Edge SpAIce: Deep Neural Network simplification pipeline for On-Board Data Reduction
/ De Vieilleville, François (Unlisted, FR) ; Lemoine, Nicolas-Marcel (Unlisted, FR) ; Coquard, Pierre-Jean (Unlisted, FR) ; Audenino, Pauline (Unlisted, FR) ; Summers, Sioni Paris (CERN) ; Zafirov, Boyan-Nikola (Unlisted, BG) ; Vellas, Simon (Natl. Tech. U., Athens)
Over the past decade, AI-driven algorithms have significantly improved the reliability of object detection in both traditional computer vision tasks and Earth Observation (EO) applications. With the rapid increase in EO satellite deployments and growing constraints on communication bandwidth, there is a critical need for on-board data processing and selection. [...]

High-Precision Cross-Sections for Galactic Cosmic Rays: Highlights from XSCRC2024 and Follow-Up Actions
/ Maurin, David (LPSC, Grenoble) ; Donato, Fiorenza (INFN, Turin ; Turin U. ; CERN) ; Mariani, Saverio (CERN)
The interpretation of high-precision Galactic cosmic-ray data from AMS-02, CALET, DAMPE, etc., is fundamentally limited by nuclear cross-sections uncertainties. This proceeding highlights the results presented at the XSCRC2024 workshop, which aims at bringing together the cosmic-ray, nuclear, and particle physics communities, with the goal of improving cross-section measurements across various domains, from nuclei production for constraining cosmic-ray transport parameters, to antiproton and anti-deuteron production for dark matter searches.

DQE analysis of CdTe and Si sensor Timepix3 detectors
/ Christodoulou, Pinelopi (CERN ; CTU, Prague) ; Campbell, Michael (CERN) ; Genetay, Tristan (CERN ; Unlisted, CH) ; Tlustos, Lukas (CERN ; CTU, Prague) ; Zemlicka, Jan (CTU, Prague)
In this study, the Detective Quantum Efficiency (DQE) was measured by calculating the DQE at zero-frequency, the modulation transfer function (MTF), and the noise power spectrum (NPS) for Timepix3 detectors (pixel size of 55 μm) equipped with 500 μm silicon (Si) sensor and 1mm Cadmium Telluride (CdTe) sensor, with a Tungsten X-ray tube of 40 kVp (narrow-spectrum series (N-series) with beamquality N-40). By comparing these parameters, the impact of sensor material on spatial resolution and noise characteristics was assessed. [...]

SEE and beam characterization with high-energy heavy ions at HIMAC
/ Cecchetto, Matteo (CERN ; IM2NP, Marseille) ; Bilko, Kacper (CERN) ; Emriskova, Natalia (CERN ; IES, Montpellier) ; Alía, Rubén García (CERN) ; Kodaira, Satoshi (Natl. Inst. Quantum Radiological Sci. Tech., Chiba) ; Autran, Jean-Luc (Rennes U.)
Single event effect cross sections and energy deposition events in silicon diodes were measured with high-energy heavy ions at HIMAC, in Japan, by varying LETs through PMMA degraders. Primary beam energies of 178 MeV/n 132Xe and 320 MeV/n 84Kr, measured at the device under test position, were employed. [...]

Reactive laser ablation of copper in hydrocarbon atmosphere: synthesis of nanocomposite surface layers for secondary electron yield reduction
/ Lorenz, Pierre (Unlisted, DE) ; Himmerlich, Marcel (CERN) ; Ehrhardt, Martin (Unlisted, DE) ; Bauer, Jens (Unlisted, DE) ; Lotnyk, Andriy (Unlisted, DE) ; Bez, Elena (CERN ; U. Leipzig (main)) ; Kersten, Holger (Kiel U.) ; Zimmer, Klaus (Unlisted, DE)
•Laser ablation in acetylene forms Cu–C composite nanostructures in one step.•Surface SEY depends on both nanostructure and chemical composition.•Laser treatment allows the reduction of SEY from 2.2 down to 1.2.•Electron conditioning reduces SEY to 0.61 via chemical bond changes.•Carbon-oxide bond reduction is key to SEY suppression after conditioning. The functionality of surfaces is dependent on two characteristic properties: surface topography and chemical composition. [...]

Design of a 25 Gb/s high-voltage radiation-tolerant driver for SiPh modulators in 28 nm CMOS technology
/ Ciarpi, Gabriele (CERN) ; Atzeni, Gabriele (CERN) ; Klekotko, Adam (CERN) ; Biereigel, Stefan (CERN) ; Moreira, Paulo (CERN) ; Kulis, Szymon (CERN)
This work presents the design of a radiation-tolerant high-voltage driver for high-speed electro-optical transmitters implemented in 28 nm CMOS technology. The driver achieves 25 Gb/s modulation with a 3.6 V output swing, effectively bridging the voltage gap between low-voltage CMOS circuitry (0.9 V nominal) and silicon-photonics modulators. [...]

Synthesis and Characterization of Nanostructured Thorium Carbide for Radioactive Ion Beam Production
/ Reis, Edgar (CERN ; Duisburg-Essen U.) ; Celdran, Pedro Amador (European Inst., Transuran. Elem.) ; Walter, Olaf (European Inst., Transuran. Elem.) ; Eloirdi, Rachel (European Inst., Transuran. Elem.) ; Lambert, Laura (CERN) ; Stora, Thierry (CERN) ; Stegemann, Simon (CERN) ; Lupascu, Doru C (Duisburg-Essen U.) ; Rothe, Sebastian (CERN)
Thorium carbide () nano-structured thin disc-like pellets were produced from thoria nanoparticles (-NP) and multi-walled carbon nanotubes (MWCNT). These composites are to be studied as a target material candidate for radioactive ion beam (RIB) production via nuclear reactions upon impact with high-energy proton beams on a stack of solid pellets.

New development in GYAP:Ce multicomponent perovskites
/ Mares, Jiri A (ASCR, Prague) ; Beitlerova, Alena (ASCR, Prague) ; Kotykova, Monika (ASCR, Prague ; Unlisted, CZ ; CTU, Prague) ; D'Ambrosio, Carmelo (CERN) ; Marek, Tomas (Unlisted, CZ) ; Tous, Jan (Unlisted, CZ) ; Polak, Jan (Unlisted, CZ) ; Blazek, Karel (Unlisted, CZ) ; Nikl, Martin (ASCR, Prague)
The detailed scintillation response and properties of newly developed GYAP:Ce single crystals were studied using γ-ray quanta in the 8–1300 keV energy range (light yield, energy resolution, nonproportionality and scintillation decay). The scintillating properties of these multicomponent GYAP:Ce crystals were compared with those of the latest grown YAP:Ce crystals. [...]

Filled Thermoplastic Based Coating for Tailored Contact Resistance in HTS Coils
/ Crescenti, Matteo (PSI, Villigen ; U. Geneva (main)) ; Auchmann, Bernhard (CERN ; PSI, Villigen) ; Brem, André (PSI, Villigen) ; Duda, Michał (PSI, Villigen) ; Kosse, Jaap (PSI, Villigen) ; Müller, Colin (PSI, Villigen) ; Puthran, Kirtana (PSI, Villigen) ; Rodrigues, Henrique (PSI, Villigen) ; Schmidt, Jürgen (PSI, Villigen) ; Senatore, Carmine (U. Geneva (main))
We present a systematic method to tune the turn-to-
turn contact resistance Rct in high-temperature superconducting
(HTS) solenoids by applying a polyvinyl butyral (PVB) thermoplas-
tic coating filled with silver-coated copper flakes (SCCF). The filler
type and its volume fraction determines the accessible resistance
range in the final coil. [...]
