 microcosm is a museum of particle physics located at cern in the canton of geneva, switzerland, near the town of meyrin. it covers a broad range of particle physics topics, as well as the entire history of cern. exhibits include: * explanations of the purpose of cern and particle physics research in general. * a mock-up, hands-on version of rutherford's gold foil experiment * a real-time cosmic ray detector * a mock-up of the large hadron collider tunnel * models and explanations of current and future cern experiments * equipment from old experiments, including a large part of the ua1 detector, which ran at the super proton synchrotron at cern from 1981 to 1984, and helped discover the w and z bosons. == microcosm garden == the microcosm garden features several large components of old cern experiments. image:microcosm_garden.jpg|the entire garden image:big_european_bubble_chamber.jpg|the big european bubble chamber image:lep_rf.jpg|an rf cavity from the large electron-positron collider image:microcosm_initial_accelerator.jpg|initial stages of an old particle accelerator ==external links==  *cern microcosm webpage
