OPAL was one of the major experiments at CERN's Large Electron–Positron Collider. OPAL studied particles and their interactions by collecting and analysing electron-positron collisions. There were over three-hundred physicists from 32 institutions involved in the collaboration.[1]

LEP was the largest particle accelerator in the world. OPAL was one of four detectors associated with LEP, alongside ALEPH, DELPHI and L3.[2]
