Argonne National Laboratory has contributed to the ATLAS experiment at CERN’s Large Hadron Collider for over 30 years, assisting in the design, construction, and upgrades of the ATLAS detector. The detector, which started data recording in 2009, weighs approximately 8,000 tons and utilizes over 100 million sensors to analyze particle collisions.

Argonne researchers have developed advanced technologies for data processing and are currently upgrading crucial detector components in preparation for the HL-LHC project, which will increase data output by twenty-fold. The collaboration is also adapting ATLAS-related code for exascale computing systems, particularly the Aurora supercomputer, to enhance data analysis capabilities. The ATLAS experiment aims to further explore particle physics and potential discoveries beyond the Standard Model, including dark matter.
