D0 triggering and data acquisition
- Brookhaven National Laboratory, Bldg 150C, Upton, New York, 11973 (United States)
The trigger for D0 is a multi-tier system. Within the 3.5 [mu]sec bunch crossing interval, custom electronics select interesting event candidates based on electromagnetic and hadronic energy deposits in the calorimeter and on indications of tracks in the muon system. Subsequent hardware decisions use refined calculations of electron and muon characteristics. The highest level trigger occurs in one element of a farm of microprocessors, where fully developed algorithms for electrons, muons, jets, or missing [ital E][sub [ital t]] are executed. This highest level trigger also provides the assembly of the event into its final data structure. Performance of this trigger and data acquisition system in collider operation is described.
