, the hardware commissioning of LHC should be completed by March 2021 for all sectors except the S67, where the installation of the first 11-T dipole cryo-assembly is foreseen during the first quarter of 2021, postponing the…

Report from the November Cost & Schedule Review
The 4th Cost & Schedule Review (CSR) of the HL-LHC project was held at CERN from 11th to 13th November 2019. The review panel was composed as usual by CERN Machine Advisory Committee (CMAC) members and ad-hoc experts. The goal of this fourth CSR was to assess the development of the baseline since the first…

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 Civil Engineering Work for HL-LHC
The two civil-engineering contractors, MARTI for the Point 1 works and IMPLENIA for the Point 5 works, are fully mobilized. The excavations of the shafts at Points 1 and 5 were completed in February 2019 and December 2018, respectively. The shaft excavation were performed during the LHC physics Run2, with very minor impacts on the…

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…
