LHC machine status and schedule (最新情報)
- The current planning of the LHC is such that the machine is expected to be cold by mid-June, when we(ATLAS) must be closed, and first injections could start very soon after (end June) - CERN Management will give ATLAS a warning signal 2 months before we start closing, currently expected by mid-April when the progress on the machine will be known from the cool down status of further sectors - Experience from power tests in Sector 4-5 showed that several magnets need training, starting somewhere above 5 TeV equivalent - The first physics run (typically 2 months) in 2008 will be at 10 TeV (or slightly above), the energy will be defined in April when experience from Sector 5-6 will also be available Similar statements were just made during this Council Week, in addition it was said that 10 TeV collisions could be reached sometime in August
