Video (4min 4sec): Large Hadron Collider: A Whistlestop Tour. Find out more about this giant machine and the experiments at the four sites where protons will be smashed together. "Deep under the border between France and Switzerland engineers are making the finishing touches to a giant machine that promises to change our understanding of physics.
"On September the Tenth, the Large Hadron Collider (LHC) will be switched on and the first beam of protons will spin around a twenty-seven kilometer ring. Protons start life above ground as Hydrogen gas atoms. They are striped of their electrons and they are injected into a succession of rings where they gather speed and gain energy.
"Eventually nearly 3,000 bunches of protons each containing a hundred billion particles will be injected into the LHC. The protons will circulate in a vacuum tube and will be steered around a 27 kilometer by over 9,000 magnets..."
