The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. It is expected that it will address some of the most fundamental questions of physics, advancing humanity's understanding of the deepest laws of nature.
Location:The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground in a tunnel 27 kilometres (17 mi) in circumference, as much as 175 metres (574 ft) beneath.
LHC is a particle accelerator used by physicists to study the smallest known particles – the fundamental building blocks of all things. It will revolutionise our understanding, from the minuscule world deep within atoms to the vastness of the Universe.Two beams of subatomic particles called 'hadrons' – either protons or lead ions – will travel in opposite directions inside the circular accelerator, gaining energy with every lap. Physicists will use the LHC to recreate the conditions just after the Big Bang, by colliding the two beams head-on at very high energy. Teams of physicists from around the world will analyse the particles created in the collisions using special detectors in a number of experiments dedicated to the LHC. This analysis will may tell us the most desired truth in the world- the beginning of time and universe.
Recent Activities:
On 10 September 2008, the proton beams were successfully circulated in the main ring of the LHC for the first time, but 9 days later operations were halted due to a serious fault. On 20 November 2009 they were successfully circulated again, with the first proton–proton collisions being recorded 3 days later at the injection energy of 450 GeV per beam. After the 2009 winter shutdown, the LHC was restarted and the beam was ramped up to 3.5 TeV per beam, half its designed energy. On 30 March 2010, the first planned collisions took place between two 3.5 TeV beams, which set a new world record for the highest-energy man-made particle collisions.
