The challenge of Run3: CMS is preparing to resume its operations for the Run-3 of the Large Hadron Collider (LHC) after a 3-year long shutdown called LS2 (2019-2021). The time of LS2 was used to perform upgrades, which are regularly conducted in the…

As for any other instrument, the CMS experiment needs a “quiet” environment to take data, with the lowest level of background noise. In the CMS detector, background noise is mainly due to energetic particles generated at high eta (i.e. close to the…
