INPA Seminar Speaker: Yashwanth Bezawada(LBL)- Title: Testing Hybrid Optical Neutrino Detector Technologies at Eos
May 1 @ 12:00 pm - 1:00 pm
Date: May 1, 2026
Time: 12:00 pm – 1:00 pm
Location: Sessler Conference Room – 50A-5132 [Hybrid and In-Person]
Speaker: Yashwanth Bezawada (LBL)
Title: Testing Hybrid Optical Neutrino Detector Technologies at Eos
Abstract: 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 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 talk 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 talk presents the construction and deployment of Eos at Berkeley, water phase performance, deployment of WbLS in Eos, and preliminary results from this data.
