the Hadron Collider

The particle accelerator at CERN, the European Organization for Nuclear Research, has restarted after 14 months repairs as a result of severe damage occurring within days of it working. "Particle beams are again circulating in the particle accelerator powerful in the world, "reported a press release issued on the website of CERN.

CERN has started to work again at 21.00 GMT, a story that was described as a" milestone "in view of the Great Hadron Collider (LHC) will operate at full capacity, presumably in early 2010. When this happens the LCH is expected to produce hundreds of millions of frontal collisions of particles to near light speed. "It is fantastic to see the beam (of protons) circulating in the LHC again, "said the director general of CERN, Rolf-Dieter Heuer. Heuer noted that much remains to be done but stresses that this milestone are in the right direction.

helium leak

In September 2008, CERN scientists achieved amid a great celebration, a proton beam for the first time gave way around the accelerator, and shortly after I did another beam in the opposite direction .

But ten days later, a short and a helium leak caused a serious breakdown which led to costly and complicated repairs, not without incident, like a piece of bread dropped a bird in early November on electrical transformer outside the accelerator, and that nearly paralyze the process again.

However, following the launch of new LCH, Scientists hope that these situations do not recur. "The LHC is a machine much better understood than it was last year," said the director of the accelerators of CERN, Steve Myers. "We learned from our experience and developed technology that allows us to move forward. This is how it progresses," Myers emphasized.

If the evidence made the first proton beams around the accelerator ring will do well, it will progressively increase the power. Before Christmas, CERN scientists will witness the first collisions, an event for which, CERN has already said "not invite the press, and that only you will notice a statement.
