Why The Large Hadron Collider Is Already On The Fritz

From Time Magazine - Science:

Anyone who has struggled to change a fuse in their home should pity the scientists at the CERN laboratory in Geneva. Last Friday, just nine days after celebrating the successful test run of the largest particle accelerator ever constructed, a tiny electrical connection between two magnets overheated and caused a minor meltdown.

The Large Hadron Collider (LHC) broke.

Although a final evaluation is yet to be completed, scientists believe the fault caused the machine to lose the near absolute-zero temperature it must maintain to operate. For now, however, repair work can't begin because the machine is still too cold; it will take about a month to warm up the area to a temperature at which replacement parts can be inserted. It will take another month to cool it back down, and given that CERN has pledged not to run its giant machine — which requires as much power as the entire city of Geneva — during winter months when Europe's energy needs are highest, Friday's breakdown could delay the actual smashing of atoms until early next year.
