The PreProcessors for the ATLAS tile calorimeter phase II upgrade
2015
The
Large Hadron Colliderhas envisaged a series of upgrades towards a High Luminosity LHC delivering five times the LHC nominal instantaneous luminosity. The ATLAS Phase II Upgrade will accommodate the detector and data acquisition system for the HL-LHC. In particular, the Tile Hadronic Calorimeter will completely replace front-end and back-end electronics using a new read-out architecture. The digitized detector data will be transferred for every
beam crossingto the
PreProcessorslocated in off-detector counting rooms with a total data bandwidth of roughly 80 Tbps. The TilePPr implements larger pipelines memories and must provide pre-processed digital trigger information to Level 0/1 trigger systems. The TilePPr system represents the link between the front-end electronics and the overall ATLAS data acquisition system. It also implements the interface between the Detector Control System and the front-end electronics which is used to control and monitor the high voltage distribution system. The TilePPr is responsible of transmitting the commands to configure, control and monitor the front-end electronics.
