FMUON 1995 trigger page


The FMUON trigger consists of 3 filters:

 FMU Elastic , select elastic events with muons of any momentum
               [ but greater than the energy loss in FCAL, about 2.5 GeV ]

 FMU Any Et ,  select events with high momentum muons
               [ p(mu) > 8-10 GeV/c ]

 FMU High Et , select events with high transverse energy and 
               high momentum muons
               [ Et > 5 GeV ; p(mu) > 8-10 GeV/c ]


Trigger rates during '95 data taking were approximately the following:
