The SNO+ Experiment: Current Status and future Prospects — •Johann Dittmer and Kai Zuber — IKTP, TU Dresden, Deutschland
Located at 2 km underground in a mine near Sudbury, Ontario, Canada, the SNO+ experiment has an excellent shielding against cosmic rays. Due to this fact, it is nicely suitable for low background measurements. SNO+ consists of a 12 m diameter acrylic sphere filled with 780 t of a liquid scintillator. The sphere is observed by 9400 photomultipliertubes mounted on support structure with 18 m diameter. The main goal is to search for the neutrinoless double beta decay (0νββ) of 130Te. For this, the scintillator will be doped with 3.9 t of natural Tellurium. Owing to it’s design as a general purpose neutrino detector, it is also possible to measure neutrinos from different sources (geo, reactor, solar, Supernova, etc). After a commissioning water phase ended in 2019, a phase with pure scintillator started in 2022 is currently running. During this phase, reactor neutrino oscillations, low energy 8B solar neutrinos and geo neutrinos are studied. In addition, background components of the 0νββ deacay are investigated. The double beta phase is forseen to run for 5 years starting in 2025.
In this talk, the recent results and the broad physics program will be presented.
SNO+ is funded by the German Research Foundation (DFG).
