Considerations for the VELO detector at the LHCb Upgrade II / Akiba, Kazu (Nikhef National institute for subatomic physics (NL)) ; Alexander, Michael Thomas (University of Glasgow (GB)) ; Back, John James (University of Warwick (GB)) ; Bates, Richard (University of Glasgow (GB)) ; Bertella, Claudia (University of Manchester (GB)) ; Van Beuzekom, Martin (Nikhef National institute for subatomic physics (NL)) ; Seman Bobulska, Dana (University of Glasgow (GB)) ; Boente Garcia, Oscar (Universidade de Santiago de Compostela (ES)) ; Bogdanova, Galina (M.V. Lomonosov Moscow State University (RU)) ; Borghi, Silvia (University of Manchester (GB)) et al.
The LHCb experiment is planning to operate with a 7.5-fold increase in instantaneous luminosity for LHC Runs 5 and 6. The performance of the Vertex Locator detector is crucial in the event reconstruction at the increased pile-up, providing real-time information to be used in the trigger. [...]

The VELO optical and power board / Eklund, Lars (Uppsala University (SE)) ; Van Beuzekom, Martin (Nikhef National institute for subatomic physics (NL)) ; Buytaert, Jan (CERN) ; Dean, Cameron Thomas (Los Alamos National Laboratory (US)) ; De Bruyn, Kristof Antoon M (University of Groningen (NL)) ; Dumps, Raphael (CERN) ; Fernandez Prieto, Antonio (Universidade de Santiago de Compostela (ES)) ; Hennessy, Karol (University of Liverpool (GB)) ; Leflat, Alexander (M.V. Lomonosov Moscow State University (RU)) ; Lemos Cid, Edgar (Universidade de Santiago de Compostela (ES)) et al.
The optical and power boards (OPB) are part of the on-detector electronics system for the LHCb Vertex Detector (VELO) and they are used in LHCb upgrade 1 which is installed in the second long LHC shutdown period. The OPBs are assembled printed circuit boards (PCBs) that are located immediately outside of the VELO detector vacuum tank, in custom made mechanical crates. [...]

Microchannel Cooling for the LHCb VELO Upgrade I / Collins, Paula (CERN) ; De Aguiar Francisco, Oscar Augusto (University of Manchester (GB)) ; Byczynski, Wiktor (Tadeusz Kosciuszko Cracow University of technology (PL)) ; Akiba, Kazu (Nikhef National institute for subatomic physics (NL)) ; Bertella, Claudia (University of Manchester (GB)) ; Bitadze, Alexander (University of Manchester (GB)) ; Buytaert, Jan (CERN) ; De Capua, Stefano (University of Manchester (GB)) ; Callegari, Riccardo (CERN) ; Catinaccio, Andrea (CERN) et al.
The LHCb VELO Upgrade I, currently being installed for the 2022 start of LHC Run 3, uses silicon microchannel coolers with internally circulating bi-phase \cotwo for thermal control of hybrid pixel modules operating in vacuum. This is the largest scale application of this technology to date. [...]

LHCb RICH: Potential physics performance / Calvi, Marta (Universita & INFN, Milano-Bicocca (IT)) ; Cardinale, Roberta (INFN e Universita Genova (IT)) ; Cavallero, Giovanni (CERN) ; Fazzini, Davide (Universita & INFN, Milano-Bicocca (IT)) ; Martinelli, Maurizio (CERN)
In Upgrade phases the PID performance are expected to be reduced by the high detector occupancy and large event multiplicity. The use of fast timing information can be one of the key element to restore and improve the performance of the current RICH detectors in these conditions. [...]

LHCb Computing Resources: preliminary 2023 requests / Bozzi, Concezio (Universita e INFN, Ferrara (IT))
This document presents a preliminary assessment of the offline computing resources needed by LHCb in 2023. The computing requests are based on the Computing Model Technical Design Report for the LHCb Upgrade, adjusted to the currently known LHC running schedule and the expected activities to be performed by the LHCb experiment..

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..
