Current Status and Future Prospects of the SNO+ Experiment

Table 6

Expected backgrounds in the 5.4–9 MeV energy region during six months of water fill. A fiducial volume cut of 5.5 m is applied to all events. The events after the cut are also shown. ϵ(n) and ϵ(p) are the neutron and proton decay-mode detection efficiencies in the 5.5 m FV and energy window.
