This is the story of the ATLAS New Small Wheel detectors. These new muon detectors were successfully installed in the ATLAS Experiment in 2021, following nearly a decade of design and construction, and marking a major milestone in ATLAS’ high-luminosity era.
The High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) will dramatically increase the rate of collisions in the ATLAS experiment. While an opportunity for physicists to explore some of the rarest processes in the Universe, the large collision rate brings new challenges – in particular, higher radiation levels and significantly more data. The ATLAS Collaboration is adapting its experiment to deal with these challenges, upgrading all parts of its detectors with new, state-of-the-art instruments.
The Muon New Small Wheels are the first new detectors in ATLAS specifically designed to handle high luminosity conditions. This installation of the second – and final – NSW follows nearly a decade of dedicated efforts from ATLAS members, who designed, constructed and assembled this high-tech muon detector from scratch. These new detectors will significantly expand the ATLAS experiment’s capabilities, readying us for the exciting high luminosities to come.
