A Sensor Employing an Array of Silicon Photomultipliers for Detection of keV Ions in Time-of-Flight Mass Spectrometry
/ Mariscal-Castilla, Antonio (Barcelona U.) ; Piller, Markus (CERN) ; Alozy, Jerome (CERN) ; Ballabriga, Rafael (CERN) ; Campbell, Michael (CERN) ; de la Torre, Oscar (Barcelona U.) ; Gascón, David (Barcelona U.) ; Gómez, Sergio (Barcelona, Polytechnic U.) ; Heathcote, David (Oxford U.) ; Mauricio, Joan (Barcelona U.) et al.
Pixellated scintillation detectors have the potential to overcome several limitations of conventional microchannel-plate-based detectors employed in time-of-flight mass spectrometry (ToF-MS), such as extending detector lifetime, reducing vacuum requirements, or increasing the ion throughput. We have developed a prototype comprising a fast organic scintillator (Exalite 404) coupled to an array of 16 silicon photomultipliers (SiPMs), with read-out electronics based on the FastIC application-specific integrated circuit (ASIC).

A multi-domain physics-informed neural network for transient thermal analysis of a Tokamak divertor
/ Rahman, Habib Ur (PIEAS, Islamabad) ; Hussain, Abid (PIEAS, Islamabad ; CERN) ; Ilyas, Muhammad (PIEAS, Islamabad) ; Ahmed, Manzoor (PIEAS, Islamabad) ; Rehman, Haseeb ur (PIEAS, Islamabad)
In this study, a Multi-Domain Physics-Informed Neural Network (MD-PINN) framework is implemented to model a multi-layer transient heat conduction problem with complex boundary conditions in an upgraded mockup of the Pakistan Spherical Tokamak divertor configuration. Automatic differentiation is employed to compute the spatial and temporal derivatives of the temperature field, which are essential for enforcing the residuals of the governing equations, initial conditions, boundary conditions, and interface conditions in the loss function.

Metascintillator pulse feature and shape analysis to detect photoelectric interactions and energy sharing
/ Konstantinou, G (Valencia U., IFIC) ; Latella, R (Valencia U., IFIC) ; Molliner, L (Valencia U., IFIC) ; Zhang, L (Valencia U., IFIC) ; Benlloch, J M ; Gonzalez, A J ; Lecoq, P (Valencia U., IFIC ; CERN)
Metascintillators are scintillator topologies whose principle is based on sharing the energy of an impinging gamma ray between their composing materials. These can be a dense crystal such as LYSO or BGO to retain a high gamma absorption probability, and a fast-emitting compound such as BC-422, EJ232 or BaF$_{2}$ contributing to its light production kinetics.

SPES (Selective Production of Exotic Species) is the Radioactive Ion Beam (RIB) facility that is currently in the installation phase at the Istituto Nazionale di Fisica Nucleare in the Laboratori Nazionali di Legnaro (LNL-INFN). The main purpose of the facility is to deliver neutron-rich radioactive beams with a range of mass between 60 and 160 amu produced as fission products originated within a Uranium Carbide (UCx) target impinged by high energy protons (40–70 MeV).

Design and Characterization of a Radiation-Tolerant Wireless Physical Layer for Control Applications in CERN Particle Accelerators
/ Scialdone, Antonio (CERN ; IES, Montpellier) ; Ferraro, Rudy (CERN) ; Danzeca, Salvatore (CERN) ; Saigne, Frederic (IES, Montpellier) ; Boch, Jérôme (IES, Montpellier) ; Dilillo, Luigi (IES, Montpellier ; U. Montpellier, L2C) ; Masi, Alessandro (CERN)
The article explores the design and radiation characterization of a wireless physical layer (PHY) specifically tailored for equipment control in harsh radiation environments, such as those in particle accelerators like the large hadron collider
(LHC). The PHY, built with commercial-off-the-shelf (COTS), leverages a software-defined radio (SDR), which, compared to dedicated transceivers, provides more flexibility and enables enhanced reliability through mitigation techniques. [...]

Decay spectroscopy of an isomeric state in Md251

Lab. ; LBNL, Berkeley) ; Clark, R M (LBNL, Berkeley) ; Seweryniak, D (Argonne (main)) ; Appleton, C J (LBNL, Berkeley) ; Campbell, C M (LBNL, Berkeley) ; Carpenter, M P (Argonne (main)) ; Chowdhury, P (UMass, Lowell) ; Crawford, H L (LBNL, Berkeley) ; Cromaz, M (LBNL, Berkeley) ; Fallon, P (LBNL, Berkeley) et al.
Excited states in Md251 have been populated by decay of an isomeric state at Ex≈1174 keV and studied via delayed γ-ray spectroscopy. We observe the population of two rotational bands, one of which we identify as the Nilsson π72[514] ground-state band and the other we propose is based on the π92[624] configuration. [...]

FORS: fault-adaptive optimized routing and scheduling for DAQ networks
/ Stein, Eloise (U. Strasbourg ; CERN) ; Bramas, Quentin (U. Strasbourg) ; Pisani, Flavio (CERN) ; Colombo, Tommaso (CERN) ; Pelsser, Cristel (U. Strasbourg ; Cathol. U. Louvain (main))
Data acquisition (DAQ) networks, widely used in scientific research and industrial applications, are composed of numerous interconnected servers, exchanging substantial data volumes produced by large scientific instruments. One traffic matrix generally used in such networks is the all-to-all collective exchange, which demands substantial network resources, making network failures particularly challenging to mitigate.

15 years young: The ALICE TOF detector in the LHC Run 3
/ Strazzi, Sofia (INFN, Bologna ; Bologna U.)
/ALICE Collaboration
The ALICE Time Of Flight (TOF) detector consists of 1593 Multigap Resistive Plate Chambers (MRPCs) operating with a mixture of Freon (93%) and SF6 (7%), covering a total active area of about 140 m2 and accounting for more than 150,000 readout channels. During the latest LHC shutdown, the detector underwent a major upgrade of its readout, allowing for continuous data taking and, therefore, fully exploiting the increased luminosity provided by the LHC in Pb–Pb collisions.
