Themis Bowcock - MTR
IntroductionWhy?
Consolidate and review production STOP before we go too far Produce a revised baseline procedures Larger statistics from PRR
Identify new problems (fix!) Public record Refereed (Tim Jones)
Input of experience from other experiments

Introduction:Terms of reference
Review documentation checklists, and idiot guides
Review data to identify problems Compile list of issues that need to be
addressed Identify priority items that must be
addressed before production restarted Produce short written report to the
Technical Board of LHCb

Geometry (42 modules R&Phi) R sensors must be positioned within 20 um (gauss
sigma) in X and Y of the nominal position relative to the base.
R sensors must be positioned within 100 um (gauss sigma) in Z of the nominal position relative to the base.
Phi sensors must fit within tolerances given by RF foil. The positioning has no further requirements, but the
actual position must be known to an accuracy of about 10 um relative to the R sensor.
Addition of constraint system See metrology discussion
