Smelly Jeffrey writes "The BBC is reporting that the LHC has had all eight of its sectors cooled to 1.9 Kelvin. Their tagline is that it is now 'colder than deep space,' referring to the CMB. LHC engineers have spent nearly $40,000,000 USD on a new system to prevent the 'quench' condition that caused the LHC to be down for warming, repairs, and re-cooling over the last year. The LHC is now cold enough to begin colliding particles in search of the Higgs Boson. High power collisions won't be started until late December, or perhaps early January. However, a low-power beam through parts of the collider could be tested as early as next week!"
