CERN, Meyrin, Switzerland

Physics detectors are developed to understand the evolution and structure of nuclear matter from the smallest quarks and gluons to the elements in the Universe created by stars. The ALICE Detector at CERN was designed to open a new high-energy frontier in the physics of ultra high-density hadronic matter and the Quark Gluon Plasma (QGP). The Berkeley Lab designed the Electromagnetic Calorimeter and fabricated 18 supermodules weighing 8 tons each.
