Response of a nitrogen-filled spherical proportional counter to mono-energetic neutrons
T. Avgitas, M. Axiotis, Z. Balmforth +16
Neutron spectroscopy is an invaluable tool for a wide range of scientific and industrial applications, however, current approaches suffer from limitations that restrict their field…
Reducing simulation-related emissions in rare-event searches through optimised event biasing
P. Knights, L. J. Milligan, K. Nikolopoulos
Rare-event search experiments continue to extend their sensitivities to unprecedented levels. This requires increasingly small backgrounds, and shielding schemes that can suppress…
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…
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…
Transforming a rare event search into a not-so-rare event search in real-time with deep learning-based object detection
J. Schueler, H. M. Araújo, S. N. Balashov +40
Deep learning-based object detection algorithms enable the simultaneous classification and localization of any number of objects in image data. Many of these algorithms are capable…
Performance of a spherical high pressure gas TPC for neutrino magnetic moment measurement
R. Bouet, J. Busto, V. Cecchini +20
The measurement of neutrino magnetic moment larger than would be a clear signature of physics beyond the standard model other than the existence of massive Dirac neut…
Exploring light dark matter with the DarkSPHERE spherical proportional counter electroformed underground at the Boulby Underground Laboratory
L. Balogh, C. Beaufort, M. Chapellier +37
We present the conceptual design and the physics potential of DarkSPHERE, a proposed 3 m in diameter spherical proportional counter electroformed underground at the Boulby Undergro…
Fast Neutron Spectroscopy with a High-pressure Nitrogen-filled Large Volume Spherical Proportional Counter
I. Giomataris, I. Katsioulas, P. Knights +7
We present a fast neutron spectroscopy system based on a nitrogen-filled, large volume gaseous detector, the Spherical Proportional Counter. The system has been successfully operat…
Solar Kaluza-Klein axion search with NEWS-G
G collaboration, Q. Arnaud, L. Balogh +39
Kaluza-Klein (KK) axions appear in theories with extra dimensions as higher mass, significantly shorter lifetime, excitations of the Peccei-Quinn axion. When produced in the Sun, t…
Ionisation quenching factors from W-values in pure gases for rare event searches
Ioannis Katsioulas, Patrick Knights, Konstantinos Nikolopoulos
The effect of ionisation quenching for ions is critical for experiments relying on the measurement of low energy recoils, such as direct Dark Matter searches. We present ionisation…
