LHC progress Report from CERN's Director General:
This weekend we’ve seen further important progress with beam commissioning in the LHC at 450 GeV. On Friday evening, 4 December, beam circulated with more than one proton bunch for the first time. This was another significant step towards running at useful beam intensities.
Then in the early hours of Sunday, the operators succeeded in circulating four bunches in each of the LHC’s two beams and announced stable beams for the experiments. On Sunday evening there was further stable running with higher-intensity bunches. All six LHC experiments have observed collisions and collected useful quantities of data. They were able immediately to begin checking the operation of their detectors, with excellent results that augur well for the future.
