Methodology for Feedback Loop Detection and Automatic Voter Placement in TMR Netlists / Jonckers, Laël (Leuven U.) ; Jonckers, Naïn (Leuven U.) ; Biereigel, Stefan (Leuven U. ; CERN) ; Prinzie, Jeffrey (Leuven U.)
In this paper, we present an algorithm for detecting feedback loops in sequential digital circuits as well as an algorithm for optimally inserting majority voters on essential circuit nodes which are vulnerable to Single Event Upsets (SEUs). [...]

Expanding the CERN ion injector chain capabilities: new beam dynamics simulation tools for future ion species / Waagaard, Elias Walter (EPFL - Ecole Polytechnique Federale Lausanne (CH)) ; Alemany Fernandez, Reyes (CERN) ; Bartosik, Hannes (CERN) ; Bruce, Roderik (CERN) ; Soubelet, Felix (CERN)
The present ion physics program in the CERN accelerator complex is mainly based on lead (208Pb82+) ion beams. Lighter ions have been considered both by the ALICE3 detector upgrade proposal at the Large Hadron Collider (LHC) -- as a potential way to achieve higher integrated nucleon-nucleon luminosity compared to the present Pb beams -- and also by the Super Proton Synchrotron (SPS) fixed-target experiment NA61/SHINE. [...]

Serial Powering Scheme and Performance Analysis for Innermost Layer (L0) for ATLAS ITk modules / Samy, Md Arif Abdulla (Universita degli Studi di Trento and INFN (IT)) ; Pianori, Elisabetta (Lawrence Berkeley National Lab. (US)) ; Heim, Timon (Lawrence Berkeley National Lab. (US)) ; Thompson, Emily Anne (Lawrence Berkeley National Lab. (US)) ; Dalla Betta, Gian-Franco /ATLAS Collaboration
After ten years of massive success, the Large Hadron Collider (LHC) at CERN is going for an upgrade to the next phase, the High Luminosity Large Hadron Collider (HL-LHC) which is planned to start its operation in 2029. This is expected to have a fine boost to its performance, with an instantaneous luminosity of 5.0×1034 cm-2s -1 (ultimate value 7.5×1034 cm-2s -1) with 200 average interactions per bunch crossing which will increase the fluences up to more than 1016 neq/cm2, resulting in high radiation damage in ATLAS detector [1].

Full-Bridge Modular Multilevel Converter for the Four-Quadrant Supply of High Power Magnets in Particle Accelerators / Colmenero, Manuel (CERN) ; Vidal-Albalate, Ricardo (Jaume I U., Castellon) ; Blanquez, Francisco R (CERN) ; Blasco-Gimenez, Ramon (Valencia, Polytechnic U.)
Many particle accelerators require to supply chains of magnets with high quality, high magnitude, cycling currents. To do this, the power converters need to provide high output voltages, reaching in some cases tens of kilovolts. [...]

Design Concepts for Medium Voltage DC Networks supplying the Future Circular Collider (FCC) / Colmenero, Manuel (CERN) ; Blanquez, Francisco R (CERN) ; Blasco-Gimenez, Ramon (Valencia U., IFIC)
In the frame of the feasibility studies for the construction of the Future Circular Collider (FCC), a new particle accelerator of 90 km of circumference under design, the use of Medium Voltage DC Grids (MVDC) for distribution has attracted attention considering their potential advantages in terms of transmission losses, power flow control and energy storage integration. Traditionally, the main concerns of the DC networks have been their reliability and robustness. [...]

The Fast Simulation Chain in the ATLAS experiment / Javurkova, Martina (University of Massachusetts (US)) /ATLAS Collaboration
The ATLAS experiment relies heavily on simulated data, requiring the production on the order of billions of Monte Carlo-based proton-proton collisions every run period. As such, the simulation of collisions (events) is the single biggest CPU resource consumer. [...]

Space charge and intrabeam scattering effects for Lead-ions and Oxygen-ions in the LHC injector chain / John, Isabelle (Lund University (SE)) ; Bartosik, Hannes (CERN)
In the context of a possible LHC run with Oxygen-ion beams in about 2023, this report presents results of the space charge and intrabeam scattering effects for the Oxygen beam in comparison to the operational Lead beam in the LHC ion-injector chain (LEIR, PS and SPS). [...]
