LHC accelerator at CERN in Geneva

Diagram of the LHC (Large Hadron Collider) accelerator at CERN in Geneva. The LHC is an enormous accelerator built in a 27 km-long circular tunnel. The tunnel is situated underground at a depth ranging from 50 to 175 metres on the outskirts of Geneva, beneath the Franco-Swiss border. The LHC accelerates two beams of particles in opposite directions around a circular ring. The beams are made to collide in four points along the ring, inside  the four experiments ATLAS (A Toroidal LHC ApparatuS), CMS (Compact Muon Solenoid), LHCb and ALICE (A Large Ion Collider Experiment). The beams of particles can be of heavy ions (in 2010 experiments were carried out with lead ions) or subatomic particles (protons). Source: http://lhc-machine-outreach.web.cern.ch
