CERN says atom-smasher down for two months


The world's largest particle collider will be down for two months as a section will have to be repaired because of a fault, a spokesman for the European Organisation for Nuclear Research (CERN) said.

James Gillies told AFP: "There has been an incident in a test. One section of the machine will have to be repaired."

The Large Hadron Collider was started on September 10, but it had to be shut down on Thursday last week because of a fault in the cooling system.

It was turned back on again on Friday, but the latest incident has once again forced operations to halt.

The LHC took nearly 20 years to complete and at six billion Swiss francs (3.76 billion euros, 5.46 billion dollars) is one of the costliest and most complex scientific experiments ever attempted.

It aims to resolve some of the greatest questions surrounding fundamental matter, such as how particles acquire mass and how they were forged in the "Big Bang" that created the universe some 13.7 billion years ago.
