  EOS is a technology demonstrator, designed to explore the capabilities of
hybrid event detection technology, leveraging both Cherenkov and scintillation
light simultaneously. With a fiducial mass of four tons, EOS is designed to
operate in a high-precision regime, with sufficient size to utilize
time-of-flight information for full event reconstruction, flexibility to
demonstrate a range of cutting edge technologies, and simplicity of design to
facilitate potential future deployment at alternative sites. Results from EOS
can inform the design of future neutrino detectors for both fundamental physics
and nonproliferation applications.
