Large Hadron Collider (LHC)


The Large Hadron Collider (LHC) is the world’s largest and highest-energy particle accelerator.The main aim to develop this huge machine is to collide opposing particle beams, of either protons at an energy of 7 TeV per particle, or lead nuclei at an energy of 574 TeV per nucleus. The Large Hadron Collider was built by the European Organization for Nuclear Research (CERN).It lies in a tunnel 27 kilometres (17 mi) in circumference, as much as 175 metres (570 ft) beneath the Franco-Swiss border near Geneva, Switzerland.




  • The LHC experiments could reveal the origins of mass, shed light on dark matter, uncover hidden symmetries of the universe, and possibly find extra dimensions of space.


  • For most of their split-second journey around the ring, the beams travel in two separate vacuum pipes, but at four points they collide in the hearts of the main experiments, known by their acronyms: ALICE, ATLAS, CMS and LHCb.


  • The data recorded by each of the big experiments at the LHC will fill around 100 000 dual layer DVDs every year


  • At full power, trillions of protons will race around the LHC accelerator ring 11 245 times a second, travelling at 99.99% the speed of light.


  • The total cost of the project is expected to be €3.2–6.4 billion
