Well, that didn't take long: the folks at CERN already broke their new toy. Per Daily Tech, the repairs on the transformer that blew have revealed that the coolant for one of the superconducting magnets has leaked into the tunnel, and the process of warming the magnet back up, making the repairs, and cooling everything back down would take some two month. As the LHC shuts down every November to avoid the expense of winter-season electricity, there will be no further testing of the collider until next spring. So much for all of that QA testing they did in August.
That's why we can't have nice things!
