• LHC Commissioning with beam is now planned for
  May 2008. It will be performed in well-defined
  stages
• Stage A Initial commissioning with a single
  bunch moving towards 43 on 43 (moving to 156 on
  156) with moderate intensities. First collisions
  un-squeezed followed by partial squeeze. (LHC
  initial commissioning - draft project note)
• Stage B Move to 75 ns. bunch spacing with the
  aim of moving to intensities around 3 - 4 1010
  particles per bunch
• Stage C Move to 25 ns. with the aim of moving
  to intensities around 3 - 4 1010 particles per
  bunch. Would need to be followed by long shutdown
  for  installation of phase 2 collimation and
  additional beam dump dilutors.
• Stage D Nominal 25 ns running pushing towards
  design intensity and full squeeze.
