The Large Hadron Collider is the largest and most complex machine ever built, so it is very difficult to assess its scale.
The collider consists of seven detectors:
- ALICE (A Large Ion Collider Experiment)
- ATLAS (A Toroidal LHC ApparatuS)
- CMS (Compact Muon Solenoid)
- LHCb (The Large Hadron Collider beauty experiment)
- TOTEM (TOTal Elastic and diffractive cross section Measurement)
- LHCf (The Large Hadron Collider forward)
- MoEDAL (Monopole and Exotics Detector At the LHC).
These underground nodes form a 27 km (17 miles) ring.
The video provided by the staff of the ALICE section shows a brief video tour of the detector. ALICE, which weighs more than the Eiffel Tower, has the largest magnet on the planet, designed to study the collisions of heavy ions, in particular collisions of Pb-Pb nuclei at an energy in the center-of-mass system of 2, 76 TeV per nucleon.
