Hydrofluoric acid-free titanium etching for rare-event searches
P. Knights, I. Manthos, K. Nikolopoulos +3
Rare-event search experiments require construction materials with high radiopurity to minimise background contributions. Thanks to its high mechanical strength, low density, machin…
Overlap-aware segmentation for topological reconstruction of obscured objects
J. Schueler, H. M. Araújo, S. N. Balashov +30
The separation of overlapping objects presents a significant challenge in scientific imaging. While deep learning segmentation-regression algorithms can predict pixel-wise intensit…
Materials Design for the Synthesis of High Strength Radiopure Copper Alloys for Rare Event Detection
Dimitra Spathara, Patrick Knights, Konstantinos Nikolopoulos
Additive-free electroformed copper has emerged as the material of choice in exceptionally radiopure detectors for rare-event searches, based on its radiopurity, physical properties…
Design of high-strength, radiopure, electroformed copper-based alloys for rare-event searches: Impact of layer configuration on heat treatments
D. Spathara, P. Knights, K. Nikolopoulos
State-of-the-art and next-generation rare-event search experiments rely on detector materials with stringent requirements on radiopurity and mechanical performance. Additive-free e…
Titanium for rare-event searches: Hydrofluoric acid-free etching
P. Knights, K. Nikolopoulos, G. Rogers +2
Rare-event search experiments require construction materials with high radiopurity to minimise background contributions. Thanks to its high mechanical strength, low density, machin…
Search for Light Dark Matter with NEWS-G at the Laboratoire Souterrain de Modane Using a Methane Target
M. M. Arora, L. Balogh, C. Beaufort +40
The NEWS-G direct detection experiment uses spherical proportional counters to search for light dark matter candidates. New results from a 10 day physics run with a $135\,\mathrm{c…
