Our exhibition features 34 fascinating exhibits, including retired silicon strip and pixel detectors, trigger front-end boards, calorimeters, and scale models of the ATLAS and CMS experiments at CERN. You’ll gain insights into the three major detectors at the Large Hadron Collider—ATLAS, CMS, and LHCb—as well as groundbreaking experiments like Super-Kamiokande for neutrinos, ZEPLIN I and II for dark matter at Boulby, and the Muon Ionisation Cooling Experiment at ISIS.
The tour also includes a look at the ATLAS Inner Tracker (ITK) clean room from the outside and showcases advanced detector technologies that power modern particle physics. Whether you’re curious about the universe’s smallest components or the technology behind world-class experiments, this is your chance to see science in action!
