002946595 520__ $$aA visualization of an event recorded by the ATLAS experiment (run 508073, event 22881991) on October 8, 2025, when the Large Hadron Collider accelerator was providing proton-proton collisions at 13.6 TeV with a "high-mu" setup. In a "high-mu" setup, the proton beams in the accelerator are focused and directed to produce a high number of collisions per bunch crossing. The event visualized here was recorded in a collision with an average of 150 proton-proton interactions, and 92 primary vertices were reconstructed.

In the background, a part of the muon spectrometer (the New Small Wheel, NSW) is visible; the other parts of the detector have been hidden for a clearer view of the interaction point. Starting from the center, the image displays the 92 primary vertices (blue spheres) inside the beam pipe. From each primary vertex, many different particles are produced. The tracks of the charged particles, reconstructed by the inner detector, are shown as orange lines. In total, more than 3800 tracks are reconstructed in the proton-proton interaction.

The top left view shows a transversal view of the event, where, from the center, the tracks of the charged particles as reconstructed in the inner detectors are shown (multicolor lines) as well as the energy deposits (yellow bars) in the electromagnetic and hadronic calorimeters. A blue line shows the reconstructed track of a muon. The bottom view shows the same event in a longitudinal projection, where the reconstructed 92 primary vertices are also shown, visualized as white spheres. The right view shows the energy deposits in the calorimeters represented on a projected surface of the ATLAS detector; this kind of plot (called a "Lego plot") shows the overall activity of an event.
