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
