The main purpose of the Global Muon Trigger logic is to combine the output of the different trigger systems RPC and DTBX for a certain trigger decision and to improve the efficiencies of the individual triggers.
From table 3, 4, 5 and 6 we can see, that the chosen logic of the Global Muon Trigger reduces the percentage of undetected muons in the single and multi muon cases drastically. Consequently the trigger efficiency is enhanced compared to the RPC and DTBX triggers alone. On the other hand a much higher proportion of additional muons compared to the RPC and DTBX triggers is produced, because some muons were not recognized to be identical.
Moreover if only a single muon is found by the Global Trigger algorithm in a generated single muon event, then in over 93% of the cases both RPC and DTBX have found it.
The assigned
,
, and
values from the Global Muon Trigger,
compared to the corresponding values from RPC and DTBX are shown in
fig. 4.
In fig. 15 we see the smoothing effect in
of the
Global Muon Trigger algorithm quite clearly in comparison to the respective
observations in fig. 2. Clearly
and
inefficiencies are overcome by the algorithm.
Therefore our first attempt to implement a Global Muon Trigger is promising.
