Description
Abstract: Rare interactions of neutrinos with matter offer the path to understanding important astrophysical phenomena as well as the properties of neutrinos themselves. Neutrinos are also emitted in large quantities from the nuclear fuel cycle, which has led to the emergence of applied antineutrino physics as a sub-discipline that seeks to make use of neutrino detection in nuclear energy and security. This talk will discuss an emerging approach to detecting neutrinos with opaque scintillators. By constraining scintillation photons to a small volume and extracting the signal with wavelength-shifting fibers, interaction topology can be reconstructed with excellent spatial resolution. Originally conceived for reactor neutrino detection, opaque scintillators can relax the material doping constraints and be functionalized for various rare event detection problems where backgrounds must be strongly suppressed. As a more general detection platform, opaque scintillators can be functionalized for practical applications such as neutron/gamma imaging and muon tracking.
