Abstract (en)

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   long shutdown of the LHC from 2013 to 2014, the central components   of the PreProcessor, the Multichip Modules, were replaced by   upgraded versions that feature modern ADC and FPGA technology to   ensure optimal performance in the high pile-up environment of LHC   Run 2.  This paper describes the features of the new Multichip   Modules along with the improvements to the signal processing achieved.
