The progress since the last collaboration meeting in October 2021 has been impressive and the project passed several key milestones for the project implementation in spite of the turbulences caused by Covid-19 and the crisis in Ukraine.
The 4th Cost & Schedule Review (CSR) of the HL-LHC project was held at CERN from 11 to 13 November 2019. The review panel was composed as usual by CERN Machine Advisory Committee (CMAC) members and ad-hoc experts.
After having observed the first cases of illness in Italy and the following isolation measures, the coronavirus SARS-Cov-2, causing the severe respiratory illness COVID-19, became a subject of major concern in Europe during February 2020.
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.
