ATLAS-PHOTO-2024-050-2  -  Small, Medium, Large, Original
Event display of a heavy ion collision event (Run number 488915, Event number 451524684) recorded in ATLAS on the 6th of November 2024, when stable beams of lead ions colliding at a centre-of-mass energy per nucleon pair of 5.36 TeV were delivered to ATLAS by the LHC. The image shows a cut-out view of the ATLAS detector, where some sub-detectors and some sectors have been removed for visualization purposes. Starting from the point where the two beams of lead ions from the LHC collide, the image shows the tracks of charged particles as reconstructed in the inner detector (visualized as orange lines) and the energy deposits in the electromagnetic (green/teal cells) and hadronic (yellow/orange boxes) calorimeters.

Event display of a heavy ion collision event (Run number 488915, Event number 451524684) recorded in ATLAS on the 6th of November 2024, when stable beams of lead ions colliding at a centre-of-mass energy per nucleon pair of 5.36 TeV were delivered to ATLAS by the LHC. The figure on the top left shows a transverse view of the ATLAS detector. The figure on the middle right shows the energy deposits in the cells of the ATLAS calorimeter. The figure at the bottom shows a side view of the ATLAS detector. Starting from the centre of the ATLAS detector, the reconstructed tracks of the charged particles in the inner detector are shown as coloured lines. The energy deposits in the electromagnetic (the green layer) and hadronic (the red layer) calorimeters are shown as yellow boxes. The hits in the muon spectrometer (the outer blue layer) are shown as red and grey blocks.
