Abstract
Since the initial data taking of the CERN LHC, the CMS experiment has undergone substantialupgradesandimprovements. ThispaperdiscussestheCMSdetectorasitisconfigured for the third data-taking period of the CERN LHC, Run 3, which started in 2022. The entire silicon pixel tracking detector was replaced. A new powering system for the superconducting solenoid was installed. The electronics of the hadron calorimeter was upgraded. All the muon electronic systems were upgraded, and new muon detector stations were added, including a gas electron multiplier detector. The precision proton spectrometer was upgraded.
