The ATLAS trigger system is responsible for reducing the event rate, from the design bunch-crossing rate of 40 MHz, to an average recording rate of 200 Hz, by selecting signal-like events out of the extremely large background. The ATLAS trigger is designed in three levels. The first-level (L1) is implemented in custom-built electronics, the two levels of the high level trigger (HLT) are...

The ALICE trigger system in the experimental cavern processes information from triggering detectors at 3 hardware levels in p-p and Pb-Pb collisions. The performance of the system exceeds the specification and many automatic functions have been developed to facilitate work in the control room. The hardware is permanently monitored, and around 1200 counters, with considerable built-in...
