Abstract
The ATLAS detector is installed in its experimental cavernat Point 1 of the CERN Large Hadron Collider. During Run 2 of theLHC, a luminosity of ℒ = 2 × 103434 cm−2−2 s−1−1 wasroutinely achieved at the start of fills, twice the designluminosity. For Run 3, accelerator improvements, notably luminositylevelling, allow sustained running at an instantaneous luminosity of ℒ = 2 × 103434 cm−2−2 s−1−1,with an average of up to 60 interactions per bunch crossing. TheATLAS detector has been upgraded to recover Run 1 single-leptontrigger thresholds while operating comfortably under Run 3 sustainedpileup conditions. A fourth pixel layer 3.3 cm from the beam axiswas added before Run 2 to improve vertex reconstruction andb-tagging performance. New Liquid Argon Calorimeter digitaltrigger electronics, with corresponding upgrades to the Trigger andData Acquisition system, take advantage of a factor of 10 finergranularity to improve triggering on electrons, photons, taus, andhadronic signatures through increased pileup rejection. The innermuon endcap wheels were replaced by New Small Wheels with Micromegasand small-strip Thin Gap Chamber detectors, providing both precisiontracking and Level-1 Muon trigger functionality. Trigger coverage ofthe inner barrel muon layer near one endcap region was augmentedwith modules integrating new thin-gap resistive plate chambers andsmaller-diameter drift-tube chambers. Tile Calorimeter scintillationcounters were added to improve electron energy resolution andbackground rejection. Upgrades to Minimum Bias Trigger Scintillatorsand Forward Detectors improve luminosity monitoring and enable totalproton-proton cross section, diffractive physics, and heavy ionmeasurements. These upgrades are all compatible with operation inthe much harsher environment anticipated after the High-Luminosityupgrade of the LHC and are the first steps towards preparing ATLASfor the High-Luminosity upgrade of the LHC. This paper describesthe Run 3 configuration of the ATLAS detector.
