GENEVA - Fixing the world's largest atom smasher will cost at least CHF 25 million and may take until early summer, its operator said Monday.

An electrical failure shut down the Large Hadron Collider on 19 September, nine days after the USD 10 billion (CHF 12 billion) machine started up with great fanfare.

The European Organisation for Nuclear Research recently said that the repairs would be completed by May or early June. Spokesman James Gillies said the organisation know as CERN is now estimating the restart will be at the end of June or later.

"If we can do it sooner, all well and good. But I think we can do it realistically (in) early summer," he said.

The organisation has blamed the shutdown on the failure of a single, badly soldered electrical connection.

The atom smasher operates at temperatures colder than outer space to get maximum efficiency and experts needed to gradually warm the damaged section to better assess it, he said.

"Now the sector is warm so they are able to go in and physically look at each of the interconnections," Gillies told The Associated Press.

The cost of the work will fall within the organisation's existing budget, Gillies said.

The massive machine on the Swiss-French border was built to smash protons from hydrogen atoms together at high energy and record what particles are produced by the collisions, giving scientists a better idea of the makeup of the smallest components of matter.

That will show on a tiny scale what happened one-trillionth of a second after the so-called Big Bang, which many scientists theorise was the massive explosion that formed the universe. The theory holds that the universe was rapidly cooling at that stage and matter was changing rapidly.

Scientists have taken the setback in stride, saying that particle colliders always have such problems in the startup phase.
