The Large Hadron Collider was shutdown in 2013 for a major refit.

　　It's allowed for its power to be doubled, enabling scientists to probe into the so-called "dark universe" that lies beyond the visible one.

　　Laurette Ponce is the Chief Engineer at CERN.

　　"Now we have just managed to do the first turn with the anti-clockwise beam, the beam 2. We have been striding the beam all along the ring and we managed to keep it for 25 turns already without the RF capture, so this is already a big success."

　　The refit will allow particle beams to travel through the Large Hadron Collider at just below the speed of light.

　　Testing of the updated Collider is set to begin in around a month.

　　Scientists at CERN say they hope the updated Collider will help them push the boundaries of science beyond the current Standard Model of particle physics.
