Cern draws up plans for collider four times the size of Large Hadron

The Future Circular Collider would smash particles together in a tunnel 100km long

Plans for a machine that would dwarf the Large Hadron Collider have been drawn up by researchers at Cern to take over the baton in the search for new physics in the latter half of the century.

The a20bn (17.8bn) machine, named the Future Circular Collider, would smash particles together inside a 100km (62 mile) tunnel, making it four times the size of the LHC, which at present is the largest scientific instrument on the planet.
