Make rainy days something to look forward to with a high-energy event display from the ATLAS detector at CERN
The umbrella features the cunningly-named "Event 1273922482, Run 280673". This is the highest-mass central dijet event from 2015 data taking with the ATLAS detector, which records the aftermath of proton collisions from the Large Hadron Collider at CERN. The two central, high-pT jets (green and yellow shards) have an invariant mass of 6.9 Tera- electronVolts (TeV). The length of these shards indicates the amount of energy detected by the ATLAS energy calorimeters.
The blue/grey octagon (or hexadecagon) shows a cut-away of the ATLAS detector structure, and the yellow starburst and blue droplets in the centre of the display show the tracking and hits detected by millions of silicon strips and gas-filled straws in the heart of the detector.
