Title: NEW DIRECTIONS FOR NEUTRINO PHYSICS USING NON-CRYOGENIC LIQUID TRACKING
DETECTORS
Host: Svoboda
Room: 416
Abstract: The neutrino physics community faces stark technological tradeoffs between
conventional detectors that offer large target volumes but poor
resolution, and advanced, high resolution detector systems with limited
scalability. In this talk, I present a third way. By fundamentally
reinventing the photodetector, it becomes possible to develop
high-resolution Water Cherenkov (WC) or scintillation-based neutrino
detectors capable of more complete event reconstruction using precision
measurements of the positions and drift times of optical photons. I will
give a brief overview of the Large Area Picosecond Photodetector (LAPPD)
project, an effort to develop compact, microchannel plate (MCP)
photomultiplier tubes capable of sub-millimeter, sub-nanosecond spatial
resolutions and with potential for scalability to large experiments. I
will also discuss steps taken towards the construction of experimental
LAPPD-based neutrino detectors, and the potential applications for such
detector systems in answering the important questions of neutrino
physics.
