The Liquid Argon Calorimeters are employed by ATLAS for all electromagnetic calorimetry in the pseudo-rapidity region |η| < 3.2, and for hadronic and forward calorimetry in the region from |η| = 1.5 to |η| = 4.9. They also provide inputs to the first level of the ATLAS trigger. In 2022 the LHC started its Run-3 period with an increase in luminosity and pile-up of up to 60 interactions per...

The High-Luminosity Large Hadron Collider (HL-LHC) will enable a more detailed exploration of new physics phenomena by significantly increasing collision rates, leading to pileup levels of approximately 200 simultaneous interactions. The CMS experiment will add a new detector, the MIP Timing Detector (MTD) to cope with these challenges. The MTD is designed to mitigate pileup effects by...

While the  on-going Run-3 data-taking campaign will  provide twice the integrated proton-proton luminosity currently available at the LHC, most of the data expected for the full LHC physics program  will  only be delivered during the  HL-LHC phase. For this, the LHC  will undergo an ambitious upgrade program to be able to deliver an instantaneous luminosity of $7.5\times 10^{34}$ cm$^{-2}$...

482. The CMS Muon System Upgrade for High Luminosity LHC

To address the demanding conditions of increased luminosity and higher pileup expected during the high-luminosity phase of the LHC (HL-LHC), the muon spectrometer of the CMS experiment will undergo significant upgrades. These enhancements aim to ensure robust operation under challenging data-taking conditions while improving the tracking and triggering performance of the system.
