Description

The instantaneous luminosity of the Large Hadron
Collider at CERN will be increased by about a factor
of five with respect to the design value by
undergoing an extensive upgrade program over the
coming decade. The largest phase-1 upgrade project
for the ATLAS Muon System was the replacement of the
first station in the forward regions with the New
Small Wheels (NSWs) which took place during the long-
LHC shutdown in 2019-2021.
The two Small Wheels are called A and C and cover a
positive and negative pseudorapidity acceptance in
the range |η| =1.3 to 2.7. Both Small Wheels have
been successfully installed in ATLAS in 2021 and took
data from p+p collisions at 13.6 TeV in 2022.
Along with resistive strips Micromegas, the NSW's is
equipped with eight layers of small-strip thin gap
chambers (sTGC). The new system is designed to assure
high tracking efficiency, reduction of fake trigger
rates and precision measurement of muon tracks. In
this presentation we will discuss the performances of
the sTGC detectors from data taken with the first LHC
beam in 2022 and 2023.
