“…Multiple experimental efforts for detecting CNNS are made globally: the COHERENT experiment [3] which is currently taking data at the Spallation Neutron Source (SNS) uses a combination of conventional CsI, Ge and liquid-Xe detectors. Various other experiments are planned or being commissioned such as CONNIE [4] using CCDs [5], TEX-ONO [6] using ionization-based Ge detectors, and MINER [7] and RICOCHET [8] using cryogenic detector technology.…”

The $$\nu $$ ν -cleus experiment: a gram-scale fiducial-volume cryogenic detector for the first detection of coherent neutrino–nucleus scattering

We discuss a small-scale experiment, called ν-cleus, for the first detection of coherent neutrino-nucleus scattering by probing nuclear-recoil energies down to the 10 eV regime. The detector consists of low-threshold CaWO 4 and Al 2 O 3 calorimeter arrays with a total mass of about 10 g and several cryogenic veto detectors operated at millikelvin temperatures. Realizing a fiducial volume and a multi-element target, the detector enables active discrimination of γ , neutron and surface backgrounds. A first prototype Al 2 O 3 device, operated above ground in a setup without shielding, has achieved an energy threshold of ∼20 eV and further improvements are in reach. A sensitivity study for the detection of coherent neutrino scattering at nuclear power plants shows a unique discovery potential (5σ ) within a measuring time of 2 weeks. Furthermore, a site at a thermal research reactor and the use of a radioactive neutrino source are investigated. With this technology, real-time monitoring of nuclear power plants is feasible.

“…There have been many attempts over the years, and attempts are ongoing (e.g., [18,19,20,21]) to measure CEvNS at nuclear reactors, where neutrino energies go up about 8 MeV. The CEvNS cross section scales as the square of the neutrino energy; furthermore, the maximum recoil energy also scales as the square of the neutrino energy, T max ∼ 2E 2 ν /M.…”

The COHERENT collaboration measured coherent elastic neutrino-nucleus scattering (CEvNS) for the first time at the Spallation Neutron Source at Oak Ridge National Laboratory, using a CsI[Na] detector [1]. Here we discuss the nature of the CEvNS process, physics motivations, and experimental considerations for measuring CEvNS. We describe the CsI[Na] measurement, along with status and future of COHERENT.

“…The COHERENT experiment will use a stopped pion beam at the Spallation Neutrino Source (SNS) to detect CEνNS with Argon, Germanium, and CsI detectors [20], and will improve upon current NSI limits. The CONNIE experiment is currently using low-threshold CCD detectors near a GW reactor source with near term prospects for measuring the CEνNS process [21], and the TEXONO experiment is developing detectors to measure CEνNS also using a GW reactor neutrino source. These experiments will be sensitive to BSM physics such as NSI and the neutrino magnetic moment [22].…”

Probing light mediators at ultralow threshold energies with coherent elastic neutrino-nucleus scattering

et al. 2017

Light neutral mediators, with mass 1 GeV, are common features of extensions to the Standard Model (SM). Current astrophysical and terrestrial experiments have constrained the model parameter space, and planned experiments around the world promise continued improvement in sensitivity. In this paper we study the prospects for probing light neutral mediators using terrestrial stopped pion and reactor sources in combination with ultra-low threshold nuclear and electron recoil detectors. We show that the coherent neutrino-nucleus and neutrino-electron scattering channels provide complementary sensitivity to light mediators. With low threshold detectors, we show that most stringent bounds on models arise from the nuclear scattering process, improving upon previous bounds from electron scattering of solar neutrinos by nearly an order of magnitude for mediator masses 0.1 GeV.
