Quantum error mitigation for Fourier moment computation
/ Kiss, Oriel (CERN ; U. Trento (main)) ; Grossi, Michele (CERN) ; Roggero, Alessandro (U. Trento (main) ; ECT, Trento ; FBK, CIT, Trento ; INFN, Trento)
Hamiltonian moments in Fourier space - expectation values of the unitary evolution operator under a Hamiltonian at different times - provide a convenient framework to understand quantum systems. They offer insights into the energy distribution, higher-order dynamics, response functions, correlation information and physical properties. [...]

Failure analysis and lessons learned on crate and power supply equipment
/ Bobillier, V (CERN) ; Edvardsen, J (CERN) ; Mico, S (CERN) ; Pinzoni, C (CERN) ; Smaniotto, B (CERN)
For nearly 20 years, the Power Supply and Crate Service at CERN has been responsible forthe maintenance tracking of power supplies and crates used by the CERN experiments. With thisexperience, and with the imminent introduction of a new generation of power supplies for theHL-LHC, the timing is ideal to conduct a statistical analysis to draw lessons from the past andmake recommendations for the future.

SOCRATES: a radiation-tolerant SoC generator framework
/ Andorno, Marco (CERN) ; Caratelli, Alessandro (CERN) ; Ceresa, Davide (CERN) ; Denkinger, Benoît (CERN) ; Kloukinas, Kostas (CERN) ; Nookala, Anvesh (CERN) ; Pejašinović, Risto (CERN)
As front-end ASIC complexity in HEP experiments grows, there is a shift towards more modular, programmable, and cost-effective designs. This work introduces the SOCRATES platform, a radiation-tolerant SoC generator toolset, based on SoCMake, a hardware/software build system that automates SoC assembly and verification. [...]

Optimisation and validation of power delivery networks for multi-gigabit data links
/ Martina, F (CERN ; INFN, Lecce) ; Biereigel, S (CERN) ; Baron, S (CERN) ; Baszczyk, M (CERN) ; Klekotko, A (CERN ; Leuven U.) ; Kulis, S (CERN) ; Moreira, P (CERN) ; Soos, C (CERN)
The performance of ASICs for high-bandwidth communications is heavily influenced by the interconnection with the hosting module and paired devices, including the bonding scheme and the PCB layout. The recent validation campaign of the 25.6 Gbps DART28 transmitter has highlighted that a coordinated simulation and design of the power delivery network is required to achieve satisfactory performance.

Evaluation of efficiency, radiation hardness, and timing performance of the Analogue Pixel Test Structure for ALICE ITS3
/ Liu, J (Liverpool U.)
/ALICE Collaboration
A replacement of the three innermost layers of the new ALICE Inner Tracking System (ITS2), referred to as ITS3, is planned for the LHC Long Shutdown 3 (2026–2028) to further enhance tracking precision and efficiency. The ITS3 is designed as a cylindrically bent silicon vertex detector, utilizing stitched, wafer-scale sensors developed with the Tower Partners Semiconductor Co. [...]

Power distribution over the wafer-scale monolithic pixel detector — MOSAIX for ALICE ITS3
/ Aglieri Rinella, G (CERN) ; Bugiel, S (CERN) ; Dobrijevic, D (CERN) ; Lemoine, C (CERN) ; Snoeys, W (CERN) ; Vicente Leitao, P (CERN)
/ALICE Collaboration
For the LS3 ALICE ITS3 upgrade the detector material budget reduction has been pushed to the limit by proposing a system composed almost exclusively of silicon wafer thinned down to 50μm. This improves performance, but adds complexity to the ASIC design. [...]

First results of an evaluation of $^{100}$Gb/s Ethernet as a future HEP readout link

This work presents first results from a feasibility study to qualify commercial 100 Gb/s Ethernet as a readout link for future high-energy physics detectors. The motivation for this work is to examine the possibility of reading out future detector front-ends directly via commercial, high bandwidth, cost-optimized data centers, without the need of the intermediate custom-link/hardware layer used for this purpose thus far.
