The eight sectors have been cooled individually over time. As three of the sectors were cooled to nominal operating temperatures, the magnets which guide and focus the beams of protons were powered up, said the bulletin.
At present, the three sectors have magnets powered at 2kA. Over the coming weeks, magnets in all eight sectors in the 27km LHC ring will gradually have current put through them, up to 6kA. This is the amount of energy needed to guide beams with a nominal energy of 3.5 TeV, or half the power envisaged for the LHC experiment, said the Cern bulletin.
Cern told ZDNet UK at the beginning of October that the LHC would probably be colliding beams by mid-November.
