Owing to its low electronic noise and flexible target materials, the Spherical Proportional Counter (SPC) with a single electron detection threshold can be utilized to search for sub-GeV dark matter (DM). In this work, we investigate the prospects for light DM direct detection through the DM-nucleus Migdal effect in the DARKSPHERE detector. We consider the different DM velocity distributions and momentum-transfer effects. For Xenon and Neon targets, we find that the DM mass $m_{DM}$ can be probed down to as low as $m_{DM} \sim \mathcal{O}$(10) MeV, and the derived bounds on the DM-nucleus scattering cross section $\bar{\sigma}_{n}$ are sensitive to the high-velocity tails of the DM velocity distribution, which can be altered by orders of magnitude for the different DM velocity distributions in the region $m_{DM} < 10$ MeV.

“…The quenching factor is reconstructed by comparing the signal generated by the recoiling nucleus to the detector calibration performed using radioactive sources, such as 55 Fe. Measurements demonstrating the principle have been concluded [70], and further measurements are ongoing with the gases envisaged for DarkSPHERE.…”

“…A second method is to induce nuclear recoils using the scattering of neutrons of known energy, as employed at TUNL, USA [70]. Pulsed bunches of 20 MeV protons produced by a tandem Van de Graaf accelerator are directed onto a lithium fluoride target, undergo the 7 Li(p, n) 7 Be reaction, and produce monochromatic neutrons.…”

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 Underground Laboratory. This effort builds on the R&D performed and experience acquired by the NEWS-G Collaboration. DarkSPHERE is primarily designed to search for nuclear recoils from light dark matter in the 0.05-10 GeV mass range. Electroforming the spherical shell and the implementation of a shield based on pure water ensures a background level below 0.01 dru. These, combined with the proposed helium-isobutane gas mixture, will provide sensitivity to the spin-independent nucleon cross-section of 2 × 10 −41 (2 × 10 −43 ) cm 2 for a dark matter mass of 0.1 (1) GeV. The use of a hydrogen-rich gas mixture with a natural abundance of 13 C provides sensitivity to spin-dependent nucleon cross-sections more than two orders of magnitude below existing constraints for dark matter lighter than 1 GeV. The characteristics of the detector also make it suitable for searches of other dark matter signatures, including scattering of MeV-scale dark matter with electrons, and superheavy dark matter with masses around the Planck scale that leave extended ionisation tracks in the detector.

“…The variety of neutron production channels can provide beam energies in the 50 keV-30 MeV range. This facility was previously used to evaluate the NR QF for organic scintillators such as EJ-301 [22], EJ-228 [23], EJ-260 [24], stilbene [25,26] and inorganic sensitive media such as two-phase xenon [27] and neon gas [28].…”

We present results of several measurements of CsI[Na] scintillation response to 3–60 keV energy nuclear recoils performed by the COHERENT collaboration using tagged neutron elastic scattering experiments and an endpoint technique. Earlier results, used to estimate the coherent elastic neutrino-nucleus scattering (CEvNS) event rate for the first observation of this process achieved by COHERENT at the Spallation Neutron Source (SNS), have been reassessed. We discuss corrections for the identified systematic effects and update the respective uncertainty values. The impact of updated results on future precision tests of CEvNS is estimated. We scrutinize potential systematic effects that could affect each measurement. In particular we confirm the response of the H11934-200 Hamamatsu photomultiplier tube (PMT) used for the measurements presented in this study to be linear in the relevant signal scale region.
