Colloquium – Minfang Yeh – Scintillator Detector for Neutrino Physics

Title: Scintillator Detector for Neutrino Physics

Speaker: Minfang Yeh (Brookhaven National Laboratory, Upton, NY11973, USA, yeh@bnl.gov)

Abstract:

The liquid scintillator detector is known to have low energy threshold, high light yield, and adequate attenuation length with efficient background discrimination in many years of operation for low-energy neutrino detection.  Besides the pulse shape discrimination, an improvement in directionality inherited from the Cherenkov detection is greatly favored for future scintillator detectors.  New detection techniques to separate Cherenkov radiation from scintillation emission are currently under development.  Among these new detector mediums, the water-based liquid scintillator (WbLS) is of great interest from scientific community for multi-disciplinary applications, in particular large-scale physics experiments, due to its unique capability of Cherenkov and scintillation detections and enhancement in chemical safety, metal-loading ability, and cost-efficiency.  The application of scintillator detectors and the development of hybrid detectors including the prototyping study of WbLS demonstrators (1-ton and 30-ton) at BNL in preparation of 10s of kilotons as the target mass for future neutrino detectors will be presented.
