Directional CEvNS Detection for Reactor Monitoring

Neutrinos have long garnered interest as a tool for reactor monitoring, generally by inverse beta decay. However, the recent first measurement of coherent elastic neutrino nucleus scattering (CEvNS) by the COHERENT collaboration has opened up a new measurement channel with a larger cross section than inverse beta decay, though copious cosmic neutrino backgrounds make measurements impossible beyond a few kilometers with existing technologies. I discuss a recent proposal to circumvent this problem with a directionally sensitive CEvNS detector.
