Scientist say it will cost more than $20 million to repair Europe's Large Hadron Collider.

The European Organization for Nuclear Research said the repairs could take until at least next summer to complete, The Daily Telegraph reported Friday.

The machine, designed to smash protons together at huge speeds, took nearly 20 years to complete at a cost of $6.4 billion, was shut down in September because of a badly soldered electrical connection in one of its super-cooled magnet sections. Fifty-three of the 57 magnets in the collider's tunnel beneath the Swiss-French border must be removed and reinstalled during the repair process, the report said.
