Briefs: CERN: LHC relaunch

CERN's Large Hadron Collider (LHC) will initially run at an energy of 3.5 TeV per beam when it starts up in November this year. All tests on the machine's high-current electrical connections have now been completed and demonstrate that no further repairs are necessary for safe running. Following the incident of September 19, 2008 that brought the LHC to a standstill, testing has focused on the 10 000 high-current superconducting electrical connections like the one that led to the fault. At the end of 2010, the LHC will be run with lead ions for the first time. After that, the LHC will shut down and work will begin on moving the machine towards 7 TeV per beam.
