The installation of the beam pipe: a delicate surgical operation at the heart of the CMS experiment
Reaching another major milestone of the Long shutdown 2 and performing the biggest upgrade of the experimental beam vacuum system since the first operation of CMS in 2008. After several years of complex design, manufacture and planning, the CMS collaboration, in tight cooperation with experts of the CERN Technology Department-Vacuum, Surfaces, and Coating group, have…

The Forward Shielding upgrade: a real engineering challenge for CMS.
As for any other instrument, the CMS experiment needs a “quiet” environment to take data, with the lowest level of background noise.

Shielding the outer muon barrel chambers of CMS for HL-LHC : preparing an umbrella before the rain
CMS has just finished wrapping the barrel with a new layer which is not a new detector but a brand new protection system aimed to keep the outer barrel muon chambers shielded from background radiation present in the experimental cavern during collisions.

First GEM station (GE11) installed in CMS
Despite the rather challenging circumstances of the COVID-19 pandemic, the CMS GEM (Gas Electron Multiplier) team has been working against all odds to complete the installation of the very first GEM station (GE1/1) in CMS.
