Description
Based at UC Berkeley and LBNL, the Eos detector deploys a range of state-of-the-art detection technologies with the aim of simultaneously utilizing scintillation and Cherenkov photons in neutrino event reconstruction and analysis. New Hamamatsu 14688 PMTs have been measured to have a 450-ps transit-time spread. 12 dichroic light concentrators, which have the ability to spectrally sort photons, have been deployed. Data have been acquired with a variety of unique radioactive sources and a picosecond laser-driven optical system in a water target. With the first phase of data acquisition nearly completed, the 4-tonne capacity acrylic vessel will soon be filled with a water-based liquid scintillator. Eos was designed to have flexibility to test a variety of photodetectors, target materials, and readout technologies, and will continue operating for the next few years at Berkeley, before a possible move to a neutrino source.
