Beam sent from Large Hadron Collider after 14 months of repair
The world’s largest atom smasher, the Large Hadron Collider, has been re-started after 14 months of repairs.
The $10billion (£6billion) machine suffered a spectacular failure more than a year ago – just nine days after the launch.
Scientists are hoping the results from the device, which was designed to smash together beams of protons in a bid to recreate conditions after the Big Bang, will shed some light on the makeup of matter and the universe.
bout $40million (£24million) was spent on repair work. Progress on restarting the machine, on the border between Switzerland and France, went faster than expected on Friday.
The first beam circulated in a clockwise direction around the machine at about 10pm.
Two hours later the scientists circulated another beam in the opposite direction, which was the initial goal in getting the machine going again and moving it toward collisions of protons.
