The Next Frontiers in Rare-Event Detection for Science and Security

Executive Summary

We are developing technologies that will enable direct, non-intrusive monitoring of any nuclear reactor via detection of reactor antineutrinos. This technology will help enable the safe roll-out of nuclear energy to nations across the globe, while also advancing the frontiers of nuclear and high-energy physics.
