On November 30, 2009, CERN restarted the experiments at the Large Hadron Collider (LHC). This gallery offers a look at five of the LHC’s six experiments: ALICE, ATLAS, CMS, LHCb, and TOTEM.
Here’s a rendering of the ALICE detector.
Size: 26 m long, 16 m high, 16 m wide
Weight: 10 000 tonnes
Design: central barrel plus single arm forward muon spectrometer
Location: St Genis-Pouilly, France.
