Description
Future kilotonne-scale, scintillation-based neutrino detectors, such as Theia, plan to exploit new and yet to be developed technologies to simultaneously measure Cherenkov and scintillation signals in order to provide a rich and broad physics program. These hybrid detectors will be based on fast timing photodetectors, novel liquid scintillators, and spectral sorting. This poster focuses on a currently operating technical demonstrator, called Eos. The novel detector with an approximately 4-tonne fiducial target volume has been constructed at UC Berkeley and LBNL (Lawrence Berkeley National Laboratory). Eos now provides a test bed for the emerging technologies required for hybrid Cherenkov/Scintillation detectors. Eos is now the first multi-ton scale deployment of the higher light-yield version of water-based liquid scintillator (WbLS).
This poster presents the construction and deployment of Eos at Berkeley, deployment of WbLS in Eos, and first results from this data.
