Strategy for 2008 2009 2008 A No beam Beam 2009 B C No beam Beam
Stage A physics running for ALICE and LHCb • 43 (44) equidistant bunches • Need to do something for LHCb • Previously thought to displace bunches in one beam (asym) • Can do better (symmetrically displace bunches in both beams) • Allows to adjust luminosity sharing between 2 and 8 while keeping maximum number of collisions in 1 and 5
TBSO • Parameter list • Circuits and currents • What is needed, what is not • What do we do about magnets at zero field • Implications • Experiment magnets will be at 7TeV field • Collimators • Getting ready for 2009 • Training to 7TeV • Circuits not commissioned in 2008 • 75ns and 25ns operation • ions
