ATLAS is a general-purpose detector at the Large Hadron Collider (LHC), located at the Center for European Nuclear Research (CERN) in Geneva, Switzerland. It investigates a wide range of physics, from the search for the Higgs boson to extra dimensions and particles that could make up dark matter. The interactions in the ATLAS detectors create an enormous flow of data. To reduce the data volume, ATLAS uses an advanced “trigger” system to tell the detector which events to record and which to ignore. The Yale teams analyze data from ATLAS and are part of the ATLAS leadership in physics, operations and the upgrade. Yale is a Trigger and Data Acquisition Institute with design and validation responsibilities, and Yale constructs staves and performs sensor R&D for the ATLAS tracker upgrade.
