The Large Hadron Collider (LHC) being built at CERN is nearing completion.
The LHC is being constructed 100 metres underground in a 16-mile long circular tunnel, running under the Franco-Swiss border. Inside the tunnel two particle beams will be accelerated to extremely high energies, and will crash into each other forty million times a second, creating a snapshot of conditions that existed billionths of a second after the ‘Big Bang’. ATLAS, the culmination of 15 years’ work by over 150 European institutions, aims to find the Higgs particle that holds the key to understanding the origin of mass.
The existence of the Higg's boson was hypothesized almost 50 years ago, and the LHC may finally be able to detect it.The conditions that will be reproduced at LHC will correspond to approximately 1/10,000,000,000 of a second after the ‘Big Bang’ when the temperature was 1,000,000,000,000,000 degrees. Large detectors will electronically register the movement and position of charged particles allowing physicists to analyse the reactions that created
them.
