The Atlantis event display is a visualization program [1] [2] for the Atlas experiment, the largest, general-purpose particle detector experiment at the Large Hadron Collider (LHC), a particle accelerator at CERN (the European Organization for Nuclear Research) in Switzerland[3].

Atlantis implements 2D data-orientated projections [1] which can help understand proton-proton collision events. Event data are stored in XML files produced by a dedicated algorithm running in the ATLAS software framework, and translated into internal data objects. Multiple views of the data can be displayed within the main canvas area, with varying size and position. Interactions such as zoom, selection and query can occur between these views using drag and drop. The Atlantis program is implemented in Java.

Atlantis Java libraries are used in the Minerva program [4], a tool developed to help students learn more about the ATLAS experiment and particle physics at CERN.


The ATLANTIS event display is used by physicists as a standalone tool (from a downloadable jar file). Images created by ATLANTIS are usually embedded into physics papers to illustrate the results of particle collisions. The event display is also used in the Control Room of the ATLAS experiment during LHC collisions. This helps understand the quality of collected data in real time.
