When the did LHC(Large Hadron Collider) got into action????

Very eager to know....?, Here, i have some information s to u about it...

The Large Hadron Collider will come back online in late summer 2009 at the earliest, and not in June as previously expected.

The LHC was shut down in September 19, nine days after it was first fully powered up(september 10), following a helium leak caused by an electrical fault. The world's most powerful particle accelerator is designed to smash beams of protons into each other, test fundamental physics theories, and help understand the nature of matter.

The machine is located at the European Center for Nuclear Research (CERN), where it straddles the Swiss-French border.

CERN director Robert Aymar said in October that the LHC would come back online at the beginning of April 2009, following CERN's annual maintenance period. Earlier this month, that date was revised to June 2009.

However, the plan now is to restart the experiment in late summer next year.....

I think, this will be sufficient....

10th of September is the first time they sent proton beams around the LHC, however it was turned off on the 19th and will not be turned on again until summer 2009, this was due to a fault between two superconducting bending magnets
