particle detectors at CERN in Geneva, a stone's throw from Big Bang
process almost recreated in the laboratory
The largest particle accelerator world Cern in Geneva has reached the maximum almost never touched able to collide two beams of protons to create conditions similar to those of Big Bang which gave birth to the universe. The Large Hadron Collider , which runs for 27 km under the border between Switzerland and France, has generated seven trillion of elettrovolt. The LHC, which opened in 2008, he was stopped for 48 hours after a fault.
And so, after two failures that occurred in the early hours of the day, the protons at the time of the clash have traveled at a speed close to that of light. Now researchers, who will analyze the data collected, turn off the LHC to switch back on after maintenance work and expansion that will last almost a year. At that point the power will be doubled to 14 TeV, a level that comes close to those more experienced in the first instants of the Universe.
The Large Hadron Collider is the largest particle accelerator ever built and has so far had a rather unfortunate. Opened September 10, 2008, just 36 hours after it was shut down for failure due to a faulty electrical connection between two of the superconducting magnets of the machine. In the subsequent repair work has been accommodated another 53 defective magnets.
With the LHC scientists (among whom there are many Italians that the latter rappsentano lenders and the second scientific community at CERN) have the objective of verifying the existence of smaller particles and elusive, like the famous Higgs boson , dubbed the "God particle", and understand the nature of matter and of 'energy "dark" that are respectively 23% and 72% of the universe. The visible matter and energy account for only 5% of the total universe.
