/ Akiba, Kazu (Nikhef, Amsterdam) ; van Beuzekom, Martin (Nikhef, Amsterdam) ; van Beveren, Vincent (Nikhef, Amsterdam) ; Byczynski, Wiktor (CERN ; Cracow Tech. U.) ; Coco, Victor (CERN) ; Collins, Paula (CERN) ; Dall'Occo, Elena (Dortmund U.) ; Dumps, Raphael (CERN) ; Evans, Tim (Manchester U.) ; Geertsema, Robbert (Nikhef, Amsterdam) et al.
The design of a detector system comprised of four silicon sensors bump-bonded to Timepix4 ASICs is described together with its data acquisition system, operational infrastructure, and dedicated software. The spatial and temporal performance of the system are assessed with a 180 GeV/c mixed hadron beam at the CERN SPS and reported in detail. [...]

Simulation and Optimization Studies of the LHCb Beetle Readout ASIC and Machine Learning Approach for Pulse Shape Reconstruction
/ Kopciewicz, Pawel (AGH University of Science and Technology (PL)) ; Akiba, Kazu (Nikhef National institute for subatomic physics (NL)) ; Szumlak, Tomasz (AGH University of Science and Technology (PL)) ; Sitko, Sebastian Piotr ; Barter, William (Imperial College (GB)) ; Buytaert, Jan (CERN) ; Eklund, Lars (Uppsala University (SE)) ; Hennessy, Karol (University of Liverpool (GB)) ; Koppenburg, Patrick (Nikhef National institute for subatomic physics (NL)) ; Latham, Thomas Edward (University of Warwick (GB)) et al.
The optimization of the Beetle readout ASIC and the performance of the software for the signal processing based on machine learning methods are presented. The Beetle readout chip was developed for the LHCb (Large Hadron Collider beauty) tracking detectors and was used in the VELO (Vertex Locator) during Run 1 and 2 of LHC data taking. [...]

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. [...]
