Switzerland – CERN (European Council for Nuclear Research) has announced that the restart of the LHC (Large Hadron Collider), the largest subatomic particle collider, is now scheduled for this fall.

Researchers believe they have found a way to prevent a repeat of the incident which ruined “the most expensive experiment of all our History”, at the end of 9 days of operation.

Small reminder of the incident: this machine is the most complex of the world, includes an underground ring 27 km in diameter. It overheated in September 2008, due to a defect in a superconducting wire connecting two magnets of cooling. It had to interrupt its operation. However, there are 10,000 such components to check with the LHC.

It has been several times that the CERN pushes back the restarting of the LHC. This time, the spokesman for Cern, Steve Myers, said: “We carried out many tests and that got many useful informations to us. We are now trustful and think that we can start again this year. All that we make will prepare the machine for one long life of operation thereafter.”

Repairs and modifications should practically cost 40 million euros.
