CERN Shutdown Until Thanksgiving

Not good news. Problems at CERN mean the LHC won't restart until mid-November at the earliest. The good news is that those culturally deficient Europeans don't celebrate Thanksgiving so they'll get a few shots in at finding the elusive Higgs Boson. Uh-oh, don't they shut the thingy down in the winter to save electricity?

"The foreseen shutdown work on the LHC is proceeding well, including the powering tests with the new quench protection system. However, during the past week vacuum leaks have been found in two "cold" sectors of the LHC...

Unfortunately, the repair necessitates a partial warm-up of both sectors. This involves the end sub-sector being warmed to room temperature, while the adjacent sub-sector "floats" in temperature and the remainder of the sector is kept at 80 K. As the leak is from the helium circuit to the insulating vacuum, the repair work will have no impact on the vacuum in the beam pipe. However the intervention will have an impact on the schedule for the restart. It is now foreseen that the LHC will be closed and ready for beam injection by mid-November."
