ATLAS event at 13 TeV - First stable beam, 3 June 2015 - run: 266904

Display of a proton-proton collision event recorded by ATLAS on 3 June 2015, with the first LHC stable beams at a collision energy of 13 TeV. Tracks reconstructed from hits in the inner tracking detector are shown as arcs curving in the solenoidal magnetic field. The yellow rectangles along with the red and green bars indicate energy deposits in the liquid argon and scintillating-tile calorimeters. Tracks originate from several vertices, indicating multiple proton-proton interactions (also known as pile-up ) recorded in one event.
