/ Otarid, Younes (CERN) ; Benoit, Mathieu (ORNL, Oak Ridge (main)) ; Buschmann, Eric (Brookhaven Natl. Lab.) ; Chen, Hucheng (Brookhaven Natl. Lab.) ; Dannheim, Dominik (CERN) ; Kamoisis, Ilias (CERN) ; Koffas, Thomas (Carleton U. (main)) ; St-Jean, Ryan (Carleton U. (main)) ; Spannagel, Simon (DESY) ; Tang, Shaochun (Brookhaven Natl. Lab.) et al.
Caribou is a versatile data acquisition (DAQ) system developed within several collaborative frameworks (CERN EP R&D;, DRD3, AIDAinnova, and Tangerine) to support laboratory and test-beam characterization of novel silicon pixel detectors. It combines a custom Control and Readout (CaR) board with a Xilinx Zynq System-on-Chip (SoC) running project-wide shared firmware and software stacks. [...]

Performance of the LHCb muon detector in Run 3
/ Albicocco, P. ; Anelli, M. ; Archilli, F. ; Atzeni, M. ; Baldini, W. ; Balla, A. ; Belin, S. ; Bondar, N. ; Brundu, D. ; Cadeddu, S. et al.
In Run 3 of the LHC, the instantaneous luminosity at the LHCb interaction point has been increased by a factor of five, from $4\times 10^{32}\rm{cm}^{-2}\rm{s}^{-1}$ to $2\times 10^{33}\rm{cm}^{-2}\rm{s}^{-1}$. Several hardware interventions, including a complete overhaul of the readout electronics, have been carried out on the muon detector. [...]

Multi-Gsps ADC radiation qualification for the LHC BPM system consolidation
/ Barros Marin, M (CERN) ; Boccardi, A (CERN) ; Can Ozdogan, S (CERN) ; Danzeca, S (CERN) ; Ferraro, R (CERN) ; Krupa, M (CERN) ; Scialdone, A (CERN)
The consolidation of the Large Hadron Collider (LHC) Beam Position Monitor (BPM) requires digitising analogue signals from more than 1000 dual-plane BPMs using radiation-tolerant analogue-to-digital converters (ADCs). To this end, two commercial off-the-shelf (COTS) quad-channel, 12-bit ADCs operating at up to 1.6 Gsps were tested. [...]

Powder Metallurgy and Heat Treatment Effects on Microstructure in a γ-TiAl Ti-4522XD Alloy
/ Ruiz-Palenzuela, B (Carlos III U., Madrid ; CERN) ; Sabirov, I (IMDEA Software Institute, Spain) ; Ruiz-Navas, E M (Carlos III U., Madrid)
This investigation focuses on the microstructural refinement of the γ-TiAl intermetallic alloy Ti-45Al-2Nb-2Mn (at.%) + 0.8 (vol.%) TiB2 (Ti4522XD) processed by powder metallurgy. The alloy powders were manufactured using the Electrode Induction-melting Gas Atomization (EIGA) process and subsequently consolidated through Hot Isostatic Pressing (HIP), resulting in a near-γ microstructure.The study further explores the effects of three distinct thermal treatments on the microstruc ture: 1) heating to 1300°C for 2 hours followed by furnace cooling (HT1), 2) heating to 1300°C for 2 hours, then water quenching and aging at 850°C for 8 hours before furnace cooling (HT2), and 3) heating to 1300°C for 2 hours, followed by water quenching and aging at 700°C for 8 hours before furnace cooling (HT3).

Manufacture and QC of the ATLAS Inner Tracker (ITk) pixel quad module flex
/ Bates, R (Glasgow U.) ; Naik, S (Glasgow U.)
/ATLAS ITK Collaboration
ITk hybrid pixel detector consists of about 10,000 planar “quad” modules formed from 4 ASICs, (developed within the RD53 collaboration) bump bonded to a single sensor.The flexible PCB attached to the sensor connects the ASICs to the system and provides module electrical environment.To guarantee a long-term reliability in the harsh HL-LHC environment, a tight quality control is mandatory.Using three bare flex and three population vendors the populated flexes are manufactured as per IPC standards,Quality Control (QC) protocols were developed to maintain quality and maximize module yield.We describe in detail the QC tests and key results..

The ATLAS Inner Tracker will operate at the HL-LHC following Long Shutdown 3, where humidity monitoring will be essential in protecting sensitive electronics. Conventional humidity sensors are unsuitable due to them being susceptible to radiation damage. [...]

A quantum-inspired classification for random mixed states
/ Sergioli, Giuseppe (U. Cagliari (main)) ; Cuccu, Carlo (U. Cagliari (main)) ; Rieger, Carla Sophie (CERN ; Tech. U., Munich (main)) ; Granda Arango, Andrés Camilo (U. Cagliari (main)) ; Behera, Bikash Kumar (U. Cagliari (main)) ; Era, Riccardo (U. Cagliari (main)) ; Giuntini, Roberto (U. Cagliari (main) ; Tech. U., Munich (main))
We present a quantum-inspired classification framework designed to identify correlation structures: product, separable, and entangled, in random mixed quantum states. Building on previous work where the Pretty-Good-Measurement (PGM) classifier demonstrated a competitive performance on pure-state ensembles, we extend this method to the more challenging domain of mixed states.

We report a high-precision mass measurement of Zn61, performed with the ISOLTRAP mass spectrometer at ISOLDE, CERN. Our result agrees with a recent measurement from the LEBIT Penning trap at FRIB and reduces the mass uncertainty by a factor of four. [...]
