Description
Stable, precise spatial alignment and PID calibration are necessary to achieve optimal detector performances.
During Run2, LHCb will have a new real-time detector alignment and calibration to reach equivalent performances in the online and offline reconstruction.
This offers the opportunity to optimise the event selection by applying stronger constraints as well as hadronic particle identification at the trigger level.
The required computing time constraints are met thanks to a new dedicated framework using the multi-core farm infrastructure for the trigger.
The motivation for a real-time alignment and calibration of the LHCb detector is discussed from the operative and physics performance point of view.
Specific challenges of this configuration are discussed, as well as the designed framework and its performance.
