Abstract: The High-Luminosity LHC (HL-LHC) era, set to begin in 2029, will provide the general-purpose experiments with an instantaneous luminosity of up to \(\mathcal{L}=\text{7.5}\times\text{10}^\text{34}\,\text{cm}^\text{$-$2}\,\text{s}^\text{$-$1}\) from pp collisions at a centre-of-mass energy of 14 TeV. To fully exploit this unprecedented data set, the experimental setups must be upgraded to withstand the challenging conditions of the HL-LHC, including up to 200 simultaneous collisions per bunch crossing and a substantial radiation dose delivered to the detectors. The CMS collaboration is currently undertaking the Phase-2 upgrade, which aims to enhance the detector's capabilities to maintain high performance under these conditions. This upgrade includes significant improvements to the muon spectrometer and barrel calorimeter, a complete replacement of the silicon tracker, endcap calorimeter and beam radiation and luminosity subsystems, the introduction of a new MIP timing detector layer, and a redesigned trigger and data acquisition system. These enhancements will ensure that the CMS experiment can fully profit from on the HL-LHC data, maximising its physics potential and expanding its ability to make the most precise measurements.
