Article: Hadron Collider`s Transformer Breaks GENEVA, Switzerland (AP) -- A 30-ton transformer that cools the world's largest particle collider malfunctioned, forcing physicists to stop using the atom smasher just a day after launching it to great fanfare, the European Organization for Nuclear Research said Thursday.
The faulty transformer has been replaced and the ring in the 17-mile circular tunnel under the Swiss-French border has been cooled back down to near absolute zero -- or minus 459.67 degrees Fahrenheit -- the most efficient operating temperature, said a statement by CERN, as the organization is known.
