Magnet Polarity We can swap the magnet polarity ➜ Important for systematic studies of CP effects So far have taken 10% data with field Up. Will catch up soon 3.5 TeV, Field Down 3.5 TeV, Field Up Primary vertex in Beam Gas events for Beam1 and Beam2 z coverage due to velo acceptance Crossing angle due to B field Beam profiles used to determine luminous region ➜ Luminosity Patrick Koppenburg LHCb Status Report 101 st LHCC — 5 May 2010 [6/39]
