CERN Says LHC is Almost Cool

Good news on the long trek to bring the LHC online after an extended downtime to replace numerous magnets. The LHC is almost cooled down again!

The LHC must run at a chilly -271??C at all times and it takes quite a while to get all 27 kilometers of beamline down to that temperature. Scientists at the LHC are still waiting on two of eight sectors to be fully chilled, though they're already in the process of cooling as I write this. And when they're done... the magnets can be turned on again. That's really the turning point to figure out if the repairs over the last six months have been successful.
