ATLAS Event Display: 13.6TeV collisions with view of New Small Wheel Detectors (NSW)

Event display (Run 427514, Event 68319093) of a collision event recorded in ATLAS on 7 July 2022, when stable beams of protons at the energy of 6.8 TeV were delivered to ATLAS by the LHC. The red line shows a muon candidate with transverse momentum of 15 GeV reconstructed using information from the inner tracking detectors and the ATLAS Muon Spectrometer end-cap. The muon candidate was among the first reconstructed using hits in the Micromegas (MM) chambers of the New Small Wheel (NSW) on side C. The NSW, installed during the long shutdown between Runs 2 and 3, is outlined in white and the MM hits are shown as orange lines. Additional muon chambers associated with the track are shown as green (MDT endcap) and purple (TGC endcap) boxes. Also shown in the figure are the tracks of charged particles as they are reconstructed in the inner detector (orange tracks), as well as the energy deposits in the electromagnetic (green boxes) and hadronic (yellow/orange boxes) calorimeters. The bottom-left view is a projection of the same event onto the transverse plane, showing in addition the hits in the TRT detector in white (red) for hits (high-threshold hits).
