SNO+ is a multipurpose neutrino experiment located approximately 2 km underground at SNO-LAB, near Sudbury, Canada. The experiment takes a phased approach, transitioning through a water phase and an ultra-pure scintillator phase before loading the liquid scintillator with 0.5 % natural Tellurium, which corresponds to approximately 1330 kg of 130 Te. Water phase began in May 2017 resulting in a number of fundamental physics measurements including: a limit on invisible nucleon decay [1] and a measurement of the 8 Be solar neutrino flux [2]. Scintillator fill began in November 2018 and Tellurium loading is planned for late 2019. During the loaded scintillator phase SNO+ will search for the neutrinoless double-beta decay of 130 Te with an expected effective Majorana neutrino mass sensitivity which will probe the boundary of the inverted mass hierarchy. Additionally, SNO+ aims to measure reactor antineutrino oscillations, low-energy solar neutrinos, geo-neutrinos, to be sensitive to supernova neutrinos, and to search for exotic physics.

“…Most recently, Borexino reported the first direct observation of carbon, nitrogen and oxygen (CNO) neutrinos at 5σ [20]. Five experiments, Borexino [21,22], Super-K [23], KamLAND [24], SNO [25], and SNO+ [26], have measured the higher-energy 8 B flux. COHERENT made the first observation of CEvNS [27], but astrophysical neutrinos have yet to be detected in this way.…”

We detail the sensitivity of the proposed liquid xenon DARWIN observatory to solar neutrinos via elastic electron scattering. We find that DARWIN will have the potential to measure the fluxes of five solar neutrino components: pp, $$^7$$ 7 Be, $$^{13}$$ 13 N, $$^{15}$$ 15 O and pep. The precision of the $$^{13}$$ 13 N, $$^{15}$$ 15 O and pep components is hindered by the double-beta decay of $$^{136}$$ 136 Xe and, thus, would benefit from a depleted target. A high-statistics observation of pp neutrinos would allow us to infer the values of the electroweak mixing angle, $$\sin ^2\theta _w$$ sin 2 θ w , and the electron-type neutrino survival probability, $$P_{ee}$$ P ee , in the electron recoil energy region from a few keV up to 200 keV for the first time, with relative precision of 5% and 4%, respectively, with 10 live years of data and a 30 tonne fiducial volume. An observation of pp and $$^7$$ 7 Be neutrinos would constrain the neutrino-inferred solar luminosity down to 0.2%. A combination of all flux measurements would distinguish between the high- (GS98) and low-metallicity (AGS09) solar models with 2.1–2.5$$\sigma $$ σ significance, independent of external measurements from other experiments or a measurement of $$^8$$ 8 B neutrinos through coherent elastic neutrino-nucleus scattering in DARWIN. Finally, we demonstrate that with a depleted target DARWIN may be sensitive to the neutrino capture process of $$^{131}$$ 131 Xe.
