The ATLAS experiment is a large detector system developed by a collaboration of physicists from around the world to study very-high-energy proton-proton interactions at the Large Hadron Collider (LHC) at CERN, a laboratory for high energy physics near Geneva, Switzerland. Boston University personnel were involved in the construction and installation of the muon detectors for ATLAS. The detectors occupy a region the size of a five-story building and measure the trajectories of muons in a magnetic field with a precision of better than 1/10 of a millimeter. This permits precise determination of the muon momentum which is an important ingredient in searches for new phenomena at the TeV energy scale. Boston University has also played a leading role in the development of computing and analysis tools.
