Description

Precise and efficient muon detection is essential for a wide range of physics analyses performed with the ATLAS experiment at LHC. The excellent performance of the ATLAS Muon Spectrometer (MS) during LHC Run-1 and Run-2 has been demonstrated by the large number of physics results, in which muon triggering and reconstruction played a central role. For LHC Run-3 and in view of the High-Luminosity LHC era, significant detector upgrades were implemented, most notably the installation of the two New Small Wheels (NSW), in the innermost stations of the MS endcaps. The ATLAS MS now comprises both legacy gaseous detectors—Monitored Drift Tubes (MDT), Thin Gap Chambers (TGC), and Resistive Plate Chambers (RPC)—which have been in operation for over 15 years, and the two new technologies Micromegas and small-strip TGCs in the NSW. This presentation will cover the performance of all detectors of the ATLAS MS and muon trigger system. Particular emphasis will be given to the new detectors. The results will be presented in the context of the related physics studies and will include measurements of muon trigger and identification performance.
