 Testing (filled with water) is expected to begin early 2016, with full operation with liquid a few months after that, and Tellurium loading begins in 2017.A neutrino interaction with this liquid produces several times more light than an interaction in a water Cherenkov experiment such as the original SNO experiment or Super-Kamiokande.The energy threshold for the detection of neutrinos can, therefore, be lower, and proton–electron–proton solar neutrinos (with an energy of ) can be observed.
