Advancements in resistive MPGD: From μ-RWELL technology to high performance Hybrid Layouts
/ Bencivenni, G (Frascati) ; De Lucia, E (Frascati) ; De Oliveira, R (CERN) ; De Robertis, G (INFN, Bari) ; Debernardis, F (INFN, Bari) ; Felici, G (Frascati) ; Gatta, M (Frascati) ; Giovannetti, M (Frascati) ; Licciulli, F (INFN, Bari) ; Morello, G (Frascati) et al.
Future high-energy and nuclear physics experiments require advanced particle gaseous detectors with exceptional tracking and timing performance, capable of operating in harsh environments. The μ-RWELL, a single-stage resistive Micro-Pattern-Gaseous-Detector (MPGD), developed by some of the authors in 2014, achieves gas gains of ∼2×104, ∼100μm spatial resolution, and 5–6ns time resolution.

Fine-tuning machine-learned particle-flow reconstruction for new detector geometries in future colliders
/ Mokhtar, Farouk (UC, San Diego) ; Pata, Joosep (NICPB, Tallinn) ; Garcia, Dolores (CERN) ; Wulff, Eric (CERN) ; Zhang, Mengke (UC, San Diego) ; Kagan, Michael (SLAC) ; Duarte, Javier (UC, San Diego)
We demonstrate transfer learning capabilities in a machine-learned algorithm trained for particle-flow reconstruction in high energy particle colliders. This paper presents a cross-detector fine-tuning study, where we initially pretrain the model on a large full simulation dataset from one detector design, and subsequently fine-tune the model on a sample with a different collider and detector design. [...]

Chaos indicators for nonlinear dynamics in circular particle accelerators
/ Montanari, C.E. (Manchester U. ; CERN) ; Appleby, R.B. (Manchester U.) ; Bazzani, A. (Bologna U. ; INFN, Bologna) ; Fornara, A. (Manchester U. ; CERN) ; Giovannozzi, M. (CERN) ; Redaelli, S. (CERN) ; Sterbini, G. (CERN) ; Turchetti, G. (Bologna U.)
The understanding of non-linear effects in circular storage rings and colliders based on superconducting magnets is a key issue for the luminosity the beam lifetime optimisation. A detailed analysis of the multidimensional phase space requires a large computing effort when many variants of the magnetic lattice, representing the realisation of magnetic errors or configurations for performance optimisation, have to be considered.

Ferrara (main) ; INFN, Ferrara) ; Calore, Enrico (INFN, Ferrara) ; Fiorini, Massimiliano (U. Ferrara (main) ; INFN, Ferrara) ; Gianoli, Alberto (INFN, Ferrara) ; Llopart Cudie, Xavier (CERN) ; Schifano, Sebastiano Fabio (U. Ferrara (main) ; INFN, Ferrara)
DataPix4 (Data Acquisition for Timepix4 Applications) is a new C++ framework for the management of Timepix4 ASIC, a multi-purpose hybrid pixel detector designed at CERN. Timepix4 consists of a matrix of 448×512 pixels that can be connected to several types of sensors, to obtain a pixelated detector suitable for different applications. [...]

Energy efficiency trends in HPC: what high-energy and astrophysicists need to know
/ Suarez, Estela (ZEL, Julich ; Unlisted, FR ; U. Bonn (main)) ; Amaya, Jorge (ESOC, Darmstadt) ; Frank, Martin (KIT, Karlsruhe) ; Freyermuth, Oliver (Bonn U.) ; Girone, Maria (CERN) ; Kostrzewa, Bartosz (Bonn U., HISKP) ; Pfalzner, Susanne (ZEL, Julich)
The growing energy demands of HPC systems have made energy efficiency a critical concern for system developers and operators. However, HPC users are generally less aware of how these energy concerns influence the design, deployment, and operation of supercomputers even though they experience the consequences. [...]

Theoretical determination of the ionization potentials of ScF, YF, LaF, and AcF

We present a comprehensive theoretical study of the ionization potentials of the MF (M = Sc, Y, La, Ac) molecules using the state-of-the-art relativistic coupled cluster approach with single, double, and perturbative triple excitations (CCSD(T)). We have further corrected our results for higherorder excitations (up to full triples), the QED self-energy and vacuum-polarization contributions. [...]

New upper limits for β-delayed fission probabilities of Fr230,232 and Ac230,232,234

The process of β-delayed fission (βDF) of Fr230,232 and Ac230,232,234 was studied in an experiment performed at the ISOLDE facility at CERN. As no fission fragments were observed for any of the nuclei investigated, upper limits for their βDF probability (PβDF) were determined. [...]

/ Techaviseschai, Arnatchai (KMUTT, Bangkok) ; Tarnpradab, Sansiri (KMUTT, Bangkok) ; Chibante Barroso, Vasco (CERN) ; Phunchongharn, Phond (KMUTT, Bangkok)
The ALICE (A Large Ion Collider Experiment) detector at the Large Hadron Collider (LHC), operated by the European Organization for Nuclear Research (CERN), is dedicated to heavy-ion collisions. Within ALICE, the application logs of the online computing systems are consolidated through a logging system known as Infologger, which integrates data from various sources. [...]
