Design and Commissioning of the First 32-Tbit/s Event-Builder / Pisani, Flavio (CERN) ; Colombo, Tommaso (CERN) ; Durante, Paolo (CERN) ; Frank, Markus (CERN) ; Gaspar, Clara (CERN) ; Granado Cardoso, Luis (CERN) ; Neufeld, Niko (CERN) ; Perro, Alberto (CERN ; INFN, Turin ; Turin U.)
The large hadron collider beauty (LHCb) experiment is a forward spectrometer, designed to study beauty and charm quarks physics at the large hadron collider (LHC). To exploit of the higher luminosity that will be delivered during Run3, the full experiment needed a substantial upgrade, from the detector to the data acquisition (DAQ) and high level trigger (HLT). In this article, we will focus on the new DAQ system for the LHCb experiment that represents a substantial paradigm shift compared to the previous one, and to similar systems used by similar experiments in the past and present times.

The LHCb HLT2 Storage System: A 40-GB/s System Made of Commercial Off-the-Shelf Components and Open-Source Software / Cifra, Pierfrancesco (Nikhef, Amsterdam) ; Sborzacchi, Francesco (Frascati) ; Neufeld, Niko (CERN) ; Hemmer, Frederic (CERN)
The Large Hadron Collider beauty (LHCb) experiment is designed to study differences between particles and antiparticles as well as very rare decays in the charm and beauty sector of the standard model at the Large Hadron Collider (LHC). With the major upgrade done in view of Run 3, the detector will read out all events at the full LHC bunch-crossing frequency of 40 MHz. [...]

The LHCb DAQ Upgrade for LHC Run3 / Colombo, Tommaso (CERN) ; Durante, Paolo (CERN) ; Galli, Domenico (INFN, Bologna) ; Marconi, Umberto (INFN, Bologna) ; Neufeld, Niko (CERN) ; Pisani, Flavio (CERN ; INFN, Bologna ; Bologna U.) ; Schwemmer, Rainer (CERN) ; Valat, Sébastien (CERN) ; Voneki, Balazs (CERN)
In order to optimize the physics reach in the large hadron collider (LHC) Run3, foreseen in the years 2021 and beyond, the LHC beauty experiment collaboration has decided to re-design its detector and the data acquisition system (DAQ). The new detector will operate at the LHC bunch-crossing frequency of 40 MHz without hardware trigger. [...]
