Large Hadron Collider hibernates after wrong sort of big bang caused by hellion leak, to re-awaken in Spring'09
(quote)
Two weeks ago, the most powerful atom smasher to be built had been switched on to global acclaim and scientists were ready to begin experiments that could unlock many of the enduring mysteries of the Universe. They are going to have to wait a little longer. On Friday the Large Hadron Collider (LHC) created the wrong sort of big bang - a fault so serious that CERN, the European Organization for Nuclear Research, announced last night that the particle accelerator would have to be shut down until next spring for repairs.
Preliminary investigations into the incident, in which a huge quantity of helium leaked from the LHC’s cooling system, have suggested that it was caused by a faulty electrical connection between two of its superconducting magnets. The fault affected a part of the accelerator that is kept chilled to within 1.9C of absolute zero, and it will have to be warmed up to room temperature before the problem can be understood fully and resolved. It will take at least three to four weeks to warm the affected sector and then to open the damaged magnets for inspection, and then another month to re-chill them to their operating temperature. read more »
