LHC-B Muon Trigger

The LHC-B muon detector configuration and the components necessary forthe LHC-B Level 0 high $p_t$ muon trigger are discussed. The Level 0trigger algorithm necessary to achieve the desired suppression of triggers due to minimum bias events while maintaining good efficiency for semimuononicB decays is described. Results of various studies of this trigger, includingeffects of variation of minimum and maximum angular apertures, studies of the effect of the size of non-major components of the LHCB magnetic field, andstudies of showering in the muon shield, are presented together with anevaluation of the muon pad chamber granularity required for achieving the LHC-B Level 0 trigger objectives.
