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.
The Microcosm garden features several large components of old CERN experiments.
