Eight years ago in 2012, at the largest International Conference on High Energy Physics, the discovery of a new particle carefully coined as Higgs boson-like was announced by the ATLAS and CMS Collaborations.
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.
When visitors at CMS enter the cavern and see the detector in all its beauty, they often ask how it has been possible to fit everything together and to make it work as a singular instrument.
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.
Since late May, with the incremental re-opening of CERN’s facilities, members of the CMS GEM project have been hard at work restarting the laboratory activities in preparation for the continued efforts towards the GE1/1 chambers installation.
The CMS experiment at CERN is happy to announce a new batch of open data from the Large Hadron Collider (LHC), this time encompassing all the data recorded by CMS in 2011.
