Performance of the upgraded PreProcessor of the ATLAS Level-1 Calorimeter Trigger

G. Aad, B. Abbott, D. C. Abbott, A. Abed Abud et autres

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, which are then used in further processing to identify event features.During the first …
