Description
The ATLAS Level-1 Central Trigger Processor (CTP) combines information
from calorimeter and muon trigger processors and makes the final Level-1
Accept (L1A) decision on the basis of lists of selection criteria (trigger
menus). In addition to the event-selection decision, the CTP also provides
trigger summary information to the data acquisition system and the Level-2
trigger. It further provides accumulated and bunch-by-bunch scaler data
for monitoring of the trigger, detector and beam conditions.
The CTP will be presented and results will be shown from tests with the
calorimeter and muon trigger processors connected to detectors in a
particle beam, as well as from stand-alone full-system tests in the
laboratory which were used to validate the CTP.
