WP3 contribution – Issue 6
The magnet program has reached several milestones since the last annual meeting: in the following we summarize the main achievements of our collaborations. The AUP progress on the MQXFA magnets is covered in a dedicated article (link). INFN collaboration and the D2 and corrector package cold masses The production of the 54 high order corrector…

Update on the HL-LHC Project Status – Issue 6
Progress since the last collaboration meeting in October 2021 has been impressive and the project passed several key milestones for the project implementation despite the turbulences caused by COVID-19 and the crisis in Ukraine. Among the many achievements, I would like to highlight here the successful endurance test validation of the MQXFA05 triplet quadrupole magnet…

Advancements in MQXFA program and endurance test
In May 2022, the HL-LHC AUP project successfully completed an endurance test on an individual magnet (MQXFA05) in vertical position. This step, foreseen for the final cold mass assembly in horizontal position, was anticipated to this intermediate assembly stage to gather more information on the long term behavior of Nb3Sn magnets. The test involved completing…

Overview of collaboration status and situation with Russian in-kind
The HL-LHC Project is entering the series construction phase and therefore most of the collaboration agreements are now focused on the production of final elements that will have their destination in the LHC tunnel and in the set of operational spares. The in-kind contributions account for about 10% of the total project cost, but at…

Planning of the 2021 Annual Meeting
Due to the COVID-19 restrictions last year, the 2020 annual meeting initially planned to take place in Uppsala had to be postponed and instead the 10th HL-LHC Collaboration Meeting was held in virtual form and limited to plenary sessions. While some uncertainty remains, we are more optimistic this year. We are therefore pleased to announce…

HL-LHC Industrialization
The High-Luminosity Project is nowadays in the transition from the prototyping phase into full construction mode and most of the activities in view of the series production for the HL-LHC hardware have already started. Procurement and industrialization are closely following the natural evolution of the project and are running in parallel to the project milestones.…

Preparation of the C&S Review 2021
At the request of the management of CERN, four extensive Cost and Schedule Reviews (CSR) of both the LIU and the HL-LHC projects were carried out in March 2015, October 2016, March 2018, and November 2019. An international panel of experts, headed by the CERN Machine Advisory Committee chairman and composed by the CMAC members…

Update on Collaboration agreements and report from the Collaboration Board at the last Annual Meeting
The still unresolved COVID-19 pandemic, which defined the year 2020, has unsurprisingly had an impact on our collaborations. However, the impact appears to be contained to a few months, with delays that can be reabsorbed and are also partially mitigated by the decision taken after the 2019 C&SR to delay the start of LS3 by…

Status of civil engineering works
In spite of the perturbation related to the COVID-19 pandemic, the civil engineering works is progressing well. Figure 1 shows the civil engineering status. At Point 1, the final lining of the underground structures is fully completed and the installation of metallic structures, concrete modules, separation walls and safe rooms in the cavern and in…

Implementation of crystal collimation of heavy ion beams for Run3 in absence of 11 T dipoles
Following the recommendation of the C&SR 2019, crystal collimation was successfully integrated in the WP5 upgrade baseline as an in-kind item to mitigate schedule issues with the 11 T dipoles which have shown potential reliability issues for long-term operation in the accelerator. A detailed investigation program is currently underway to understand the root cause of…
