The ionization yield in a methane-filled spherical proportional counter
M. M. Arora, L. Balogh, C. Beaufort +40
Spherical proportional counters (SPCs) are gaseous particle detectors sensitive to single ionization electrons in their target media, with large detector volumes and low background…
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…
EXCESS workshop: Descriptions of rising low-energy spectra
P. Adari, A. Aguilar-Arevalo, D. Amidei +303
Many low-threshold experiments observe sharply rising event rates of yet unknown origins below a few hundred eV, and larger than expected from known backgrounds. Due to the signifi…
Measurements of the ionization efficiency of protons in methane
G Collaboration, L. Balogh, C. Beaufort +40
The amount of energy released by a nuclear recoil ionizing the atoms of the active volume of detection appears "quenched" compared to an electron of the same kinetic energy. This d…
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…
Quenching factor measurements of neon nuclei in neon gas
L. Balogh, C. Beaufort, A. Brossard +47
The NEWS-G collaboration uses Spherical Proportional Counters (SPCs) to search for weakly interacting massive particles (WIMPs). In this paper, we report the first measurements of…
Copper electroplating for background suppression in the NEWS-G experiment
G Collaboration, L. Balogh, C. Beaufort +47
New Experiments with Spheres-Gas (NEWS-G) is a dark matter direct detection experiment that will operate at SNOLAB (Canada). Similar to other rare-event searches, the materials use…
A resistive ACHINOS multi-anode structure with DLC coating for spherical proportional counters
I. Giomataris, M. Gros, I. Katsioulas +9
The spherical proportional counter is a gaseous detector used in a variety of applications, including direct dark matter and neutrino-less double beta decay searches. The ACHINOS m…
Precision laser-based measurements of the single electron response of SPCs for the NEWS-G light dark matter search experiment
G Collaboration, Q. Arnaud, J. -P. Bard +36
Spherical Proportional Counters (SPCs) are a novel gaseous detector technology employed by the NEWS-G low-mass dark matter search experiment for their high sensitivity to single el…
