James Gilles, head of communications for CERN stated today thatthe LHC should be back online by mid November, and that thing were going very well. Though there is no scheduled date for a full power up the first stages will begin in the next two weeks when scientists will inject a beam of protons into the LHC and guide them around the first sector.

Six of the eight sectors have now been cooled to – 271° C or -455 ° F and the magnets which guide the beams are being are now being powered up.

Last year an explosion caused by faulty welding in a copper busbar cause the LHC to be shut down only nine days after its initial powerup. Reportedly the new quench detection system is much better than last year’s. The quench detection system allows the resistance of all copper splices to be measured while allowing the energy to be extracted from the magnets. Last years explosion halted the normal operation of a quench resulting in the inability to drain or dump the energy in the magnets.
