Performance of the ATLAS muon triggers in Run 2
(IOP Publishing, 2020-09)
The performance of the ATLAS muon trigger system is evaluated with proton-proton (pp) and heavy-ion (HI) collision data collected in Run 2 during 2015–2018 at the Large Hadron Collider. It is primarily evaluated using ...
Performance of the upgraded PreProcessor of the ATLAS Level-1 Calorimeter Trigger
(IOP Publishing, 2020-11)
The PreProcessor of the ATLAS Level-1 Calorimeter Trigger prepares the analogue trigger signals sent from the ATLAS calorimeters by digitising, synchronising, and calibrating them to reconstruct transverse energy deposits, ...
Operation of the ATLAS trigger system in Run 2
(IOP Publishing, 2020-10)
The ATLAS experiment at the Large Hadron Collider employs a two-level trigger system to record data at an average rate of 1 kHz from physics collisions, starting from an initial bunch crossing rate of 40 MHz. During the ...
