   I don't think that's true. The energies of the neutrinos they are looking at are relative low (less than 15 MeV), and according to https://journals.aps.org/prd/pdf/10.1103/PhysRevD.60.053003 the pos

   Probably if this ever became widespread you could have multiple accelerators around the country shooting "false signal" neutrino beams at the detectors.

   I worked on the SNO+ experiment for grad school and actually got to go in a boat in the ultra pure water surrounding the acrylic vessel to search for leaks. It is an impressive piece of engineering to construct such a detector requiring a l

   They aren't really doing directionality, but the WATCHMAN collaboration ( https://svoboda.ucdavis.edu/experiments/watchman ) is developing detectors like this for nuclear non-proliferation.

   In this case they are detecting inverse beta decay events. The antineutrino interacts with a proton producing a positron and a neutron. The positron annihilates with an electron producing two gamma rays and the neutron then captures on a pr
