The HL-LHC Cold Powering Systems transfer the current from the power converters, located in the new underground galleries, to the new superconducting magnets of the HL-LHC Inner Triplets and Matching Sections at P1 and P5
While the HL-LHC era for proton collisions starts in 2029 with the operational Run 4, the aim is to achieve the target HL heavy-ion performance already in Run 3 following the upgrade of the ALICE experiment during LS2.
The last batch of the 54 high order corrector magnets was tested in LASA by the end of 2022, and all correctors have been delivered at CERN. In February 2023, a celebration was held to mark the end of the first production of HL-LHC magnets.
The first test of superconducting crab cavities to rotate a beam of protons was performed on 23 May 2018 using a beam from CERN’s Super Proton Synchrotron (SPS) accelerator. These cavities are a key component of the HL-LHC.
The progress since the last collaboration meeting in October 2020 has been truly remarkable and the project successfully passed several key milestones for the project implementation in spite of the COVID-19 restrictions.
After the last Collab. Meeting in Fermilab in Oct. 2019, there have been several important developments in collaboration matters. The 2019 LIU/HL-LHC C&SR outcome was very positive with inclusion in the baseline of the various pending options
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.
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.
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.
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.
