SPEAKER – Edward Callaghan – (UCB) – Optical Neutrino Detectors of the Past, Present, and Future

TITLE: Optical Neutrino Detectors of the Past, Present, and Future

ABSTRACT: Large-volume optical detectors are a mainstay of experimental
neutrino physics, with several successful implementations in the past
decades and larger models on the horizon. Traditionally, such detectors
make use of either Cherenkov radiation, produced as a superluminal
charged particle stops, or scintillation light, produced from the
deexcitation of excited molecular states, but rarely both in tandem. I
will describe an R&D campaign to develop technologies suitable for a
hybrid detector, which will exploit both Cherenkov and scintillation
light to implement advanced event reconstruction techniques. This
campaign has culminated in the Eos demonstrator project, which will be
located on the UC Berkeley campus and act as a ton-scale demonstration
of technologies applicable for Theia, a proposed 25+ kiloton hybrid
detector. I will further discuss my work measuring cosmogenic background
production in SNO, a heavy water Cherenkov detector, and a search for
extraterrestrial antineutrinos in SNO+, an upgrade to SNO, which has
completed a phase of water running and is now filled with liquid
scintillator.
