Tracking Definitions and Conventions for Run 3 and Beyond / Li, Peilian (Ruprecht Karls Universitaet Heidelberg (DE)) ; Rodrigues, Eduardo (University of Liverpool (GB)) ; Stahl, Sascha (CERN)
This note describes definitions, conventions and rules to measure the performance of detecting charged particles in the LHCb tracking detectors and, subsequently, reconstructing them with the track reconstruction software. In addition, the distributions of particles which can be reconstructed by the tracking detectors are studied using Monte Carlo simulation for Run 3..

LHCb Computing Resources: 2022 requests / Bozzi, Concezio (Universita e INFN, Ferrara (IT))
This document presents an assessment of the offline computing resources needed by LHCb in 2022, where data will be taken with the upgraded LHCb detector. The computing requests are based on the Computing Model Technical Design Report for the LHCb Upgrade, with adjustments due to the change of the LHC running schedule and the expected activities to be performed by the LHCb experiment

Characterisation of a new type of noise observed in Hamamatsu R11265 Multi-Anode Photomultipliers / Cavallero, Giovanni (CERN)
A new type of signal-induced-noise pulses is observed in Hamamatsu R11265 Multi-Anode Photomultipliers, manifesting up to several microseconds after the single-electron-response signal and being localised in specific anodes. The average number of these pulses is different between devices, and it presents a significant dependence on the applied high-voltage. [...]

Probe for LUminosity MEasurement in LHCb / Barsuk, Sergey (Université Paris-Saclay (FR)) ; Roy, Laurent (CERN) ; Rochet, Jacky (CERN) ; Panshin, Gennady (National Research Tomsk Polytechnic University (RU)) ; Sanders, Freek (Nikhef National institute for subatomic physics (NL)) ; Balagura, Vladislav (Centre National de la Recherche Scientifique (FR)) ; Fleuret, Frederic (Centre National de la Recherche Scientifique (FR)) ; Maurice, Emilie Amandine (Centre National de la Recherche Scientifique (FR)) ; Beigbeder-Beau, Christophe (Université Paris-Saclay (FR)) ; Burmistrov, Leonid (Université Paris-Saclay (FR)) et al.
A new detector capable of measuring the luminosity and beam conditions of the Large Hadron Collider (LHC) is proposed at the interaction point of the LHCb experiment. It will enable real time monitoring of beam parameters, which is of paramount importance in order to safely operate the LHC and its experiments in the beam conditions foreseen for Run 3, starting in 2021, and beyond, towards the High-Luminosity (HL) phase.

Implementation of large-scale FPGA reconfiguration with CvP in the control system of the LHCb Experiment at CERN / Achour, Mohamed (CERN)
This report present the work done during the internship period held in the LHCb group at CERN. LHCb or Large Hadron Collider beauty, is an experiment among many others at CERN, using a large number of FPGA boards for data processing and data acquisition, making a full chip reconfiguration for all those boards may consume a lot of time and effort, so the partial reconfiguration mechanism is the privileged solution to deal with that issue, PR feature is used to dynamically reconfigure some parts in the design during FPGA runtime mode, without resetting or power cycling the whole system. [...]

The Spaghetti type Calorimeter (SPACAL) with fibers parallel to the beam direction is considered as an option for the inner part of the future LHCb Electromagnetic Calorimeter (ECAL) for the Upgrade Phase 2 [1]. In this work a simulation study of the time measurement precision has been performed for the electron and photon beams with energies of 1, 2, 4, 5 and 10 GeV..
