The 27 km circular lab Large Hadron Collider located near Geneva, world’s biggest particle collider that went offline in February, has double its power and will reopen in March, to help scientists learn more about the Higgs boson.

Last year the Large Hadron Collider made one of the greatest discoveries in the history of science!
The LHC was built in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories. It lies in a tunnel 27 kilometres (17 mi) in circumference, as deep as 175 metres (574 ft) beneath the Franco-Swiss border near Geneva, Switzerland.
As of 2014, the LHC remains the largest and most complex experimental facility ever built. Its synchrotron is designed to collide two opposing particle beams of either protons at up to 4 teraelectronvolts (4 TeV or 0.64 microjoules), or lead nuclei at an energy of 574 TeV (92.0 µJ) per nucleus (2.76 TeV per nucleon), with energies to be roughly doubled to around 7 TeV (14 TeV collision energy) —more than seven times any predecessor collider—by around 2015. Collision data were also anticipated to be produced at an unprecedented rate of tens of petabytes per year, to be analysed by a grid-based computer network infrastructure connecting 140 computing centers in 35 countries (by 2012 the LHC Computing Grid was the world’s largest computing grid, comprising over 170 computing facilities in a worldwide network across 36 countries).
